Describe the process where energy flows through an ecosystem, provide examples.

Food chain.

Explanation:

Food chain can be defined as the process by which energy flows through an ecosystem. The energy from the sun is trapped by plants and transferred from plants to animals.

The energy from the herbivores animals are transferred to carnivores and higher animals.

The flow of energy is unidirectional. It flows from the smaller organism to higher organisms.

Sun →producers→  primary consumers→ secondary consumers→ tertiary consumers

Example: Sun → plants→ rabbit →wolf →lion

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

your answer would be a, maximum exploitation of resources.
