A
biotic factors
Physical and chemical conditions that affect the ability of a given
species to live and reproduce in a particular place. Included in the
abiotic factors are temperature, light, water, oxygen, pH (acid-base
balance) of soil, type of substrate, and the availability of
minerals. Certain kinds of plants and animals will flourish in a
natural community if the conditions are present that permit their
survival. Species interact to influence the survival of one another.
One important principle of ecology is that no living organism
is independent of other organisms or of the physical environment, if
they share the same community.
