Question

In the ecosystem, the 10% energy is transferred from one trophic level to another in the form of
(a)Heat energy
(b)Light Energy
(c)Chemical Energy
(d)Mechanical energy

Answer 1

Hint: When organic molecules from the body of an organism are eaten by another organism, energy can move from one trophic level to the next. However, it is not typically very effective to transfer energy between trophic stages.

Complete answer:
-Energy is passed through the food chains, but from one trophic stage to the next, the amount of usable energy decreases.
-The explanation for this is that only about 10 percent of the energy is transferred to the next trophic stage.
-This 10% energy is transferred in the form of chemical bonds present as in biomass(organic molecules) of the organism when consumed is converted into ATP via respiration.
-Large amounts of energy are lost from the ecosystem between one trophic level and the next level as energy flows from the primary producers through the various trophic levels of consumers and decomposers.
-The main reason for this loss is the second law of thermodynamics, which states that whenever energy is converted from one form to another, there is a tendency toward disorder (entropy) in the system.
-Energy diminishes as it climbs trophic levels since energy is lost as metabolic warmth when the creatures from one trophic level are devoured by life forms from the following level.
-Trophic level exchange proficiency (TLTE) measures the measure of energy that is moved between trophic levels.
So, the correct answer is ‘Chemical energy’.

Note: -Net efficiency of production (NPE) determines how effectively each trophic level utilizes and transforms the energy from its food into biomass to fuel the next trophic level.
-Endotherms have a low NPE and need more energy for heat and respiration than ectotherms, so to get the energy they need for survival, most endotherms have to feed more often than ectotherms.
