Cycles/Succession

Cycles and Succession

TermDefinition
Biogeochemical Cycles The ways in which an element—water, carbon, nitrogen, phosphorus-moves between its various living and nonliving forms and locations in the biosphere
Precipitation Water being released from clouds (rain, snow, sleet, hail)
Transpiration Water movement through the plants and released back into the atmosphere.
Evaporation Water turning to vapor form moving back into the atmosphere.
Condensation Water vapor collecting in clouds (condensing)
Accumulation Water collecting in large bodies of water (pond, lake, ocean)
Nitrogen fixing bacteria (Microbes) needed to change nitrogen gas into a useable form for plants.
Phosphorus element in rocks, only present in the ground to cycle
Photosynthesis Process where plants take in carbon dioxide and create oxygen and glucose
Cellular Respiration process where animals release carbon dioxide due to the input of glucose (food) and oxygen.
Fossil Fuels made from decomposing plants and animals: Coal, oil, natural gas (releases excess carbon)
Ecological Succession the CHANGE of an ecosystem over time.
Primary Succession Starts with rock, no life present
Secondary Succession Follows after a disturbance (fire, flood) Soil is present**
Pioneer Species The first plant species (lichen- primary; grass, secondary)
Climax Community The final, stable stage of succession (ex. forest; large trees)
Biotic Factors Living things; plants, animals, bacteria
Abiotic Factors Nonliving things; water, soil, rock
