Слайд 7ENVIRONMENT
The living and nonliving things that surround a living thing make
up its environment.
Слайд 8What do living things get from their environments?
Many living things share
their environments and its resources.

Слайд 9Parts of an Ecosystem
An ecosystem is made up of all the
living and nonliving things in an environment.
Слайд 10Different types of organisms live in an ecosystem.
A group of organisms
of the same kind living in the same place is a population.
Слайд 12All members of a community live in the same ecosystem but
they do not all live in the same part of the ecosystem.
Слайд 14It is a place where they can meet their needs. Animals get
food, water, and shelter from their habitat,
Слайд 15Organisms and their Habitats
Some organisms can survive only in certain habitats.
For
example, a polar could not find the water it needs in a desert.

Слайд 19Types of Ecosystems
Deserts are very dry ecosystems.
Desert plants and animals can
survive with very little water.
Слайд 20Desert Plants
Desert plants, such as cactus, have thick stems that store
water.
The roots of a cactus lie just below the soil and spread far from the plant.

Слайд 21Grassland Ecosystems
Grasslands are dry, often flat areas of land that are
hot in the summer and cold in the winter.
They get more rain and snow than deserts but less that most other ecosystems.

Слайд 22Plants
The main plant in a grassland ecosystem is grass.
There
are not many bushes in the grassland.
Trees are found only by rivers and streams.
Trees are found only by rivers and streams.
Слайд 23Saltwater Ecosystems
Saltwater ecosystems are oceans.
Oceans cover about three –fourths of Earth’s
surface, so there are more saltwater ecosystems than any other.
Слайд 25Freshwater Ecosystems
Rivers, ponds, lakes and streams have fresh water.
Lakes and rivers
are closely tied. Some lakes are the source for some rivers. Important rivers, most often, originate from lakes. Some rivers end in lakes.
Since both rivers and lakes are freshwater and flow in and out of each other, they share similar characteristics and many species reside in both habitats.

Слайд 27Tropical Rain Forest
A tropical rain forest grows where it is hot
and wet all year long.
Animals such as jaguars and monkeys live there.

Слайд 28Deciduous Forest
What's A Temperate Deciduous Forest Like?
One of
the most interesting features of the temperate deciduous forest is its changing seasons.
The word "deciduous" means exactly what the leaves on these trees do: change color in autumn, fall off in the winter, and grow back again in the spring. This adaptation helps trees in the forest survive winter.

Слайд 29Drawing Conclusions
Suppose all the plants in one ecosystem died.
What do you
think would happen to that ecosystem?
Why?
Why?

Review
Desert
Rain Forest
Rains every day
and has many trees and plants
Hot and dry
Deciduous Forest
Enough rain for trees to grow. They lose their leaves in the fall.
Made up of rivers, ponds, lakes and streams and my water does not have much salt
Freshwater Ecosystems
Слайд 31Try this!

Write a descriptive paragraph
about it.
Include the following details:
Name of the ecosystem
Type of ecosystem: Characteristics
Animals and plants found their.
