What two species are involved in Commensalism?
Commensalism is a type of relationship between two living organisms in which one organism benefits from the other without harming it. A commensal species benefits from another species by obtaining locomotion, shelter, food, or support from the host species, which (for the most part) neither benefits nor is harmed.
Which is an example of Commensalism apes?

What is primary succession apes?
Primary succession occurs when there is only rock in the area. Since soil is needed in order for plants to grow, the rock must be broken down gradually over time. This is a job for moss and lichens (pioneer species). These organisms are the first forms of (multicellular) life that will inhabit this new area.
What is a keystone species apes?
Keystone Species. species, such as the sea otter, that has a large effect on its community or ecosystem so that its removal or addition to the community leads to major changes in the abundances of many or all other species.
What do all keystone species have in common?
Any organism, from plants to fungi, may be a keystone species; they are not always the largest or most abundant species in an ecosystem. However, almost all examples of keystone species are animals that have a huge influence on food webs. The way these animals influence food webs varies from habitat to habitat.
What are the features of a keystone species?
One of the defining characteristics of a keystone species is that it fills a critical ecological role that no other species can. Without its keystone species, an entire ecosystem would radically change—or cease to exist altogether.
Do keystone species have low abundance?
Keystone species have a relatively low abundance compared to their influence on the ecosystem.
Why should we protect keystone species?
Keystone species help create the conditions for other wildlife and plants to thrive. Wolves, for instance, help keep elk from stripping riverbanks bare, which benefits trout and beavers and provides habitat for songbirds.
How do humans affect keystone species?
Our pollution and emission of greenhouse gases are causing the ocean temperature to rise, and some species, including these two keystone species, are unable to adapt to the changing environment. People need to sustain the habitats of keystone species in order to minimize any more drastic environmental changes.
Is a lion a keystone species?

This feeding behavior keeps the savanna a grassland and not a forest or woodland. With elephants to control the tree population, grasses thrive and sustain grazing animals such as antelopes, wildebeests, and zebras. Elephants are the keystone species that maintain the entire savanna ecosystem.
Why is a starfish a keystone species?
Sea stars are important members of the marine environment and are considered a keystone species. A keystone species preys on animals that have no other natural predators and if they are removed from the environment, their prey will increase in number and may drive out other species.
