Question

Read the following claim.

The energy animals need to survive was once energy from the sun.

What evidence from the article supports this claim? Think about energy pyramids, then explain how the evidence from the article supports this claim.

Answer 1

Answer: The energy from the sun is the only source of energy which has the ability to sustain life on earth.

The energy pyramid states that the transfer of energy is unidirectional and it flows from the producers to the consumers.

There are different trophic levels at which the organism are found say herbivores, carnivores and top predators.

All of the organism are dependent on the producers for their source of energy.

hence, the sunlight helps autotrophs to make food and herbivores feed on them and then the carnivores animals feed on herbivores and then the top predators feed on the carnivores animals.

So, ultimate source of energy on earth is sun, which directly or indirectly provides energy to the producers and other animals.
