Competition: occurs when one or more resources are limiting (food, land, light, soil …).Symbiotic relationships can be beneficial to a species, both, or harmful to one of the two. T his interaction it is called symbiosis. They are those that occur between individuals of different species. For survival, it is imperative that relations between them are established, sometimes beneficial and sometimes harmful.
The biocenosis is formed in turn by different populations, which would be the set of individuals of the same species occupying an area. The group of all living beings in an ecosystem is called biocenosisor community. What types of relationships in addition to those you know? Do you feel like to know them? INTRODUCTION Predation, parasitism, competition… all living beings, besides interacting with the environment, we relate to other living beings.
