Energy
All Organisms Need Energy
 All
organisms in an ecosystem
need energy to live.
 Organisms
can be grouped by
how they get energy.
 Organisms
in an ecosystem are
grouped as producers,
consumers, or decomposers.

What Are Producers?

Producers are organisms that use
energy from the sun to make
their own food through a process
called photosynthesis.

A producer as an organism that
produces its own food.

Most producers are plants.

Examples of Producers


While most producers are plants,
algae and some bacteria are also
producers. Algae are common
producers in estuaries and marine
ecosystems.
The grasses, shrubs, and trees in a
meadow are examples of
producers. These types of
producers are common in
grasslands and forest ecosystems.
Consumers


Some organisms must get energy by eating
other organisms. These organisms are called
consumers.
Consumers can be organized into three
groups: carnivores, herbivores, and
omnivores.
Consumers
Carnivores
 Carnivores
are consumers that
eat only other animals.
 In
marine ecosystems, sharks,
walruses, seals, and octopuses are
common carnivores.
 In
land ecosystems, lions, wolves,
hawks, and eagles are common
carnivores.
Consumers
Herbivores
 Herbivores
are consumers that
eat only plants.
 Since
plants make their own food,
herbivores get energy from eating
these producers.
 In
a forest ecosystem, deer and
rabbits are common herbivores.
 In
a savannah ecosystem in Africa,
zebras and elephants are common
herbivores.
Consumers
Omnivores
 Omnivores
are consumers that
eat both plants and animals.
 Since
they can eat a variety of
organisms, omnivores can easily
adapt to changing environments.

 Pigs,
bears, raccoons, and
humans are examples of
omnivores.
