Answer to Question 1

Physical and biological factors in the environment determine the location and composition of
a community. Physical factors such as temperature, pressure, salinity, and the degree of force
exerted by waves or currents affect the success of an organism. Seaweeds adapted to cold
water usually cannot survive prolonged exposure to abnormally warm water, and lower-thannormal
salinity can dangerously disrupt the fluid balance of most marine invertebrates.
Biological factors are influences on an organism by members of its own population or other
populations, in its own or other communities. Biological factors include crowding, predation,
grazing, parasitism, shading from light, generation of waste substances, and competition for
limited oxygen.
