Question:
Solution:
A) A food chain is a sequence of transfers of food and energy when one organism is consumed by another organism in an ecosystem. In an energy pyramid that is intrinsically related to the food chain, producers are present at the base trophic level. These organisms exhibit the highest amount of energy compared to other trophic levels. That is because these organisms are capable of producing their own food through the photosynthesis process, obtaining energy from sunlight or through chemosynthesis.
Energy is stored in organic molecules can be transferred to other organisms in the ecosystem when these organisms eat plants or other organisms that have previously eaten plants are eaten. In this way, all consumers (or heterotrophs) of an ecosystem depend on the energy producers of the ecosystem. Therefore, we can say that producers support all other organisms in an ecosystem.
So that, we can conclude that the correct answer is:
PRODUCERS.
B) Since producers support all other organisms in an ecosystem, the abundance of producers, biomass, and rate of energy capture is key to understanding how moves energy through an ecosystem.
This flow of energy can be understood through the ecological pyramids that are visual representations of the flow of energy, the accumulation of biomass, and the number of individuals at different trophic levels.
Thus, analyzing these ecological pyramids, we can say that the correct answer is:
Energy can pass from one trophic level to the next when organic molecules from the body of one organism are consumed by another organism.
