Unit 1 Review

residence time

the period of time spent in a particular place

reservoir

where a substance is stored

source

where carbon comes from

example of mutualism

clownfish and sea anemones

sink

where carbon goes

example of commensalism

bird nesting in a tree

denitrification

process of changing nitrates/ites to atmospheric nitrogen

desert

a biome with temperatures of -3.9C to 38C; 10 inches of rain per year

nitrogen fixation

the process of converting atmospheric nitrogen to ammonia

ammonification

process of decomposers turning nitrates/ites to ammonia

example of parasitism

ticks in humans

assimilation

process of nitrates/ites being used by plants

where is the largest nitrogen reservoir

atmosphere

where is the largest carbon reservoir

sedimentary rock

tropical rainforest

a biome with temperatures of 20C - 25C; 79-394 inches of rain per year

nitrification

process of changing ammonia to nitrates/ites

difference with phosphorus cycle

it's a lot slower and doesn't have an atmospheric phase

gross primary productivity

total amount of energy produced by producers

savanna

a biome with temperatures ranging 20C-30C; 10-30 inches of rain per year

how much water is drinkable

1%

tundra

a biome with temperatures of -40C - 18C; 6-10 inches of rain per year

net primary productivity formula

NPP=GPP-respiration

productivity unit

kcal/m^2/yr

where is light absorbed in water

red - 1m
blue - 100m

grassland

a biome with temperatures of -20C to 30C; 20-35 inches of precipitation

cultural eutrophication

too many nutrients in a reservoir caused by humans

estuaries

a marine biome where freshwater and saltwater mix. high biodiversity

eutrophication

too many nutrients in a reservoir

temperate deciduous forest

a biome with temperatures of -30C to 30C; 30-59 inches of rain per year
