Producers, Consumers and Decomposers

Front

What is a producer?

Back

A producer is an organism that makes its own food using sunlight, water, and carbon dioxide, typically through photosynthesis. Examples include plants like cactuses and grass.

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 rabbits, hawks, and wolves.

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 earthworms and mushrooms.

Front

How do producers contribute to an ecosystem?

Back

Producers create food for themselves and other organisms, forming the base of the food chain and providing energy for consumers.

Front

What role do consumers play in an ecosystem?

Back

Consumers obtain energy by eating producers or other consumers, helping to transfer energy through the food chain.

Front

What is the role of decomposers in nutrient cycling?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil, which supports plant growth.

Give an example of a producer in a desert ecosystem.

Back

Cactuses are a primary producer in a desert ecosystem.

Give an example of a consumer in a grassland ecosystem.

Back

A bison is an example of a consumer in a grassland ecosystem.

Front

What happens to energy as it moves through a food chain?

Back

Energy decreases as it moves from producers to consumers, with each level using some energy for its own life processes.

Front

What is the difference between a herbivore and a carnivore?

Back

A herbivore is a consumer that eats only plants (e.g., rabbits), while a carnivore is a consumer that eats other animals (e.g., wolves).
