Biotic environmental factors

from Wikipedia, the free encyclopedia

As biotic are environmental factors summarized at which living things can be seen involved. They result from the interactions between individual species within an ecosystem . In contrast, there are abiotic factors , which represent inanimate interaction partners.

Interrelationships of two types (bi-systems)

When different species live together in the same area, at least one of the species is usually affected. This influence can be an advantage or a disadvantage. Interactions with a negative effect on at least one of the partners are summarized as antibiosis .

In the following scheme, the type of interaction is marked with a symbol. The plus sign (+) stands for positive, the minus sign (-) for negative, the number zero (0) for no influence at all.
