Energy Flow

  • Energy enters the system as sunlight converted by producers.

  • Producers are eaten by consumers, which are then eaten by another consumer and so on.

  • Movement of energy can be shown as food chains, food webs, and energy pyramids.

Multiple Choice

What is the ultimate source of energy for most organisms?

1

The Sun

2

The Earth

3

Plants

4

Producers

4

Food Chain

A food chain is linear. It shows a direct path a energy from a producer to the next consumer.

Energy Pyramid

  • Shows the amount of energy that moves from one feeding level to another in a food web.

  • Only about 10 percent of the energy at one level of a food web is transferred to the next higher level.
