The living things in an ecosystem are called a… COMMUNITY
A HABITAT is the physical part of the ecosystem.
The HABITAT provides resources like food and shelter to the organisms.
There are three types of members in every community. Producers Consumers Decomposers
Producers A living that can make its own food. To make their own food, producers need: Sunlight Water Carbon Dioxide
Examples of producers Algae Seaweed Grass Plants Trees
A producer can be as small as a algae or as large as a redwood tree.
Consumers A living that can not make its own food and must eat other living things.
If you consume food (eat), you are a consumer! We are all consumers!

Kinds of Consumers Herbivore An animal that eats only plants, or producers. Examples: Deer Rabbits Elephants Pandas Horses Cows
Kinds of Consumers Carnivore A an animal that eats only other animals. Examples: Sharks Lions Tigers Wolves Frogs
Kinds of Consumers Omnivore An animal that eats both plants and other animals. Examples: Pigs Raccoons Chickens Sea turtles
There are three types of members in every community. Producers Consumers Decomposers
Decomposers A living that feeds on the wastes and on the remains of dead plants and animals.
Decomposers break down wastes into nutrients. How do decomposers work? When plants and animals die, decomposers break down their bodies and return the nutrients into the soil. Nutrients: substances that are taken in by living things to help them grow.
How do decomposers work? By eating the plants, animals get the nutrients Plants take in nutrients through their roots Soil contains many nutrients
