How do producers and consumers interact in an ecosystem?

Back

Producers, like plants, create energy through photosynthesis, which is then consumed by herbivores (primary consumers), and subsequently by carnivores (secondary consumers).

Front

What role do decomposers play in an ecosystem?

Back

Decomposers, such as fungi and bacteria, break down dead organisms and waste, recycling nutrients back into the ecosystem.

Front

Organism

Back

One individual of a species.

Front

How do producers contribute to an ecosystem?

Back

Producers, such as plants, contribute to an ecosystem by converting sunlight into energy through photosynthesis, providing food for other organisms.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organisms and waste, recycling nutrients back into the ecosystem, which supports the growth of producers.

Front

What is the role of consumers in an ecosystem?

Back

Consumers are organisms that obtain energy by feeding on other organisms or organic matter, playing a crucial role in transferring energy through the ecosystem.

Front

How does energy flow in an ecosystem?

Back

Energy flows in an ecosystem through a food chain, starting from producers who capture energy from the sun, to consumers who eat the producers, and finally to decomposers who break down dead organisms.
