Presentation Transcript

Producers
Producers

  • Most are photosynthetic

    • Use light energy to produce food

  • Some are chemosynthetic

    • Use stored chemical energy to produce food

  • All producers are Autotrophic

    • Produce their own food for energy


Producers1
Producers

Plants

Algae


Consumers
Consumers

  • Heterotrophic

    • Consume other organisms as food for energy

  • Herbivores-eat only plants

  • Carnivores-eat only meat

  • Omnivores- eat plants and meat


Consumers1
Consumers

  • Detritivores-receive energy from dead organisms

  • Decomposers-responsible for decay and returning nutrients back into environment


Trophic level and energy pryamid
Trophic Level and Energy Pryamid

Each organism represents a trophic level on

the energy pryamid.

Plants

(Producers)


Energy transfer
Energy Transfer

Only 10% of the energy from one trophic

level is transferred to the next.


Food chain
Food Chain

Shows how each living organism obtains

food. What eats what.

Primary

Producer

Secondary

Consumer


Food web
Food Web

Many food chains connected together


Biodiversity
Biodiversity

The diversity of life. The different organisms

Found on the Earth.
