All organisms must interact with both living (Biotic) and the nonliving (Abiotic) things that surround them

3. Ecology-Abiotic Factors
Abiotic-are non-living things that are part of the environment that affects living organisms and the ecosystems.
Examples: Soil-water-air-temperature-sunlight-wind-weather- landforms-lightening-etc…….

4. Ecology-Biotic Factors

8. Community

An ecosystem is made up of plants, animals, microorganisms, soil, rocks, minerals, water sources and the local atmosphere interacting with one another

10. Biomes
A major ecological community of organisms adapted to a particular climatic or environmental condition on a large geographic area in which they occur.

11. Biosphere
the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere.

12. Levels of Organization
Cells – tissues – organs – organ systems – organisms – population – community – ecosystem – biosphere
