Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organisms, returning nutrients to the soil.

Front

How do plants primarily obtain the materials they need for growth?

Back

Plants obtain materials for growth from air and water.

Front

How do animals contribute to the movement of matter in an ecosystem?

Back

Animals contribute by consuming plants and other animals.

Front

What is the relationship between plants, animals, and decomposers in an ecosystem?

Back

They form a cycle of energy and matter transfer.

Front

Which of the following is NOT a source of materials for plant growth?

Back

Sunlight is NOT a source of materials for plant growth.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the primary source of energy for most ecosystems?

What are producers in an ecosystem?

Back

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

Front

What are consumers in an ecosystem?

Back

Consumers are organisms that eat other organisms for energy.

Front

What is a food chain?

Back

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