habitat and niche Flashcards
location in the natural ecosystem an organism resides in
habitat
encompasses the geographic location plants or animals live in, combined with varying nonliving or abiotic features
habitat
habitat is made of :
physical and biotic environment
examples of physical environment
soil
range of temperature
availability of light
moisture
example of biotic environment
availability of food
presence of predators
in a habitat, an organism must find:
food
water
shelter
space
small-scale physical requirements of a particular organisms or population
microhabitat
small area which differs somehow from the surrounding habitat. its unique conditions may home to unique species that may not be found in the large region
microhabitat
examples of microhabitat
a clump of grass
a fallen log
stone microhabitat
space between rocks
a flower
a tree
habitat of sufficient extent to present considerable variations of environment, contain varied ecological niches, and support a large and usually complex flora and fauna
macrohabitat
examples of macrohabitat
forest
grassland
streams
rivers
ponds
lakes
places that receive more rain than desert but less precipitation than forests
grassland
animals living in grassland
wolves, coyotes, swift, foxes, leopards, hyenas, badgers, snakes, etc.

other different kinds of habitats
fresh water
lakes
marine
savanna
intertidal zone
estuary
tundra
swamp
it is an organism’s role or job in the ecosystem
niche
biotic factors that help define a niche
food source and predators
