Interactions In Ecosystems

Ecosystem- the interaction between living and non-living factors in an area. Some examples of different ecosystems are ponds, forests, rivers, deserts, etc.

Ecosystem- the interaction between living and non-living factors in an area. BIOTICABIOTIC

Ecosystem-the interaction between biotic and abiotic factors in an area. Biotic - everything that is living, or that was living at some point, in an ecosystem. Abiotic - everything that is non-living in an ecosystem.

Biotic or Abiotic??

Biotic or Abiotic? REMEMBER!! Even if something is not alive now, if it was alive at some point then it is BIOTIC!!

Name the biotic and abiotic factors in the picture: Biotic: shrubs Abiotic: air/wind rock sun

Name the biotic and abiotic factors in the picture: Biotic: trees shrubs dead wood Abiotic: water snow air/wind sun soil

Name the biotic and abiotic factors in the picture: Biotic: flowers lilly pads frogs fish grass Abiotic: water rock air/wind

Environmental changes: Small changes to the environment can have a HUGE affect on an ecosystem! Can you think of any examples?
