Finding our Niche in Science 7 |
|
Every organism exists within a given NICHE in their ecosystem. This means that each organism has a role.
|
Roles of OrganismsProducers Living things that make their own food using air, light, soil and water.
Consumers Living things that use producers or other consumers to gain energy.
There are three specific kinds of consumers:
|
Scavengers Living things that gain energy by eating organisms that have already died.
Decomposers Living things that break down dead matter (plants and animals) and their waste.
Energy Cycles in the Ecosystem
Energy is transferred throughout the ecosystem, starting with the sun. As organisms consume their food, the energy is passed along.

Energy Pyramids are another way to represent data.
