Explain how photosynthesis contributes to the flow of energy in an ecosystem.

• It releases energy stored in glucose

• It captures energy from sunlight and stores it in glucose

• It converts chemical energy into light energy

• It absorbs energy from the soil

What is the role of decomposers in the cycling of matter in an ecosystem?

• They produce energy from sunlight

• They break down dead organisms, returning nutrients to the soil

• They consume producers for energy

• They store energy in the form of fat

Construct a scientific explanation for the role of photosynthesis in the cycling of matter.

• Photosynthesis converts carbon dioxide and water into glucose and oxygen, cycling carbon and oxygen through the ecosystem.

• Photosynthesis absorbs nitrogen from the soil and releases it into the atmosphere.

• Photosynthesis breaks down glucose into carbon dioxide and water.

• Photosynthesis stores energy in the form of ATP.

Develop a model to describe how food is rearranged through chemical reactions to release energy.

• Food is broken down into glucose, which is then used in cellular respiration to release energy.

• Food is converted directly into energy without any chemical change.

• Food is stored as fat and not used for energy.

• Food is absorbed into the bloodstream without any change.
