What is a producer in an ecosystem?

Back

A producer is an organism that can make its own food, typically through photosynthesis, and serves as a source of energy for other organisms.

Front

What is a consumer in an ecosystem?

Back

A consumer is an organism that obtains energy by eating other organisms, including plants and animals.

Front

What is a decomposer?

Back

A decomposer is an organism that breaks down dead organisms, non-living material, or waste, recycling nutrients back into the ecosystem.

Front

How do plants and animals interact in the carbon cycle?

Back

Plants produce and release oxygen that animals need for respiration, while animals produce carbon dioxide that plants use for photosynthesis.

Front

What happens to a rabbit population if the fox population decreases?

Back

The rabbit population would likely increase due to reduced predation.

Front

What role do snakes play in a food web?

Back

Snakes are consumers that obtain energy by eating other animals, such as frogs or rodents.

Front

What is the primary source of energy for most ecosystems?

Back

The primary source of energy for most ecosystems is the sun, which is harnessed by producers through photosynthesis.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs are organisms that produce their own food (like plants), while heterotrophs are organisms that consume other organisms for energy.

Front

What is an example of a primary consumer?

Back

An example of a primary consumer is a herbivore, such as a rabbit, that eats plants.

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers are crucial for breaking down dead matter and recycling nutrients, which supports plant growth and overall ecosystem health.
