Question

Which of the following can explain the energy stored in an ecosystem?
A. Pyramid of biomass
B. Food chain
C. Pyramid of energy
D. Food web

Answer 1

Hint: Pyramid of energy is the stored biomass in an ecosystem of each trophic level. The energy of each level is stored as biomass. Biomass decreases at each ascending level of the food chain.

Completanswer:The forest ecosystem is an upright pyramid but the aquatic ecosystem is an inverted pyramid.
The inverted pyramid depicts that the producers have less biomass in an aquatic ecosystem.

So, the answer is A. Pyramid of biomass

Additional information: A food chain is the representation of how the organisms are related to each other by the food they eat. Each level of a food chain represents a different trophic level.
A pyramid of energy or pyramid of productivity is the rate at which energy or mass is transferred from one trophic level to the next. It is the flow of energy through the food chain.

Note: When an ecosystem is healthy, the graph produces a standard ecological pyramid. This is because, in order for the ecosystem to sustain itself, there must be more energy at lower trophic levels (producers) than there is at higher trophic levels(carnivore).
The entirety of interrelated food chains in an ecological community is the food web.
The energy flow in an ecosystem is depicted through a pyramid of energy.
