How does temperature affect an organism?
Affects their rate of metabolism, some organisms cannot maintain a constant body temperature, some can't tolerate extreme temperatures,
2 of 6
How does the availability of nutrients affect an organism?
nutrients such as nitrates are essentials for the growth of plants/microorganisms, if there's a low amount they may not be able to survive

How do the amount of light affect an organism?
Plants require light for photosynthesis, plants grow slowly in low light intensities
