Matter and Energy in Ecosystems

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What are producers in an ecosystem?

Back

Producers are organisms that can make their own food through photosynthesis or chemosynthesis, such as plants and some bacteria.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organisms and waste, returning vital nutrients to the soil and making them available for use by plants.

Front

What is the primary source of energy for photosynthesis?

Back

The primary source of energy for photosynthesis is sunlight.

Front

What do plants take in from the air during photosynthesis?

Back

Plants take in carbon dioxide from the air during photosynthesis.

Front

What do plants release as a byproduct of photosynthesis?

Back

Plants release oxygen as a byproduct of photosynthesis.

Front

How do decomposers contribute to nutrient cycling in ecosystems?

Back

Decomposers contribute to nutrient cycling by breaking down organic matter, which releases nutrients back into the soil for plants to use.

Front

What is the relationship between photosynthesis and energy storage in plants?

Back

Photosynthesis allows plants to convert sunlight into chemical energy, which is stored in the form of glucose and other energy storage molecules.

Front

What is the difference between producers and consumers in an ecosystem?

Back

Producers create their own food through photosynthesis, while consumers obtain energy by eating other organisms.
