What word do we use to describe the living parts of our environment? biotic
What are the 5 levels that the environment can be organized into? (from smallest to largest) organism population community ecosystem biosphere

How big is a biosphere? A biosphere includes the deepest portions of the oceans all the way up to the atmosphere where life exists.
How are populations and communities related? Several populations of species living and interacting in an area make up communities.
How do abiotic factors affect the environment? Example: When it rains, plants grow. As the plants grow, organisms have more food and shelter available. Example: When the temperature is very hot, organisms have to adapt= find shady tree, dig hole in the ground, spray mud on top of them...
Do biotic factors affect abiotic factors? Yes. Ex: grass roots hold sand dunes in place, free-swimming corral attach to rocks forming corral reefs (changing direction of water that must flow around the reef)
