What is a food web?

Back

A food web is a complex diagram showing how energy and matter flow between organisms in an ecosystem.

Front

How are food webs different from food chains?

Back

Food webs show multiple interconnected food chains, while food chains show a single path of energy flow.

Front

What do the arrows in a food web represent?

Back

The arrows show the direction of energy and matter transfer, from prey to predator.

Front

What is the role of producers in a food web?

Back

Producers, like plants, create energy-rich food through photosynthesis and serve as the base of the food web.

Front

What is the role of primary consumers in a food web?

Back

Primary consumers eat producers and transfer energy to higher levels of the food web.

Front

What is the role of secondary consumers in a food web?

Back

Secondary consumers eat primary consumers, transferring energy further up the web.

Front

What is the role of decomposers in a food web?

Back

Decomposers break down dead organisms, recycling matter back into the ecosystem.

Front

How does energy flow through a food web?

Back

Energy flows from producers to consumers and eventually to decomposers, with some energy lost as heat.

Front

Why are food webs important for understanding ecosystems?

Back

They show the interconnected relationships and dependencies between organisms.

Front

What happens if one species is removed from a food web?

Back

It can disrupt the balance, affecting other species and the flow of energy and matter.
