Ecosystem Ecology Biogeochemical Cycles- the flow of important elements through the ecosystem. Hydrologic cycle-mainly an abiotically-driven cycle. Reservoirs-ocean, air, groundwater, glaciers Assimilation-plants absorb water from the soil, animals drink water and eat organisms Release-transpiration, evaporation, etc. Carbon cycle-mainly biotically-driven and tied to atmospheric CO2 levels that cause the greenhouse effect Reservoirs-atmosphere, fossil fuel, peat, organic material (like cellulose) Assimilation-photosynthesis, animals eating plants and each other Release-respiration and decomposition Nitrogen cycle-also a biotically driven cycle dependent heavily on bacteria Reservoirs-atmospheric N2, soil (nitrates, nitrites, ammonia) Assimilation-nitrogen fixation by bacteria, nitrification by bacteria Release- decomposition of dead organisms and animal waste
Which cycle is most affected by human combustion of fossil fuels? Biotic or Abiotic Impact Organisms Into ATM Out of the ATM Water Carbon Nitrogen Which cycle is most affected by human combustion of fossil fuels? When farmers cycle crops they often replace crops such as corn with soybeans. Based on what you know about cycles explain why?
smallest living thing living, growing, dividing the base of all life In your notes, write a haiku about each cycle: Water, Carbon, Nitrogen We will record on larger paper and share in 15 minutes. Remember syllables should be 5/7/5 By Owen Ulrich smallest living thing living, growing, dividing the base of all life
