10Th Grade Biology Ecology - Test Review

Front 1

define abiotic factors

Back 1

non living factors such as wind, sun and minerals

Front 2

define biotic

Back 2

living factors such as animals and plants

Front 3

explain how organisms, populations, communities, and ecosystem relate to each other

Back 3

organisms are in communites, populations, and ecosystems, while populations are in communites, communites are in ecosystems and they all consist of animals, plants, and bacteria and how they are categorize

Front 4

identify the shape of data in an expontential growth curve

Back 4

j-shaped

Front 5

identify the shape of date in a logistic growth curve

Back 5

s-shaped

Front 6

define limiting factors and list examples

Back 6

a resource that is necessary for the organism's survival but can only be found in a finite amount -- exp. food, water territory, mates

Front 7

define carrying capacity and descirbe how it looks on a graph

Back 7

the number of a population in a community that the area can support -- j-shaped: has ulimited food, habitat, water,a nd mates s-shaped: shot up so quickly and eventually will level off and/or drop

Front 8

define predator

Back 8

when a species eats another species not in its trophic level -- exp. hare and lynx

Front 9

draw predator-- prey graph and describe what the increases and decreases in populations could be caused from

Back 9

when a predator goes up in the graph prey goes down and once the prey go down predator go down and it repeats itself

Front 10

define producer, herbivore, and carnivore, and describe the the realtionship between them in a food chain

Back 10

producer: use photosynthesis to synthesize organic compounds - herbivore: are primary consumers who only eat plants - carnivore: secondary consumers who only eat meat -- the relationship between them is the producers are eaten by primary consumers that are eaten by secondary consumers
