Abiotic Factor		Organisms, such as fungi and bacteria, that break down and absorb nutrients from dead organisms
Acid Rain		Interaction among organisms that require the same resources
Adaptive radiation		Nonliving parts of an organism's environment;temperature, moisture, light and soil are all examples
Artificial selection		The exchanging of chemical elements between organisms and the abiotic environment
Autotroph		Heterotrophs in a biotic environment that feed on other organisms or organic waste
Biochemical cycle		Organisms that use energy from the sun or energy stored in chemical compounds to manufacture their own nutrients
Competition		Rain, snow, sleet, or fog with a pH below 7; causes deterioration of forest, lakes, statues, and buildings.
Comsumers		Process of breeding organisms with specific traits in order to produce offspring with the same trait
