What is the difference between a food chain and a food web?

A food web is the interacting and overlapping of all the food chains in an ecosystem.

400

Mushroom

400

How do organisms interact in a food web?

They depend on each other for food

400

How do plants absorb nutrients?

Through roots


500

Why is photosynthesis important for ecosystems?

It provides energy for consumers

500

What happens if one organism is removed from a food chain?

It can disrupt the balance of the ecosystem

500

What role do producers play in an ecosystem?

They provide energy for all organisms

500

Describe how energy is transferred in a food chain.

From producers to consumers to decomposers
