Question

Only 10 percent of the energy stored in an organism can be passed on to the next trophic level. Of the remaining energy, some is used for the organism’s life processes, and the rest is

Answer 1

Answer:

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

Answer 2

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

Explanation:

• Only around 10% of the energy stored as biomass in a trophic level gets transmitted from one trophic level to the next on average.
• The "10% rule" sets a limit on the number of trophic levels that an ecosystem may support.
• The remaining 90% is used to live, develop, and reproduce, with the remainder being lost to the environment as heat. Energy from the Sun is delivered to the first trophic level of producers in all energy pyramids.
