Only about 10 percent of energy at any given level will make it to a higher one.

Do the biomass of organisms in a typical ecological pyramid increases at each level?
The biomass of each organism decreases with each level. With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level.
True or false about 20 of the evergy found on a trophic leve is passed on a higher trophic level?
no only 10% of the enregy is passed tot the higher trophic level
What proportion of the energy in the ecosystem is transferred from one trophic level to the next?
Only about ten percent of energy is transferred from one trophic level to the next in an ecosystem. This is why the amount of animals in higher levels is smaller.
What is the mosquito trophic level?
Mosquitos can be of many different trophic levels, as they consume the blood of animals from multiple trophic levels.
What is an example of an animal that fill more that one trophic level?
Any omnivore is in more than one trophic level, such as a chicken that eats both heterotrophs (worms) and autotrophs (grain)
Why are some pollutants more harmful to organisms at higher trophic levels?
Higher trophic levels are animals that are higher up on the food chain. When animals lower on the food chain get effected by pollutants, it transfers to the animal that eats that one. And so on. So the animals on the higher trophic level eat the most animals(animals with the pollutants).

What happens when an organism from a higher trophic level eats an organism from a lower trophic level?
When an organism from a higher trophic level eats one from a lower trophic level, it gains energy and nutrients from the consumed organism. This contributes to the transfer of energy through the food chain and helps regulate population sizes in the ecosystem.

Only about ten percent of energy is transferred from one trophic level to the next in an ecosystem. This is why the amount of animals in higher levels is smaller.

Animals that feed on plants are in what trophic level?
In which trophic level are all plants found?

Mosquitos can be of many different trophic levels, as they consume the blood of animals from multiple trophic levels.
What is the relationship between the trophic level of an organism and the concentration of DDT in its body?
If an animal on a high trophic level eats other organisms on a lower trophic level effected by DDT, the animals level will be affected.
What the second trophic level?
Animals, human beings
Is entropy is greater at higher trophic level than a lower level?
False
