-
ecosystem
all the interacting parts of a biological community and its environment
self sustaining
supportinig
-
sustainable ecosystem
an ecosystem that us capable of of withstanding pressure and giving support to a variety of organisms
can survive when something is changed/ removed
-
biotic
all living parts of an ecosystem
anything that is alive or is recently deceased
-
abiotic
all the non living parts of an ecosystem
rocks, soil
-
lithosphere
- the hard part of the earths surface
- stome soil sand
-
hydrosphere
- the part of the earth covered in water
- oceans rivers lakes
-
atmosphere
- the layer of gases above of earths surface
- nitrogen oxygen water vapor
-
biosphere
- the living part of the earths surface
- living stuff
-
nutrients
- a chemical that is is essential to living things and is cycled through an ecosystem
- never lost, just moved.
-
eutrophication
- a processes in which nutrient levels in an aquatic ecosystem increase, leading to an increase in the population of the primary producers
- fertilizer and algae
-
photosynthesis
a process that changes solar energy into chemical energy
carbon dioxide+water- -glucose +oxygen
-
trophic levels
- a category of organisms that is defined by how the organisms gain energy
- plant,bug,bird,bigger bird
- 1000,100,10,1
-
biomass
the total mass of of living organisms in a defined area
-
trophic efficiency
- a measure of the amount of energy of biomass transferred from one trophic level to the next higher level
- how much is passed on on (10%)
-
bioaccumulation
a process in which an organism ingests materials, especially toxins, faster than they can eliminate them
-
bio magnification
a processes in which the concentration of ingested toxins increases as it moves from one trophic level to the next
-
cellular respiration
- a process that releases energy from organic molecules, especially carbohydrates, in the presences of oxygen
- glucose+oxygen--carbon dioxide+water
-
fermentation
- a process that releases energy from organic molecules, especially carbohydrates, in the absence of oxygen
- methane
-
greenhouses gasses
- a gas that prevents heat from leaving the atmosphere increasing the temperature of the planet
- global warming gases
- cows
- cars
-
green house effect
- the warming of the earth as a result of green house gases. which traps some of the energy that would otherwise be lost.
- global warming
-
acid precipitation
- rain snow of fog that is of unusual high pH, under5.6 as a result of gases in the atmosphere reacting with water vapor to form acid.
- bad
- 3.6-5.6 pH
