does temperature affect the temperature of organisms within the
water and their rate of growth and reproduction?
Most organisms that live in water
will have the same temperature within their bodies as the temperature
of the water that surrounds them.
Aquatic organisms have adapted over
time to survive and reproduce best within a narrow range of temperatures.
In general, as temperature increases an organism's activity and
growth rate increase. Associated with this increased activity is
an increased need for oxygen.
Reproductive systems are very sensitive
to temperature and, as a result, organisms tend to reproduce best
at a particular time of year. Reproduction of organisms tends
to change with the seasons and, therefore, is directly related to
the temperature of an organism's environment.
