Biogeochemical Cycles
Plant sweat
Transpiration
List the 3 required components of an ecosystem
Producer, consumer, decomposer
All ecological pyramids have a base level of these
Producers
This is the organelle that photosynthesis takes place in
Chloroplast
Tundra
Fossil fuels are a sink in this cycle
Carbon
List the 3 required abiotic components of an ecosystem, not including light energy
These organisms are nature's recyclers
Decomposers
Thylakoid
Large, close to mainland
This cycle relies on bacteria to fix and "de-fix"
Nitrogen
A long term symbiotic relationship where one organism, a host, uses another for survival
Parasitism
Must eat something else to obtain their energy
Location of the Calvin Cycle
Stroma
HIPPO (habitat loss, invasive species, pollution, population growth, overharvesting)
Without this, none of the cycles would work
Interaction that benefits both species by providing each other with a needed resource
Mutualism
Direction of arrows in a food web/chain
Points towards the organism that is receiving the energy
Opposite of photosynthesis, releases carbon into the atmosphere via consumers
Cellular respiration
2 characteristics that measure level of biodiversity of an ecosystem
Species richness, species evenness
Ex: An egret follows along behind a cow as the cow kicks up the bugs in the grass. The egret eats the bugs.
Commensalism
The amount of energy on the 4th trophic level if there isi 870,560 kcal of energy in the 1st level
870.5 kcal
2 non-recycled final outputs of photosynthesis
Oxygen, glucose
Definition of a carbon sink
A reservoir that captures/absorbs/stores more carbon than it releases (at a certain point in time)
