Question

"If 1,000 J of energy is captured by primary producers in an ecosystem, how much energy would typically be passed on to the consumer at the next level of the food web for that ecosystem?

A) 1,100 J
B) 100 J
C) 1,000 J
D) 10 J

Please select the most appropriate option that represents the typical energy transfer."

Answer 1

Typically, only about 10 percent of the energy captured by primary producers is transferred to the next trophic level. Therefore, if primary producers capture 1,000 J of energy, approximately 100 J would typically be passed on to the consumers.

Step-by-step explanation:

If 1,000 J of energy is captured by primary producers in an ecosystem, typically only about 10 percent of this energy is passed on to the consumers at the next level of the food web. This concept is known as ecological efficiency or trophic level transfer efficiency (TLTE), which is the measure of energy transfer between trophic levels. Therefore, the correct option would be B) 100 J, as this represents the typical energy transfer from primary producers to primary consumers according to the 10 percent rule.
