Question

ENERGY PYRAMIDS

Energy pyramids show the relative amount of
energy that is available to each trophic level.
Only about 10% of the energy available in
one trophic level is transferred to organisms in
the next trophic level. The other 90% is lost
through heat and other body processes.
1. List 2 body processes in which you think
energy is lost.​

Answer 1

Energy is lost at several levels from the body of an organism. Two of the phenomenons through which energy is lost are

Conduction:

When a body is in contact with another body, energy is lost in the form of heat. For example, if we sleep on a cold floor, energy from our body would be lost to the floor in the form of heat,

Decomposition:

Energy is lost when cells in a body die and energy is required for decomposition also.
