Which of the following is a true statement about the flow of energy in an ecosystem?
a. smaller organisms need less energy per gram of body weight than do larger organisms.
6. energy transfer between organisms normally involves conservation of heat energy.
c. energy is lost between trophic levels.

Energy is lost between trophic levels.

 Option C

Explanation:

The source of energy for all organisms is the Sun. The Tropic levels exhibit the flow of energy in an ecosystem. The flow of energy is always in one direction. The energy level decreases crossing each trophic level as energy is lost in the form of heat.

Primary producers are the first in Trophic level, The Herbivores fall in the next level , the Carnivores form the next level and the decomposers are the last in the trophic level. The decomposers decompose all the living organisms and convert to nutrients that are available in the soil. The plants take up this nutrient and hence this is a cycle.

uh two lol
