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 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 role do producers play in a food chain?

Back

Producers, like plants, create their own food through photosynthesis and are the first link in a food chain.

Front

What are decomposers?

Back

Decomposers are organisms, like fungi and earthworms, that break down dead plants and animals, returning nutrients to the soil.

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 take in oxygen and release carbon dioxide.

Front

Give an example of a food chain.

Back

An example of a food chain is: Grass → Rabbit → Fox.

Front

What is the main energy source for photosynthesis?

Back

The main energy source for photosynthesis is sunlight.

Front

How do animals depend on plants?

Back

Animals depend on plants for oxygen and food.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for plants to convert carbon dioxide and water into glucose and oxygen.

Front

What do plants produce during photosynthesis?

Back

Plants produce glucose (food) and oxygen during photosynthesis.
