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

Which part of the plant absorbs carbon dioxide?

Back

The leaf absorbs carbon dioxide during photosynthesis.

What do plants produce during photosynthesis?

Back

Plants produce oxygen and glucose during photosynthesis.

Front

What is a food chain?

Producers are organisms, like plants, that make their own food using sunlight.

Front

What role do consumers play in a food chain?

Back

Consumers are organisms that eat other organisms for energy.

Front

What are decomposers?

Back

Decomposers are organisms that break down dead plants and animals, recycling nutrients back into the soil.

Front

How do animals and plants interact in the carbon dioxide-oxygen cycle?

Back

Plants produce oxygen that animals need to breathe, and animals produce carbon dioxide that plants need for photosynthesis.

Front

What is an example of a primary consumer?

Back

An example of a primary consumer is a grasshopper, which eats plants.

Front

What is an example of a secondary consumer?

Back

An example of a secondary consumer is a frog, which eats insects like crickets.
