What is an ecosystem?
a community of living things and their abiotic factors in an environment.
what is a food chain
linear sequence of energy transfers between organisms
what are trophic levels
different levels of a food chain
Q8: What is biodiversity, and why is it important?
the different kinds of life forms found in an area high biodiversity increases ecosystem stability and resilience to changes.
what is the carbon cycle
oposite of nitrogen cycle, The carbon cycle is the process by which carbon is exchanged between the atmosphere, organisms, and the Earth, including processes like photosynthesis, respiration, and decomposition.
TSMTE
troposphere, stratosphere, mesosphere, thermosphere, and exosphere
water cycle CTEPSG
condensation transpiration evaporation percipitation, surface run off, ground water
ways humans influence water cycle
damming rivers for hydroelectricity, using water for farming, deforestation and the burning of fossil fuels.
photosynthis equation
6CO2 + 6H2O → C6H12O6 + 6O2
nitrogen forms
inorganic (e.g., ammonia, nitrate) and organic (e.g., amino and nucleic acids) forms
nitrogen fixation
the process by which nitrogen is taken from its molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other biochemical processes.
why is fertalization harmful
release of harmful greenhouse gases into the atmosphere and the eutrophication of our waterways
lithosphere
all the surface of the earth above the mantle
healthy soil
micro organismes fungi = less erosion equal amounts of silt sand and clay
hydrosphere
all the water on earths surface
natural hydro
found in a variety of types of soil and rocks
artificial hydro
man made
atmosphere
enevelope of earths gasses
atmospher does?
gives oxygene for life and contains carbon for photosynthisis the trapped gas traps heat from the sun for teperature.
