DO NOW You may have heard the concept that in nature everything is connected. In your EcoLog answer the following questions: What does this mean? List 2 examples Everything is connected = EU – today the sparrow, tomorrow it may be you

Defining an Ecosystem Ecosystem = all of the organisms living in an area together with their physical environment interactions between living and nonliving components of the environment Ecosystem = I could also define ecosystem as…

Defining an Ecosystem Living (biotic) and Nonliving (abiotic) How do you define living and nonliving factors? Living (biotic) Nonliving (abiotic)

Biotic vs. Abiotic – What’s More Important? Groups 1, 2, and 3 (period 1/2) and Groups 1 and 2 (period 5/6) = List at least 8 biotic factors found in ecosystems. Rank them in order of importance and be prepared to defend your ranking. Groups 4, 5, and 6 (period 1/2) and Groups 3 and 4 (period 5/6) = List at least 8 abiotic factors found in ecosystems. Rank them in order of importance and be prepared to defend your ranking.

DO NOW In your EcoLog, describe how factors in the ecosystem below interact

Ecological Organization - Population Population = organisms of the same species living together in a given location

Ecological Organization - Community Community = all of the different populations in a given location interacting with each other Does not include abiotic factors

Ecological Organization - Ecosystem Ecosystem = all of the different communities in a given location interacting with each other

Ecological Organization - Biome Biome = a large region characterized by a specific type of climate and certain types of plants and animals

Ecological Organization - Biosphere Biosphere = every living and non-living thing on the planet (portion of the Earth in which life exists)
