- All the living or recently living parts of an ecosystem
-The non living parts of an ecosystem that organisms need to survive
-Hard part of the Earth's surface (Includes rock and oil)
-Liquid part of the earth's surface (Includes salt water oceans, freshwater lakes, rivers)
-Layer of gasses above Earth's surface (Including air)
-Living part of Earth's surface (Not separate from other abiotic spheres; includes life in soil, water, and air)
- -Chemicals needed by living organisms to survive.
- -Cycled through Earth's spheres.
- -The process of adding nitrogen or phosphorus to an ecosystem
- - Adding these substances will push the ecosystem beyond the normal nutrient cycle and beyond sustainability
- -The conversion of solar energy to chemical energy (To be used as food)
- (In the presence of light) Carbon dioxide + water --------------> Glucose + Oxygen (Chlorophyll is needed)
-Categories of organisms defined by how the organisms gain energy
-The total mass of living organisms in a defined group or area
-A measure of the amount of energy or biomass transferred from one trophic level to the next higher trophic level
-A process in which materials especially toxins, are ingested (absorbed) by an organism at a rate greater than they are eliminated
-Is the increase in the concentration of a toxin as it moves from one trophic level to the next
-The most common and efficient method for extracting the energy from glucose
Glucose + Oxygen -------> Carbon dioxide + Water + Energy
-A process that releases energy from organic molecules
-Atmospheric gases that prevent heat from leaving the atmosphere, thereby increasing the temperature in the atmosphere
-The warming of Earth as a result of greenhouse gasses
-Rain, snow, or fog that is unnaturally acidic due to gases in the atmosphere which react with water to form acids
