However, it is argued that there are very few truly service-service mutualisms as there is usually a resource component to the symbiosis. In the case of the anemone-anemone fish mutualism, the nutrients symbiosis definition the anemone fish waste provide food for the symbiotic algae, which live within the tentacles of symbiosis definition anemone and provide energy to the anemone through photosynthesis.
Symbiosis definition this way, symbioses are shown to be highly complex and indicative of the delicate balance within ecosystems. Commensalism Commensalism is a symbiosis in which one organism benefits from, and is often completely dependent symbiosis definition, the other for food, shelter, or locomotion, with no obvious effect on the host.
The relationship between whales and barnacles is an example of commensalism.
The barnacles attach themselves to the tough skin of whales, and benefit from widespread movement and exposure to currents, from which they feed, while the whale is seemingly unaffected by their presence.
Amensalism On the opposing side of commensalism is amensalism. This occurs symbiosis definition one organism is inhibited or damaged by the presence symbiosis definition the other, who does not benefit.
Amensalism may involve competition, in which a larger, more powerful, or environmentally better adapted organism excludes another organism from its food source or shelter; for example, one plant shades out another symbiosis definition growing at its normal speed and height.
The relationship between cattle egrets and cattle. The cattle egret will eat insects that have been disturbed when the symbiosis definition forage.
In some of these commensalism relationships, the symbiosis definition that is reaping the benefit will use the other for protection or transportation. A hermit crab taking up residence in an empty seashell. A spider building a symbiosis definition on a tree.
Examples of Symbiosis
Parasitism In parasitism, one organism benefits from the relationship but at the expense of the other. Antagonism occurs when one organism is damaged or killed by another through symbiosis definition chemical secretion.

An example of competition is a sapling growing symbiosis definition the shadow of a symbiosis definition tree. The mature tree can rob the sapling of necessary sunlight and, if the mature tree is very large, it can take up rainwater and deplete soil nutrients.
Throughout the process, the mature tree is unaffected by the sapling. Indeed, if the sapling dies, the mature tree gains nutrients from the decaying sapling.
