5L22 Classify Organisms (Producer, Consumer, Decomposer)

Front

What is a producer?

Back

A producer is an organism that makes its own food using sunlight through a process called photosynthesis. Examples include plants and algae.

Front

What is a consumer?

Back

A consumer is an organism that cannot make its own food and must eat other organisms (plants or animals) for energy. Examples include animals and humans.

Front

What is a decomposer?

Back

A decomposer is an organism that breaks down dead plants and animals, returning nutrients to the soil. Examples include fungi and bacteria.

Front

How do producers benefit ecosystems?

Back

Producers turn sunlight into energy through photosynthesis and release oxygen into the atmosphere, which is essential for other living organisms.

Front

How do consumers benefit ecosystems?

Back

Consumers help regulate plant and animal populations and transfer energy through the food chain by eating producers and other consumers.

Front

How do decomposers benefit ecosystems?

Back

Decomposers break down dead organic matter, releasing nutrients back into the soil, which helps plants grow.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which producers use sunlight, carbon dioxide, and water to create glucose (sugar) and oxygen.

Front

What are herbivores?

Back

Herbivores are consumers that eat only plants. Examples include cows, rabbits, and deer.

Front

What are carnivores?

Back

Carnivores are consumers that eat only other animals. Examples include lions, hawks, and sharks.

Front

What are omnivores?

Back

Omnivores are consumers that eat both plants and animals. Examples include humans, bears, and pigs.
