Name a limiting factor of each of the following: taiga, tundra, deciduous forest.
taiga-- temperature, poor soil tundra-temperature, low vegetation, low biodiversity, water, coverage deciduous-- seasons because only 4-5 months of growing seasons

Almost all of the energy used by living organisms comes from where?
The Sun

Spiny succulent plants are most likely to be found in
deserts bruh

What factor controls the prey population?
# of predators

What would happen to the flow of materials if decomposers were removed from an ecosystem?
It would stop bruh

Distinguish between richness, abundance, and evenness in relation to biodiversity.
species richness is related to species diversity. It refers to the number of different species present in an environment. Species relative abundance is how many of each species. species evenness refers to how close in numbers each species in an environment are.

what does a predator-prey population graph look like?
alternating humps

Why do most food chains only have 3 -5 trophic levels?
10% rule – 10% of energy to next level

What is the tundra permafrost and how much does it change from season to season?
the permafrost is a thick permanently frozen layer – only a small portion thaws in summer and supplies moisture.

What do you call the community interaction between a bee and a flower? How about a vine on a tree?
Mutualism, commensalism
300
fundamental vs realized niche?
fundamental--- all potential "jobs" a species can have realized--- its actual job because its hard out there and there is competition bruh!

What is intraspecific exploitation? howbout that interspecific exploitation? give example of each
intra-within a species inter-between different species exploitation-competition thru depleting a common resource moose eatin all the grass so bunnys cant get any for inter moose eatin all the grass so other moose can get any and he will be the kind of da pack and get all the females for intra

Name 2 adaptations that allows animals who stay for the long cold taiga/ tundra winters to survive?
hibernate, store extra body fat, grow thick fur, burrow into the snow for insulation
500
What is the difference between genetic, species, and ecological diversity?
Genetic diversity – varies in the genetic make-up among individuals within a single species Species diversity – variety among the species or distinct types of living organisms found in different habitats of the planet Ecological diversity – variety of forests, deserts, grasslands, streams, lakes, oceans, wetlands, and other biological communities

Which of the two biomes (tundra or taiga) has the greatest variation in the daily sunlight through the year? Why?
tundra – angle of sun causes very long days in summer and very long nights in winter
500
Name the greenhouse gases and where are they found?
water vapor, carbon dioxide, methane, nitrous oxide, and ozone. found in da TROPOsphere my dude!

Breifly describe 5 of the biogeochemical cycles MWAHAHHAHA
CHNOPS---the flow of essential elements from the environment to living things and back to the environment Water cycle is a duh carbon reservoirs --- atmosphere (as carbon dioxide), fossil fuels, peat, organic material (cellulose) carbon release----plants and animals- decomposition and respiration Nitrogen reservoirs, nitrate, nitrite, ammonia soil stuff in soil nitrogen release---denitrificatiion, excretory systems, ammonification phosphorous reservoir---rocks, ocean sediments assimilation release--plants and animals release phosphorus when they decompose assimilation---plants absorb inorganic phosphorus
