Mo2-L7a: How Does Energy Flow in an Ecosystem?
Key Concept
How Does Energy Flow in an Ecosystem?
Light energy is changed How does energy move from a producer to other
to food energy by a process organism?
called photosynthesis.
A few organisms are able to capture energy from
chemicals in the environment and make food by a
process called chemosynthesis.
Other organisms cannot capture energy from sun-
light or chemicals and must obtain their energy by
eating food.
Organisms that cannot make their own food using
the Sun must depend on organisms that can.
Hydrothermal sulfide
CO 2 Water
SUMMARY
How Does Energy Flow in an Ecosystem?
Sugar is formed
A producer changes the energy available in
Hydrothermal Vent the environment into food energy.
Producers change the energy
available in their environment
into food energy that they use
to live and reproduce.
