Ecological relationship between organisms | predation | parasitism | mutualism | competition
All of you are welcome in biology blossoms. In this lecture you will learn bio concepts. A niche includes the physical space in which they live, how they use the resources that are in that space, and how they interact with other organisms in that space.interaction among organisms within or between overlapping niches can be characterized into five types of relationships: competition, predation, commensalism, mutualism and parasitism. The last three subtypes are classically defined as relationships exhibiting symbiosis, but predation(predator and pray) and competition for food water, shelter, can also be considered as forms of symbiosis. Symbiosis refers to a close relationship in which one or both organisms obtain a benefit. In mutualism both species are benefited. But in commensilism one specie is benefited and other is neither harmed nor benefited.
