Parts of Ecosystems
What are nonliving parts of ecosystems?
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
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 Earth’s
surface. It is made up of:• Rocks• Minerals• Organic matter
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.
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
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
What are nonliving parts of ecosystems?
Ecosystems are made up of living and
nonliving parts?
Different ecosystems have different light, soil, water, and temperature
conditions?
The nonliving parts of an ecosystem determine which plants and animals can live
there.
Author Questions
• What are some nonliving parts of an ecosystems?– Water– Air– Soil– Light– temperature
Author Questions
• What conditions would you find in a polar ecosystem?– Covered in ice– Temperatures are very low– During half the year there is little or no
sunlight.
Parts of Ecosystems
What are living parts of ecosystems?
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?
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.
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.
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.
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.
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.
Summarize
What are living parts of
ecosystems?
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.
Different parts of a ecosystem have different conditions. Organisms thrive in conditions that best
meet their needs.
Author Questions
• Explain why forest ecosystems support so many kinds of plants and animals. – Forest ecosystems provide the right
conditions for many living things.
Author Questions
• What factors determine the plants and animals that live in an ecosystem?– Temperature– Water– Sunlight
Author Questions
• How can conditions vary within a terrarium?– A rock under a heat lamp can be dry and
warm.– Soil under a piece of driftwood can be moist
and cool.

What are some roles of living things?
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.
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 anemone’s tentacles.
– The Egyptian plover and the crocodile• The Egyptian plover cleans the crocodile’s teeth
while getting a meal.
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.
What are some roles of living things?
• Plants are producers..
