tropical Biotic Abiotic determines the survival and growth of an organism and the productivity of the ecosystem in which the organism lives all the living things that interact in an ecosystem non-living things that shape an ecosystem climate

heterotrophs
decomposers Inteactions
competition
predation
symbiosis Mutualism
Commensalism
Parasitism Due to natural or human distrubances
Predictable changes over time
2 types An ecological process by which one community is replaced by another until a climax community develops. Primary succession - soil is destoryed and bare rock is exposed
Secondary succession - the soil is preserved pioneer species - the first species to move into an area of Primary succession (often lichen)
climax community - the final community that will exist in an ecosystem. Niche - the full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions. No two species can share the same niche in the same habitat What is its food?
How does it get food?
Is it food? To who?
What resources does it use?
What are its interactions?
