area.

Ecosystem is derived from the Greek word oikos, for “house,”

eco-is the combining form meaning

“environment or habitat.”

An Ecosystem may be very small such as:

A backyard A pond A playground

Some may be very large like:

The deserts of Africa The rain forest of Brazil The saltwater oceans

                                                           

    

All ecosystems have the same parts:

Abiotic Factors Biotic Factors

Abiotic FactorsThe nonliving parts of an ecosystem.

They include water, minerals, sunlight, air, climate, and soil.

Biotic Factors

The living parts of an ecosystem.

They include animals, plants, fungi, protists, and bacteria.

All organisms of a species living in the same area

make up its population.

All the populations living in an area make up a

community.

Ecosystems

are made of

Habitats

Where Plants and Animals Live

Habitat is a place where plants and animals can meet their needs.

Animals get food, water, and shelter from their habitat.

Life in a Woodland Forest

A woodland forest is a habitat that gets enough rain and sunlight for trees to grow well.

When birds migrate in the fall they move to warmer places.

The four seasons of a woodland forest are: spring, summer, fall, and winter.

In the spring animals have their young, and leaves began to grow on trees.

In the summer animals find a lot of food, and the leaves are green on trees.

In the fall plant seeds stick to animals, and leaves on the trees began to change colors.

In the winter some animals go into a deep sleep, and most trees do not have any leaves.

Life in a Rain Forest

A rain forest is a habitat where it rains almost every day.

Animals use trees and plants for food and shelter.

Life in a Desert

A desert gets less rain in a year than most plants and animals need to live.

Many animals hide below ground or under rocks to keep cool.

Life in the Arctic

The Arctic is a very cold place, near the North Pole, where snow is on the ground for much of the year.

Plants grow low to the grow in the summer in the Arctic.

Animals migrate in the winter in the Arctic to find food.

Habitat What It Is Like

Woodland Forest

Enough rain for trees to grow

Rain Forest Rains every day and has many trees and plants

Desert Hot and dry

Arctic Very cold place with snow on the ground most of the year

Ecosystems contain Habitats with diverse plants and animals
