These organisms use sunlight directly to make their own food.

Plants, algae, and some micro-organisms are these.

This picture or diagram demonstrates that there is more than one type of producer, consumer etc. in an ecosystem.

This type of chemical is in the soil due to rock erosion and is an important cycle in ecosystems.

These organisms cannot make their own food, so they eat producers to obtain energy.

A grasshoper is an example of this.

This is an illustration that demonstrates how energy moves in an ecosytem.

This element is in sugars, proteins, starches and other compounds that make up living things. It's important to both nonliving and living things.

These organisms that get energy by breaking down the remains of dead organisms.

An owl is an example of this.

This changes nitrogen in plants so they can absorb it.

The energy movement in an ecosystem begins with this.

A group of organisms that share similar characteristics and can reproduce among themselves.

A turkey vulture is an example of this.

Nitrifying bacteria helps to change this in plants into food that they can absorb through their roots.

Living organisms that eat only meat are called this.

What is the correct order of these ecosystem roles: Herbivores, Sun, Producers, Carnivores, Scavengers

Fungi are an example of these.

Less energy is available at the top or the bottom of the food energy pyramid in an ecosystem?

This is where carnivores get their energy.
