Symbiosis describes close interactions between two or more different species. It is different from regular interactions between species, because in a symbiotic relationship, the two species in the relationship live together. Many organisms are involved in symbiotic relationships because this interaction provides benefits to both species.
However, there are types of symbiosis that are not beneficial and may in fact harm one or both of the species. Symbiotic relationships can be obligate or facultative.
Obligate symbiosis is when two organisms are in a symbiotic relationship because they can't survive without each other. Facultative symbiosis is when the species live together by choice.
There are four main types of symbiotic relationships: Mutualism Mutualism occurs when both species benefit from the interaction. Because mutualism is beneficial to both species involved, there are a wide variety of mutualistic interactions, and these are most common in nature. For example, there may be a nutritional benefit to be gained from the symbiosis, such as with lichen.
Lichen is made up of both algae and fungi, and together they provide each other with food and structure. This type of symbiosis is both obligate and mutualistic.
Competition This relationship is when two species are competing for the same resources. If there are only ten trees with fruit and I am better at reaching the fruit than you are, sorry, you don't get any. When you don't get any fruit you die. That's just the way nature works. It could go the other way though. If I kill all of the trees with the high fruit and only low fruit is left, you win.
Competition usually happens when you have a limited amount of resources. There is one important idea to remember. Sometimes no one wins. Sometimes if everything is even it can be a stalemate and both species compete, but both survive.What Is The Definition Of Symbiosis In Biology?
Imagine if we are different species, but have the same skills. No one would be a winner in that case. Mutualism The heart of mutualism is that two species live together in harmony. Both species receive an advantage by working with the other.
More importantly, it helps them both survive. We previously spoke about the relationships between bugs and plants. That often happens as a mutualism type of relationship.

We suppose you could also use rescue dogs as an example. The masters take care of the dogs and the dogs learn how to save people. Everyone benefits in the end.
