WHAT ARE ECOSYSTEMS?
Where Things Live

Living things need a place to live and
grow.
Fish live in water.
Birds live in trees and fly through
the air.
Plants grow where there is soil,
water and sun.
Main Idea and Details
Living things need
a place to live
and grow.
Fish live in water.
Birds live in trees
and fly in the air.
Plants grow where
there is soil, water
and sun.
ENVIRONMENT

The living and
nonliving things that
surround a living
thing make up its
environment.
What do living things get from their
environments?

Parts of an Ecosystem

An ecosystem is made up of all the living
and nonliving things in an environment.
Different types of organisms live
in an ecosystem.
A group of organisms
of the same kind
living in the same
place is a
population.
All the population that live in an
ecosystem at the same time form a
community.
All members of a community
live in the same ecosystem but
they do not all live in the same
part of the ecosystem.
Where Plants and Animals
Live
Habitat is a place where plants
and animals lives and it gets all
that it needs to live.
It is a place where they can meet
their needs.
Animals get food, water, and shelter
from their habitat,
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.

Lesson 2
What are some types of
ecosystems?
Types of Ecosystems


Deserts are very dry
ecosystems.
Desert plants and
animals can survive
with very little water.
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.
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.
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.
Saltwater Ecosystems


Saltwater ecosystems are oceans.
Oceans cover about three –fourths of
Earth’s surface, so there are more
saltwater ecosystems than any other.
Sharks, sea turtles, corals and
octopus are all ocean animals.
So are whales and seals.
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.
Forest Ecosystems
Forest are ecosystems
in which many trees
grow.
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.
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.
Drawing Conclusions

Suppose all the plants in one ecosystem
died.
What do you think would happen to that
ecosystem?
Why?

Enough rain for trees to grow. They
lose their leaves in the fall.

Choose an organism.
Make a drawing of it.
Include the following details:
Name the type ecosystem in which it lives
List the habitat(definition), population(drawing)
and community(drawing) for the organism you
chose.
List if it’s a producer, consumer(which type if
consumer) or decomposer.
Create a 1 food chain that your organism would
be in.
