Determine which of the following statements is true about energy in ecosystems.
A. Primary producers lose 20% of the energy they absorb as urine and feces.
B. Consumers pass on 20% of the energy they get from a lower trophic level.
C. Primary consumers lose 60% of the energy they absorb from producers as urine and feces.
D. 10% of the energy Primary consumers absorb is lost as heat.

The community along with the biotic and abiotic factors makes the ecosystem. In the ecosystem, 10% of the energy primary consumers absorb is lost as heat. Thus, option D is correct.

An ecological pyramid is the graphical presentation of the organism and the flow of energy at each trophic level. The trophic level constitutes the producers and the consumer.

The flow of energy follows the 10% energy rule where each trophic level loses and gains only a certain amount of heat. The heat is lost as excretory products in the environment.

The maximum amount of energy is gained by producers which passes to the primary consumers (10%), secondary consumers (1%), and the upper trophic level.

Therefore, option D. primary consumers absorb only 10% of energy.
