Biological interaction - Wikipedia
of symbiosis. Symbiosis refers to a close relationship in which one or both organisms obtain a benefit. Examples of predation are owls that eat mice, and lions that eat gazelles. Competition is His specialty is tumor biology. He also has a. Or, you may have begun a romantic relationship that started out promising, but the label assigned to the primary caregiver (usually the biological mother) is. is planktonic growth of bacteria and archaea in frigid marine waters (~ cells /ml) (psychrophiles) Lichen = symbiotic relationship between algae and fungi.
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. That's what commensalism is all about. One plant gets a place to live and the other doesn't care and is not hurt. 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.
Symbiotic Relationship: Definition & Examples
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. Imagine if we are different species, but have the same skills.
These trees get so big, that roads in Sequoia National Park run right through some of them, which span over 20 feet in diameter. Birds make the canopy of these trees home, and many land-dwelling animals live in the forest below.
Welwitschia Mirabilis Not all plants like the rain, though. Growing in the Namib desert, the Welwitschia Mirabilis lives in some of the driest conditions on Earth. Strangely, it's a plant that only has one or two large leaves that wrap around itself, appearing to be wilted and dry.
However, don't be fooled by its less-than-attractive appearance, this plant can live over 1, years. It's deep root system allows it to tap into groundwater stores in even the driest conditions. Nepenthes So far, we've looked at two types of flora that are photosynthetic, meaning they make their own food from sunlight.

However, some plants take a more active approach to getting food. Nepenthes is a family of pitcher plants native to the jungles of Borneo. These plants have adapted leaves that form a large pitcher structure.
The pitcher is filled with sweet smelling liquid designed to trap insects and even small frogs in some species. The animals drop into the pitcher, but soon find that the smooth sides make it impossible to climb back out.
