Cellular Respiration |
A process that breaks down carbohydrates and other energy-rich products to prodice atp |
Found in the Mitochondria |
|
Photosynthesis |
The process of using the sun's energy to convert carbon into carbohydrates. (Sugar and starches) |
|
|
Primary consumers |
Organism that obtains energy by eating plants. |
Also called herbivores. |
|
Producers |
Organisms that make their own food. |
Also called autotroph. |
|
Secondary Consumers |
Organisms that eat primary consumers. |
|
|
Albedo |
Percentage of incoming solar radiation reflected by a surface. |
|
|
Chemosynthesis |
Process which fungi/bacteria use chemical nutrient energy to chemically convert carbon to carbohydrates without sunlight. |
|
|
Decomposers |
Organisms that eats dead plants and animal matter/ waste to obtain energy. |
|
|
Biomass |
Total dry mass of all living and non living organisms in a population, area/ other unit being measured. |
|
|
Food Chain |
A linear pathways which food is transfered from producers to primary consurmers & higher trophic levels. |
|
|
Food Web |
A model that shows the connections among food chains in an ecosystem. |
|
|
Pyramid of Biomass |
Schematic representation of the relative amount of biomass at each trophic level. |
|
|
Pyramid of Numbers |
Schematic representation of the relative numbers of organisms at each trophic level. |
|
|
Pyramid of Energy |
Schematic representation of the relative amount of energy at each trophic level. |
|
|
Adhesion |
Molecular attraction between two substances or bodies. |
For example the attraction between water & the surface of a glass tube. |
|
Acid deposition |
Process by which sulfur & nitrogen emissions undergo chemical change in the atmosphere & are deposited in the environment as dry particles & gases, or as wet acid precipitation, rain, snow, fog. |
|
|
Algal Bloom |
Rapid overgrowth pf algae in a body of water, usually resulting from high concentration of nitrate & phosphate; can result in deoxygenation of water when algae die, causing death of aquatic plants & animals. |
|
|
Ammonification |
Production of ammonia/ammonium products via breakdown of organic matter by decomposers. |
|
|
Biogeochemical Cycles |
The cyclical route taken by water & other chemical nitrients through all biotic and abiotic components of the biosphere. |
|
|
Cohesion |
Intermolecular force that holds molecules of liquids/ solids together. |
Example: the attraction of water molecules to each other resulting in surface tension. |
|
Denirification |
Conversion of nitrate/nitrite to nitrogen gas by bacteria in soil. |
|
|
Evapotranspiration |
Combined evaporation and transpiration of plants in a terrestrial area. |
|
|
Hydrologic Cycle |
Cycle of evaporation & condensation of water that determines the circulation of water through the atmosphere and biosphere also known as the water cycle. |
|
|
Hydrogen Bond |
Weak bond that involves sharing an electron between a slightly positive hydrogen atom and a slightly negative atom, such as oxygen/nitrogen, typically in another molecule. |
|
|
Metabolic Water |
Water created inside a living organism through their metabolism, by oxidizing energy - containing substances in their food. |
|
|
Productivity |
The rate at which organisms produce new biomass. |
|
|
Polar |
Refers to a molecule with an uneven charge distribution. |
|
|
Rapid Cycling of Nutrients |
Quick movements of nutrients through nutrient reservoirs, such as organisms, soil, air & water. |
|
|
Slow Cycling of Nutrients |
Long-term storage of nutrients in nutrient reservoirs, such as fossil fuels deposits, nutrients stored in these reservoirs are unavailable for long periods of time. |
|
|
Stomatolites |
Fossilzied sedimentary struture formed from ancient bacteria, iron bands present in same stromatolites provide evidence oxygen formation in earths past. |
