What are nonliving parts of ecosystems?

• An ecosystem is made up of all the living and
  nonliving things that interact in an area.
• Nonliving things in an area include
• Water
• Air
• Soil
• Sunlight

3
What are nonliving parts of ecosystems?

• Air
• Animals depend on oxygen to use food as energy.
• Plants depend on carbon dioxide to make food.
• Soil
• Soil is loose material that covers much of
  Earths surface. It is made up of
• Rocks
• Minerals
• Organic matter

4
What are nonliving parts of ecosystems?

• Organic matter
• is made of the remains of plants and animals.
• Help plants grow because it is rich in nutrients.
• Sunlight
• Plants and animals depend on sunlight.
• Plants need sunlight to make food
• Sunlight provides heat energy.

5
What are nonliving parts of ecosystems?

• Different Ecosystems have its own
• Amounts of light and water
• Range of temperatures
• Soil Types
• These conditions determine the kinds of living
  things that are able to survive there

6
What are nonliving parts of ecosystems?

• Polar Ecosystems
• Covered in ice
• Temperatures are very low
• During half the year there is little or no
  sunlight.
• Desert Ecosystems
• Daytime temperatures are very high
• Little rain falls
• Soil is poor and sandy

Summarize
Ecosystems are made up of living and nonliving
parts?
Different ecosystems have different light, soil,
water, and temperature conditions?
What are nonliving parts of ecosystems?
The nonliving parts of an ecosystem determine
which plants and animals can live there.

11
What are living parts of ecosystems?

• A living thing will survive only in an
  environment that meets its needs.
• An environment is everything that surrounds and
  affects a living thing.
• All living things in an ecosystem make up a
  community.
• A population is all the members of one kind of
  plant or animal in a community.

What are living parts of ecosystems?

• A rainforest is an area where it rains a lot.
• A tropical rainforests is located in a tropical
  climate where it is warm and humid.
• A temperate rainforest is located in a temperate
  climate where temperatures are usually warm.
• Trees tend to grow close together providing
  shelter and water for many kinds of plants and
  animals.

14
What are living parts of ecosystems?

• A prairie is a grassy land area with few or not
  trees.
• Prairies receive more rainfall than deserts, but
  less than forests.
• Winters are cold, and summers are hot.
• Grasses grow well here.
• Prairie ecosystems are home to animals that feed
  on grasses and their seeds.

15
What are living parts of ecosystems?

• New York City is located in a temperate zone
  which have cold wet winters and hot dry summers
  and is home to many living things.
• In wetland ecosystems water covers much of the
  land.
• Water plants and tiny algae live in the water
  which are food for fish, which in turn, are food
  for herons and other wading birds.

16
What are living parts of ecosystems?

• A terrarium is a model of an ecosystem.
• A heat lamp is used to model the Sun.
• Living things interact with each other and with
  nonliving parts.
• Conditions may vary in a terrarium.
• A rock under a heat lamp can be dry and warm.
• Soil under a piece of driftwood can be moist and
  cool.

17
What are living parts of ecosystems?

• Large ecosystems also have conditions that vary
  in different areas.
• Organisms thrive where conditions best meet their
  needs.
• In the ocean, conditions vary in a coral reef
  ecosystem.
• Some organisms meet their needs a the reef top
  near the ocean surface.
• Others live in deeper water.

18
Summarize
All the different populations of plants and
animals living in one area make up a community.
Every ecosystem has its own set of nonliving
conditions. Living things that live there are
suited to those conditions.
What are living parts of ecosystems?
Different parts of a ecosystem have different
conditions. Organisms thrive in conditions that
best meet their needs.

• What are some roles of living things?

23
What are some roles of living things?

• Living things are found in an ecosystems are
  interdependent.
• This means that living things depend on each
  other to meet their needs.

24
What are some roles of living things?

• Examples of interdependence
• The swollen acacia tree and a type of stinging
  ant.
• The ants get food from the plant and the plant
  gets protection from the ants.
• The sea anemone and the clown fish
• The sea anemone protects the clown fish while the
  clown fish cleans the sea anemones tentacles.
• The Egyptian plover and the crocodile
• The Egyptian plover cleans the crocodiles teeth
  while getting a meal.

25
What are some roles of living things?

• Everything has a role to play within its
  ecosystem.
• A producer is an organism that makes its own food
  through using the energy from the sun known as a
  process called photosynthesis.
