 In the food chain Sun → grass → rabbit → fox, which organism is the producer?

Grass is the producer because it makes its own food using sunlight.

How can sunlight help a plant make its own food?

Plants use sunlight during photosynthesis to make food from air and water.

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

A food chain shows one path of energy flow, while a food web shows many connected food chains.

300

Why are decomposers important in a food web?

Decomposers recycle matter back into the soil so plants can use it again.

Where does the energy in an animal’s food originally come from?

The energy in an animal’s food originally comes from the sun.
