abiotic and biotic factors

biotic

living things ( organisms, there waste, there remains, there nest, there features)

abiotic

non living things ( water, sun, temperatures, wind, air, minerals)

organisms

share ecosystems

limiting factors

restric the size of a population

tolerance range

species can only survive in tolerance range

terrestrial ecosystem

land based ecosystems (limited by temp, precipitation, and light)

aquatic ecosystem

water based( limited salt concentration, sunlight, oxygen, and nutrients)

influence of biotic factors

competition

predation

mutualism

parasitism

commensalism

competition

2 individuals feeding of the same resource ( can limit suply)

predation

1 individual feeds on another

mutualism

2 individuals benefiting from eachother

parasitism

1 individual feeds on a host organism

commensalism

one individual benefits from another org but that org didn’t benefit or get harmed

carrying capacity

the max population size that an ecosystem can sustain ( can cause fewer resources and overpopulation of predators

ecosystem

is all the living organisms and there environment in a region

photosynthesis

the process which the suns energy is converted into chem energy (only plants)
