Which level of consumer has access to the smallest supply of energy?

a. primary
b. secondary
c. tertiary
d. quaternary

Answer;

Quaternary level

Explanation;

-About 90% of the energy  in food is lost at each trophic level when an organism is eaten, so it is less efficient for a tertiary or Quaternary consumer to be a higher order consumer than a primary consumer. Therefore, the energy transfer from one trophic level to the next, up the food chain, is like a pyramid; wider at the base and narrower at the top. Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.

-Therefore, Quaternary consumers such as hawk, owl etc. have access to the smallest supply of energy.

the answer is b, have negligible mass

i think it's 35 meters
