Habitat = The place an organism lives. Includes all the living and nonliving factors needed. Provides: Food/water Shelter Mates sunshine
Niche “Organism’s role in the ecosystem”… The huge amounts of dung and soil moved by these creatures serves to fertilize the soil, loosen the soil, and open up areas on the surface for grass to grow.
Components of an Ecosystem Biotic Factors All living or once living parts. Even dead and waste products. Abiotic Factors Nonliving parts Air, water, rocks, sand, etc.
Organism = Individual living thing ex – carpenter ant Species = group of organisms that can mate to produce fertile offspring. ex – carpenter ants
Population (1) = all the members of the same species that live in the same place at the same time.
Communities (2+) = a group of various species that live in the same place and interact with each other.
Ecosystem =Includes all of the abiotic and biotic factors in that local area!
Biome = a large region characterized by a specific type of climate and certain types of plant and animal communities. Ex = desert
Biosphere Part of the planet that contains these Biotic and Abiotic environments.
Organization review… Organism Population (1) Community (2+) Ecosystem (community + abiotic) Biome (ecosystem on a larger scale!) Biosphere ( Biomes on the planet)
