ecosystems
100
members of this all have similar characteristics, and are the same type of organism. They breed fertile offspring.
What is a species?
100
this amount of energy is all that ascends each trophic level
What is 10%?
100
this biome exists at very high altitude or near the polar regions, and is characterized by permafrost
What is tundra?
100
because of this, sediment from a mountaintop reaches all the way to the ocean
What is watershed?
100
these elements and compounds must be consumed and can be a limiting factor in their availability for a population
What are nutrients?
200
diffrerent species living in this interact.
What is a community?
200
this occurs in an area where no vegetation or soil life remains
What is primary succession?
200
this biome is near the equator, but doesn't get much rain
What is tropical dry forest?
200
cnsists of evaporation, transpiration, precipitation, and runoff, and even has its own dance
What is the water cycle?
200
where two ecosystems meet and interact
What is an ecotone?
300
A species or organism fits into this in its community with its role and use of resources.
What is a niche?
300
this organism has a large influence on its entire community, and could have drastic consequences if removed
What is a keystone species?
300
this is the typical mediterranean biome
What is chaparral?
300
it is added to the air by humans, then absorbed by the ocean, causing ocean acidification
What is carbon?
300
these organisms provide food for the entire rest of the community
What are primary producers?
400
this contains all living things on earth
What is the biosphere?
400
this could be caused by the loss of a keystone species
What is a phase shift?
400
the input of this loop is neutralized by its output
What is a negative feedback loop?
400
this process must be performed bu bacteria in order to transform an inert gas
What is nitrogen fixation?
400
the natural cycling of nutrients that we rely on
What are ecosystem services?
500
this describes the flow of nutrients and energy through an ecosystem
What is ecosystem ecology?
500
this exotic thing could change an ecosystem and dominate
What is an invasive species?
500
the release of moisture as air cools over mountaintops
What is rainshadow?
500
this process allowed people to create cheap fertilizer for soil by artificially performing an integral step of a biogeochemical cycle
What is the Haber-Bosch process?
500
these groups of organisms have been separated and are at a higher risk of extinction
What are metapopulations?
