Food Webs and Biodiversity


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

Consumer

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.
