The flow of energy through living systems can be modeled as food chains, food webs, or energy pyramids. The energy organisms need to live and grow first enters the ecosystem when which of the following occurs? 1.Plants take in light energy from the sun. 2. Decomposers break down dead organisms 3.Primary consumers eat plants for food 4. Secondary consumers eat primary consumers

This is because plants are the very first on all the things listed above ( food chains, food webs, and energy pyramids) and then continue to be eaten and adding the energy in the process.

The energy organisms need to live and grow first enters the ecosystem when Plants take in light energy from the sun.

These energy and nutrients from plants are passed around through the food chain, when one organism eats another organism.

Finally, the energy remaining in a dead organism is consumed by decomposers. these nutrients can be cycled through an ecosystem but energy is simply lost over time.

Food chain

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

The levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers.
