Question

In an ecosystem, only 10% of the energy in one trophic level is transferred to the level above it. The rest of the energy is lost to the environment.

If the first trophic level (green plants) contains about 200,000 kcal of energy, how much energy is transferred from frogs to snakes?

Answer 1

Explanation:

The green plants are eating by frog's so

200000*10/100=20000kcal energy is transferred to frog and snakes eat frog's so

20000*10/100=2000kcal

so 2000kcal of energy is transferred from frogs to snakes

Answer 2

A pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels.
