What is Ecology?

• Ecology– Study of relationships among living organisms and

the interaction the organisms have with their environments

– Ecologists observe, experiment, and model using a variety of tools and methods

Abiotic vs. BioticBiotic Factors:– Living factors in an organism’s environment– Ex.

Abiotic Factors:Nonliving factors in an organism’s environment

Ex.

*Organisms depend on and adapt to survive in the abiotic factors present in their natural environment.*
