While it is true that living organisms
are profoundly affected by their
environment, it is equally important to
remember that many organisms are also
(5) capable of altering their habitat
significantly, sometimes limiting their
own growth. The influence of the
biological component of an ecosystem is
often greater in fresh waters that in
(10) marine or terrestrial systems, because
of the small size of many freshwater
bodies. Many of the important effects of
organisms are related to their
physiology, especially growth and
(15) respiration. By their growth many
species can deplete essential nutrients
within the system. Thus limiting their
own growth or that of other species.
Lund has demonstrated that in Lake
(20) Windermere the alga Asterionella is
unable to grow in conditions that it
itself has created. Once a year, in the
spring, this plant starts to grow
rapidly in the lake, using up so much
(25) silica from the water that by late
spring there is no longer enough to
maintain its own growth. The population
decreases dramatically as a result.
