The first question says “Use the T chart to list at least 3 differences (Ecological Principles) between the movements of energy and matter through the ecosystem” I need help really bad on this so I’d highly appreciate is someone would help me on this (You have until May to answer these questions + I will be providing 50 points)
The differences between the energy flow and matter cycling depend on the number of trophic levels in the ecosystem.
What do you mean by Ecosystem?The Ecosystem may be defined as the area or place where organisms of different species live and interact with each other in a well-defined way.
The first key difference between energy flow and matter cycling is that the energy flow shows the transmission of energy from one trophic level to the other in the food chain, while matter cycling shows the cycling of elements throughout the living and non-living parts of the ecosystem.
Energy flow always follows a fixed and definite pathway, while matter cycling randomly works in the ecosystem.
As energy moves through an ecosystem, it changes form but no new energy has been synthesized. Matters flow throughout the ecosystem, atoms are rearranged into various other molecules as per requirement but no new matter is created.
Therefore, the differences between the energy flow and matter cycling depend on the number of trophic levels in the ecosystem.

Discuss why photosynthesis is important for humans and life?
Answer:
Here is my answer.
Explanation:
The process of photosynthesis is essential to all living organisms, because it is the primary source of oxygen in the atmosphere. As a result, the carbon cycle could not occur. Plants and oxygen-requiring life would not survive without photosynthesis. Photosynthesis is the process of making food from light, carbon dioxide, and water in the air: It is the main energy source for green plants and trees. Photosynthesis produces oxygen, which we need for survival. Without photosynthesis, the world would have little to no oxygen.
Let me know if you need help :)
Answer:
It provides human's and organisms with food and energy.
Explanation:
Not only does photosynthesis produce crops such as wheat and carrots which are primary foods in our diets, it also is responsible for heat and many of the materials we use (such as cotton for fabric). Photosynthesis also provides light and electricity through reusable energy.

Alien Taxonomy Project IN THE YEAR 2525 Humans, after hundreds of years of constant effort, have successfully polluted all bodies of water on Earth. As a result, almost all previously known species of plant, animal, and other life have become extinct. Through natural selection, genetic engineering, and selective breeding programs, a portion of the Earth has been successfully repopulated. The following organisms are all that remain: 1. Photosynthetic sun-basking sharks. Their green fins have chlorophyll to convert sunlight to energy (autotrophs). 2. Chemosynthetic goldfish that convert pollution to food (autotrophs). 3. Aquatic humanoids whose main diet is aqua-wheat and basking sharks. They have fins instead of legs (heterotrophs). 4. Aqua-wheat: one of the few plants that remain, it is similar to algae. 5. Terrestrial Humanoids with 4 arms, their diet consists of butter-roaches and fuzzy hamsters. 6. Tentacled aqua humanoids, they only feed on aqua-wheat and have tentacles for arms and legs. 7. Cockroaches that feed on humanoid waste. 8. Giant Aqua-spiders that live in water and feed on goldfish and basking sharks. 9. Green-haired rats that are photosynthetic. 10. Parasitic mosquitoes that feed off any humanoid 11. Ten-legged fleas that live on the photosynthetic rats and drink blood. 12. Poison Grass - this plant is a hybrid between grass and poison ivy. The plants are toxic to almost everything (autotrophs) 13. Fuzzy hamsters with green hair that use the sunlight to make their food, thought to be related to the rats. 14. Butter-roaches: genetic engineering created these butterfly-like creatures from cockroaches. Butter- roaches eat poison grass. YOUR ASSIGNMENT: 1. As an alien taxonomist, it is your responsibility to classify these existing organism types. Create a taxonomic scheme using only kingdom, phylum, genus, and species. The intermediate categories have been eliminated since the total number of species has been drastically reduced. (Two Kingdoms are recommended). Each new group needs a name and a de

How are organisms classified at each taxonomic level?The recent taxonomic system now has 08 stages in its hierarchy, from down to up , they are: species, genus, family, order, class, phylum, kingdom, domain. Thus species are grouped within genera, genera are grouped within families, families are grouped within orders, and so on.

On the island of Hawaii, Keanu notices that the sand on the beach is black, the same color as the rock formations on the island. Keanu realizes the sand used to be part of the rock formations. How did material from the rock formations turn into sand?
Answer:
It turned into sand from erosion. Or to break it down specifically the waves constant crashing on the rocks broke it apart little by little and the pieces of rock that fell into the water were tossed and bashed around even more until they broke into such fine pieces of rock, which is then called sand. The reason that the color of the sand matches that of the surrounding rock is because during this process it doesn't effect the original color of the rock.
Explanation:
Answer:
the answer is the weather
Explanation:
Magma rises to Earth's surface, such as through a volcanic eruption, where it cools and hardens into igneous rock. On the surface, weathering and erosion break down the igneous rock into pebbles, sand, and mud, creating sediment, which accumulates in basins on the Earth's surface

If the lysosome is damaged,worn out tissues from the cell won't get rid.
If the vacuile is damaged osmotic pressure of the cell will be interfered with.
If endoplasmic reticulums are damaged,transport of proteins and lipids won't take place.
if a species has a wide range of tolerance, will it dominate a habitat in low pollution or high pollution? why?
A species with a wide range of tolerance can dominate most habitats due to its ability to adapt.
What is a wide range of tolerance?A wide range of tolerance is the ability for an organism to tolerate low or high levels of abiotic contamination in it's natural habitat. This means that the organisms in question show a high level of adaptability and are able to survive in hostile environments. This allows them to remain dominant in most habitats despite contamination values.

The yellow ring inside the bacterial cell represents the bacterial DNA. Why does this structure
disappear by step 3 of the lytic cycle?
Answer:
Explanation The bacterial DNA structure will disappear because of ; The usage of the ribosomes of the bacterial cell by the nucleic acid injected by the virus.
The lytic cycle which is one of the cycles of viral reproduction is the cycle which leads to the breakup of the DNA of the cell ( i.e. destruction of the host cell and its membrane).
Therefore the yellow ring inside the bacterial cell will disappear by step 3 after which the nucleic acid is injected into the host cell by the virus .
Hence we can conclude that the bacterial DNA structure will disappear because of the usage of the ribosomes by the nucleic acid from the virus
