Approximately what percentage of the energy in one trophic level becomes incorporated into the next level?
A) 1%
B) 10%
C) 30%
D) 60%
E) 100%
Trophic Level
A position in a food chain or ecological pyramid occupied by a group of organisms with similar feeding mode (e.g., primary producers, herbivores, carnivores).
Energy Incorporation
The process of converting energy from one form into another form usable by an organism, often involved in metabolism and bodily functions.
Percentage
A proportion or share in relation to a whole, represented as a fraction of 100.

Final Answer :
B
Explanation :
The 10% rule states that approximately 10% of the energy available in one trophic level is incorporated into the next trophic level. This is due to energy loss through processes such as cellular respiration, heat loss, and incomplete digestion. Therefore, only a small fraction of the energy from the original food source is available to higher trophic levels.
