LIFE SCIENCE

Detailed explanation-1: -The higher the organism is on the trophic pyramid, the lower the amount of available energy.

Detailed explanation-2: -The statement is true. Ecological pyramids represent the feeding relationships between trophic levels in an ecosystem. It illustrates the energy, numbers, and biomass at each trophic level.

Detailed explanation-3: -Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

Detailed explanation-4: -Energy is transferred up the pyramid because each organism is consumed by the one above it. The amount of energy available decreases at each trophic level because the transfers are not 100% efficient as only 10% energy is transferred from one trophic level to another.
