TN READY Photosynthesis, Food Chains and Roles of Organisms

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to make their own food from carbon dioxide and water.

Front

What do plants absorb during photosynthesis?

Back

Plants absorb carbon dioxide from the air and water from the soil.

Front

What is the role of leaves in photosynthesis?

Back

Leaves are the main site of photosynthesis; they contain chlorophyll, which captures sunlight.

Front

What is a food chain?

Back

A food chain is a sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

Front

What are producers in a food chain?

Back

Producers are organisms, like plants, that make their own food through photosynthesis.

Front

What are consumers in a food chain?

Back

Consumers are organisms that eat other organisms for energy, such as animals.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organisms and recycle nutrients back into the soil.

Front

What do animals release that plants need?

Back

Animals release carbon dioxide, which plants use to make their food.

Front

What is the carbon dioxide-oxygen cycle?

Back

The carbon dioxide-oxygen cycle is the process where plants take in carbon dioxide and release oxygen, while animals do the opposite.

Front

What happens to organisms after a fire in an ecosystem?

Back

Organisms that rely on plants for food must find new sources of energy after a fire.
