Energy transfer in an ecosystem

What happens to the amount of energy available to organisms when moving from trophic level 1 to trophic level 2?

• The energy decreases by approximately 90%

• The energy increases by approximately 90%

• The energy increases by approximately 10%

• The energy decreases by approximately 10%

How is energy released by an organism? (This includes plants and animals.)

• It is used up by the animal and not released

• It is recycled by decomposers

• It is stored as biomass

• It is released into the ecosystem as heat.
