Which example is a representation of the amount of chemical energy at each trophic level?
energy pyramid
primary productivity
food chain
joule
Answer:
food chain
Explanation:
The energy pyramid is a representation of the amount of chemical energy at each trophic level. Therefore option A is correct.
An energy pyramid is a graphical representation of the amount of chemical energy available at each trophic level in an ecosystem. It shows the flow of energy from one trophic level to the next, with energy decreasing as it moves up the pyramid.
The primary producers (plants or autotrophs) occupy the bottom level and contain the most energy. As energy is transferred to higher trophic levels through consumption, it decreases, resulting in fewer organisms and less energy available at each subsequent level.
Energy pyramids help illustrate the inefficiency of energy transfer in ecosystems and the importance of a stable base of primary producers to support higher-level consumers.
Therefore option A is correct.

Explanation:
The reason muddy water becomes so clear and looks almost drinkable at the end of a stream is because of a process that is called self-purification. This is a natural process of purifying, as the ability of a body of water to rid itself of pollutants.
