Answer:
All ecosystems are made up of abiotic and biotic components.
biotic factors are living things, such as plants or animals.
abiotic factors are nonliving things, such as wind, temperature, or moisture.
producers are organisms that get their energy from nonliving resources, meaning they make their own food. These organisms are also called autotrophs.
consumers are organisms that get their energy by eating other organisms. These organisms are also called heterotrophs.
Why are producers so important to an ecosystem?
They create the base of the food chain/food web
Explanation:
The answers can be explained as:
1.Ecosystem is made up of biotic and abiotic compoenents. Biotic components refer to the living things whereas the abiotic components are the water, soil, air, and minerals.
2. Biotic factors are the living components of the ecosystem, which are plants, animals, and microorganisms.
3. Abiotic factors are the non-living components, which include moisture, temperature, air, and minerals.
4. Producers are the organisms that prepare food in the presence of light, water, and gases. These organisms are also plants or autotrophs.
5. Consumers are the organisms that feed on the producers to obtain energy. These organisms are known as heterotrophs.
6. Producers are the organisms that prepare food for the organisms. These are essential for the ecosystem as all organisms are dependent on each other and require food for survival.

Which cell contains membrane bound organelles in addition to a cell wall and chloroplast
Answer:
Eukaryotic cells
Answer:
plant cells and eukaryotic algae
Explanation:
Only plant cells and some algae have chloroplasts.
The human population has increased rapidly since the 1700’s. For most of human
history, there were fewer than half-billion people on Earth. In mid- 2009, 6.7 billion
people inhabited our planet. Because of these, extensive pollution is everywhere. As
a student, what can you do to save not only a particular system, but the Earth
itself? Write your answer in the table.
Answer:
to sow awareness in the community about the importance of caring for our environment
Explanation:
The pollution is the adverse introduction of contaminants in the environment by human action. Pollutant compounds have different origins and they appear in the form of chemical substances, noise, heat, light, etc. The best way to avoid pollution on our planet is to raise initiatives for improving environmental policies and thus promoting sustainability in our communities. It seems like a small contribution, but it is important to have into account that behavior change is the most powerful thing that we have to produce big results.
Some good ways to avoid pollution are:
-Restricting the use of the wood stoves
- Reduce the kilometers in your car
-Avoid burning trash, and other substances
- Avoid the use of plastic material (such as plastic bottles)
Use of electric vehicles, grow more trees, dumping waste material far from the water bodies and avoid cutting of forests.
In order to save the earth we have reduce those activities which produces pollution, grow more trees, dumping waste material far from the water and avoid cutting of forests. We have to use electric vehicles as compared to vehicles which runs on the fossil fuels because electric vehicles produces no pollution.
Whereas fossil fuel vehicles produces high amount of carbondioxide which causes global warming and climate change. Planting of trees cleans the air and reduces pollution so we can say that these actions can save our earth from destruction.

A student puts drops of Lugol’s iodine solution into the water in the beaker shown. The water turned red. After a short time, the starch solution inside the dialysis tubing turned black. Which function of the cell membrane was the student demonstrating?
Facilitated diffusion of starch
Active transport of hydrogen ions.
Diffusion through a non-permeable membrane
Diffusion through a semi-permeable membrane
Answer:
Diffusion through a semi-permeable membrane
Explanation:
A membrane that would only allow water, ions and certain molecules to pass through it by diffusion while restricting other large molecules molecules from passing through is called semi-permeable membrane
The iodine molecules were dissolved in the water in the beaker to form iodine solution.When the starch in the tubing was immersed into the red iodine solution, the molecules of iodine diffuse across the tubing walls which acts as the cells membrane -selectively permeable membrane to react with the starch solution. The reaction turns the starch blue black
The characteristic of the cell membrane is due to the lipid bi-layer which allow certain substance pass through while restricting others because of the inner hydrophobic (water hating) and outer hydrophilic phospholipid layer. (water loving layer)These forms the double bi layer to selectively control the movement of substances across it.
Which group in an ecosystem performs photosynthesis?
A. Autotrophs
B. Secondary consumers
C. Heterotrophs
D. Primary consumers
Answer:
its A
Explanation:
An autotroph or primary producer is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) using carbon from simple substances such as carbon dioxide, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis). Autotrophs do not need a living source of carbon or energy and are the producers in a food chain, such as plants on land or algae in water (in contrast to heterotrophs as consumers of autotrophs or other heterotrophs). Autotrophs can reduce carbon dioxide to make organic compounds for biosynthesis and as stored chemical fuel. Most autotrophs use water as the reducing agent, but some can use other hydrogen compounds such as hydrogen sulfide. hope this helps :D

define the term “cellular respiration” using the words energy,carbon dioxide,and oxygen.
Answer:
Cellular respiration is the process of cell catabolism in which cells turn food into usable energy in the form of ATP. In this process, glucose is broken down in the presence of molecular oxygen into six molecules of carbon dioxide, and much of the energy released is preserved by turning ADP and free phosphate into ATP. This typically involves the transfer of oxygen and production of carbon dioxide and water as end products.

Which of the following gives water its cohesive properties? And explain why.
b. Water’s polarity makes it attracted to other charged molecules.
c. Ionic bonds hold neighboring water molecules together.
d. The overall negative charge of water molecules prevents attraction to other substances
Answer:
Water is a polar molecule and also acts as a polar solvent. When a chemical species is said to be "polar," this means that the positive and negative electrical charges are unevenly distributed. The positive charge comes from the atomic nucleus, while the electrons supply the negative charge. It's the movement of electrons that determines polarity. Here's how it works for water
Explanation:
The cohesive properties of water are given to it due to - b. Water’s polarity makes it attracted to other charged molecules.
Cohesion property is the property that is the attraction of different molecules of the same kind. Water is highly cohesive as Its molecules show strong attraction forces.
The cohesive property of water is due to the hydrogen bonds in between hydrogen and oxygen molecules of the water molecule.Hydrogen bonding makes slightly positive and negative charges of the hydrogen and oxygen atoms makes water molecules polar.This polarity leads to the attraction of the water molecules known as cohesive property.Thus, the correct answer is - b. Water’s polarity makes it attracted to other charged molecules.

what is the role of photosynthesis in the cycling of matter and low of energy within a cell ?
[tex]\huge{\purple{\bigstar{\pink{\text{ANswER}}}}}[/tex]
The process of photosynthesisconverts light energy into stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen.Cellular respiration releases the energy needed to maintain body temperature despite ongoing energy transfer to the surrounding environment.The process of photosynthesis directly involves the cycling of matter as it converts the radiation energy from the sun to stored chemical energy.
What is Photosynthesis?Photosynthesis may be defined as a type of process through which green plants and some photosynthetic algae synthesize their own in the form of glucose food with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis is as follows:
[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O[/tex].Apart from photosynthesis, the mechanism of cellular respiration directly involves the cycling of matter.
This is because the reactants of cellular respiration are the products of photosynthesis and the reactants of photosynthesis are the product of cellular respiration.
The process of cellular respiration involves the derivation of energy from complex food molecules in the presence of oxygen.
Therefore, the process of photosynthesis directly involves the cycling of matter as it converts the radiation energy from the sun to stored chemical energy.

Explanation:
molecules move in and out of a cell by diffusion. the picture shows a cell molecules both inside and outside the cell how will the molecules in this illustration move as a result of diffusion
out of the cell
into another cell
to the extern environment
into the cell
Answer: The molecules on the exterior of the cell will move inwards due to the difference in concentration
Explanation:
This happens because of Endosmosis, where the water molecules move from a region of higher concentration to a region of lower concentration through a semi-permeable membrane. Endosmosis is when the cell swells up due to a higher concentration in the exterior of the cell and a lower concentration in the interior of the cell.
Therefore, the water molecules move inside the cell until the concentrations of the exterior and the interior of the cell is balanced
Going by the diagrammatic illustration, the molecules would move into the cell until an equilibrium is reached.
Diffusion generally involves the movement of molecules from the region of higher concentration of a molecule to the region of lower concentration of the same molecule. The net movement will continue until both sides have equal concentrations of the molecule.
Looking at the diagram, there are more of the molecule outside the cell than inside of it. Thus, the molecules will keep moving inside the cell until both the outside and inside have the same concentration.

The development of the two types of forests has negatively affected populations of shrubs
Answer:
Yes, shrubs are affected.
Explanation:
The development of a pine and then a hardwood forest affected populations of shrubs because pine and hardwood trees are higher in length than shrubs so the shrubs did not gain sunlight and also all the nutrients present in the soil is extracted by the pine and hardwood trees. The shrubs present below the pine and hardwood trees slowly removes from that environment due to unavailability of sunlight and nutrients.
