Where Things Live
Living things need a place to live and grow.

Слайд 3

Fish live in water.

Слайд 4

Birds live in trees and fly through the air.

Слайд 5

Plants grow where there is soil, water and sun.

Слайд 6

Main Idea and Details

Слайд 7

ENVIRONMENT
The living and nonliving things that surround a living thing make

up its environment.

Слайд 8

What do living things get from their environments?
Many living things share

their environments and its resources.
Food
Water
Oxygen
Space

Слайд 9

Parts of an Ecosystem
An ecosystem is made up of all the

living and nonliving things in an environment.

Слайд 10

Different types of organisms live in an ecosystem.
A group of organisms

of the same kind living in the same place is a population.

Слайд 11

All the population that live in an ecosystem at the same

time form a community.

Слайд 12

All members of a community live in the same ecosystem but

they do not all live in the same part of the ecosystem.

Слайд 13

Where Plants and Animals Live
Habitat is a place where plants and

animals lives.

Слайд 14

It is a place where they can meet their needs. Animals get

food, water, and shelter from their habitat,

Слайд 15

Organisms 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.

Use the following tree map to write a lesson summary.

Слайд 18

What are some types of ecosystems?

Слайд 19

Types of Ecosystems
Deserts are very dry ecosystems.
Desert plants and animals can

survive with very little water.

Слайд 20

Desert 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 21

Grassland 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 22

Plants
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.

Слайд 23

Saltwater Ecosystems
Saltwater ecosystems are oceans.
Oceans cover about three –fourths of Earth’s

surface, so there are more saltwater ecosystems than any other.

Слайд 24

Sharks, sea turtles, corals and octopus are all ocean animals.
So are

whales and seals.

Слайд 25

Freshwater 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 26

Forest Ecosystems
Forest are ecosystems in which many trees grow.

Слайд 27

Tropical 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 28

Deciduous 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.
