Science 7 Unit 3 Kelp Forest Pre-test

Producers make their own food. Some use energy from chemicals in the environment but most use energy from the sun in a process known as _____1________. During this process organisms take carbon dioxide gas out of the atmosphere and water from the environment. They combine them to store energy as _____2_____. In the process, they create oxygen as a waste product that helps animals and many other organisms to gain energy from their own food.

Which statement best summarizes what happens to energy in an ecosystem when it reaches the top of the food chain?

• The flow of energy stops when the top predator dies.

• The flow of energy stops when a secondary predator decomposes.

• The energy flows in the opposite direction, back down the food chain.

• The energy is transferred to the soil and recycled back to the producers.
