The percentage of energy in one trophic level that transfers to the next level in the average ecosystem is 10 percent. Trophic levels are the feeding positions of all organisms that are located in a certain ecosystem. Trophic levels describe what different organisms consume. As energy is transferred from one trophic level to another in an ecosystem, it decreases. Only a small amount of the energy (as little as 10 percent) at any trophic level is moved to the next trophic level. The remaining energy is lost mainly as heat through metabolic processes.
Answer:
See explanation
Explanation:
According to the second law of thermodynamics, energy transfer from one trophic level to another is not 100% efficient. Some energy is lost along the way from one trophic level to another.
The reason for this loss in energy is that the organisms at each trophic level harnesses the energy that they derive from complex organic matter to carry out their own metabolic processes.
Hence, only about 10% of the energy originally derived from complex food materials is passed on to the next trophic level.
Summarily, only about 10 percent of energy derived from food and stored in biomass in a particular trophic level is passed from one level to the next. This is commonly referred to as “the 10 percent rule”. This rule limits the number of trophic levels that can be supported by a given ecosystem.
Answer:
10 percent
Explanation:
When a mouse eats grass only 10% of the energy from the plant is transferred to the mouse what happens to the other 90%
explain the removal from plants on a food web changes the biodiversity in the ecosystem
Answer:
If one species in the food web ceases to exist, one or more members in the rest of the chain could cease to exist too. A plant or animal doesn't even have to become extinct to affect one of its predators.
If carrot sticks are put into water and refrigerated, they become turgid and stiff, but if red blood cells are given the same treatment, they burst or lyse. Explain the difference in the results.
Answer:
Because carrot isn’t the same matter as a red blood cell so if a blood cell gets cold it bursts
Explanation:
They have different chemical compounds
The carrot cells become turgid whereas red blood cells burst or lyse in the given condition due to plant cells have two organelle that prevents it from lysing which are, the cell wall and a large vacuole.
Plant cells have a cell wall around their cell membrane and have a single large vacuole whereas in animals the cell wall is absent and found small vacuoles.
When water moves into a plant (carrot) cell, the vacuole becomes bigger. it causes pressure on the cell wall and increases the turgor pressure within the cell making it stiff. The pressure occurred by the cell wall prevents too much water to enter and prevent cell lysis.It lacks in the animal cells that results in cell lysis due to too much water enters in it.Thus, the difference, in this case, is due to plant cells have two organelle that prevents it from lysing which are, the cell wall and a large vacuole.

Which statement best describes the role of DNA?
It provides a form of energy for cells.
It speeds up chemical reactions inside of cells.
It directly forms proteins.
It transmits genetic information to the next generation.
Answer:
It transmits genetic information to the next generation.
Explanation:
It provides a form of energy for cells. - this is false. DNA does not provide energy. It is the genetic material of the cell
It speeds up chemical reactions inside of cells. - this is false, this vis the role of enzymes when DNA is not
It directly forms proteins. - this is false. DNA does not directly form proteins. It forms proteins via an intermediate molecule, mRNA
It transmits genetic information to the next generation. - this is true. DNA is passed on during cell division to the daughter cells
Viruses reproduce by..... * O sexual reproduction binary fission O asexual reproduction O entering a host cell and making copies of itself
Answer: entering a host cell and making copies of itself
Viruses reproduce by infecting a host cell, and making it produce copies of a virus instead of antibodies. This is how viruses double in your body.

Please Help! Which terms describe the periwinkle snails? Select all that aply more than one answer!
a. herbivores
b. heterotrophs
c. secondary autotrophis
d. members of the second trophic level
e. carnivores
f. primary consumers
Answer:
a, b, d, and f.
Explanation:
The periwinkle snails feed on plants. Consequently, they are said to herbivorous and heterotrophic since they cannot manufacture their own foods. They are also referred to as primary consumers because they directly feed on plants without any other nutritional option. They, therefore, occupy the second trophic level on a typical food web.
The correct options are a, b, d, and f.

Diffusion occurs in gaseous exchange of plants and animals
Diffusion occurs in the absorption of digested food through the villi of small intestine
Explanation:
This happens as a result of exchanging gases i.e carbondioxide and oxygen between animals and plants in respiration
and also digested food through the villi of small intestine to the stomach
Oxygen diffusion in the lungs and Carbon dioxide diffusion from the blood to the air in the lungs are examples of diffusion occurring in the human body.
What are benefits of diffusion to body?Oxygen diffusion in the lungs: Oxygen diffusion is a process that occurs in the human body when oxygen molecules move from an area of high concentration (in this case, the air in the lungs) to an area of low concentration (in the blood). This process occurs across the thin walls of the alveoli in the lungs, and it is facilitated by the presence of tiny blood vessels called capillaries. Oxygen diffuses from the air in the lungs into the blood in the capillaries, where it is carried to the rest of the body to be used for energy production. Oxygen diffusion is important for the body because it provides the oxygen that is needed for cellular respiration, which is the process by which cells produce energy.Learn more about diffusion, here:

what are the differences between sexual and asexual reproduction?
Answer:
Explanation:
DIFFERENCES
SEXUAL REPRODUCTION Sexual Reproduction is a type of reproduction in which one or two organisms or individuals are involved. Fusion of gametes occurs and the offspring’s have different characters. There are sexual organs for both male and female and the organs of both male and female come into contact at the time of reproduction.
ASEXUAL REPRODUCTION Asexual Reproduction is a type of reproduction in which only one organism is involved. There will be no fusion of gametes and The offspring will exactly resemble the parent. There are various kinds of asexual reproduction and some of them are binary fission, budding, fragmentation, parthenogenesis, sports, etc.
