E
cology
is the study of environmental_____________,
or as it is sometimes called, the economy of nature. "Environmental"
usually means relating to the natural, versus human-made world; the
"systems" means that ecology is, by its very nature, not
interested in just the _____________
of
nature individually but especially in how the parts interact. Ecology
is technically an _____________
discipline,
such as mathematics or physics, although in public or media use, it
is often used to connote something that is “ecologically bad” or
is or is not “good for the ecology”. More properly ecology is
used only in the sense that it is an academic discipline, no more
evaluative than mathematics or physics. Most professional ecologists
are not terribly unhappy when ecology is used in the normative sense,
preferring the wider public awareness of environmental issues today
compared to the widespread _____________
of
three decades ago.
T
he
subject matter of ecology is normally divided onto four broad
categories:_____________,
having to do with the response of single species to environmental
conditions such as temperature or light; _____________,
usually focusing on the abundance and distribution of individual
species and the factors that cause such distribution; ____________,
having
to do with the number of species found at given location and their
interactions; and, having to do with the structure and function of
the entire suite of microbes, plants, and animals, and their abiotic
environment, and how the parts interact to generate the whole. This
branch of ecology often focuses on the energy and nutrient flows of
ecosystems, and when this approach is combined with computer analysis
and simulation we often call it systems ecology. _____________,
which may operate at any of these levels but most commonly at the
physiological or population level, is a rich and dynamic area of
ecology focusing on attempting to understand how natural selection
developed the structure and function of the organisms and ecosystems
at any of these levels.
