commenalism
That is known as a symbiotic relationship, where two species rely on each other for survival. This can be mutualistic, where both species benefit, or parasitic, where one benefits at the expense of the other.
the condition in which one or both species in a mutualistic association are completely dependent on the presence of the other species.
It is called obligate (dependent) symbiosis when a species cannot independently exist without another.
A species becoming dependent on another species .
A large number of species are usually dependent on the Keystone species. The Keystone species usually regulates the abundance of the other species.
When both species benefit from the relationship, it is known as mutualism. In mutualistic relationships, both species provide resources or services that are advantageous to the other, leading to a symbiotic interaction where both parties gain from the association. This kind of relationship is common in nature and can enhance the survival and reproductive success of both species involved.
An indirect relationship is a relationship in which neither of the factors are dependent on each other.
Mutualism is a type of symbiotic relationship between two species where both organisms benefit from the association. Each species provides a service or resource that the other species needs, creating a mutually beneficial interaction. This relationship is a common strategy in nature for organisms to increase their chances of survival and reproduction.
This is a "keystone" species.
A close relationship between two species in which both benefit is called mutualism. In mutualism, both species have evolved to depend on each other for survival or reproduction, and both receive some form of reward or benefit from the relationship. This type of interaction is common in nature and can be observed in various ecological settings.
A dependent relationship in an ecosystem may be in various forms. This may be parasitic where only a parasite is dependent on the host or symbiotic where both organisms depend on each other.
five ways that humans are dependent on other species because humans need them for shelter, food, fresh air, medicine and clothes.
