What are two examples of commensualism, mutualism, and paratism?

Answer 1

commensalism 1) Some species of barnacles are found only as commensals on the jaws of whales
2) Anemonefish
3) Barnacles adhering to the skin of a whale or shell of a mollusk

mutualism 1)Paramecium bursaria & unicellular green algae
2)sponges

Parasitism
viruses, bacteria, fungi, protozoans, flatworms (tapeworms and flukes), nematodes, insects (fleas, lice), and arachnids (mites).

Answer 2

mutualism is an interaction between two or more species where both species derive benefit.
Examples of mutualism are the relationship between animals such as bees and butterflies and flowers and ants and a shrub brush called bull's horn acacia. The ants nests inside the plants thorns recieves food while protecting the plant from other herivores. They also trim back vegetation that shades the shrub.

A famous land version of symbiosis is the relationship of the Egyptian Plover bird and the crocodile. In this relationship, the bird is well known for preying on parasites that feed on crocodiles which are potentially harmful for the animal. To that end, the crocodile openly invites the bird to hunt on his body, even going so far as to open the jaws to allow the bird enter the mouth safely to hunt. For the bird's part, this relationship not only is a ready source of food, but a safe one considering that few predator species would dare strike at the bird at such proximity to its host


2.Commensalism refers to an interaction between two living organisms, where one organism benefits and the other is neither harmed nor helped.Other forms of commensalism include:

Phoresy: One animal attaching to another animal for transportation only. This concerns mainly arthropods, examples of which are mites on insects (such as beetles, flies, or bees), and pseudoscorpions or millipedes on birds. Phoresy can be either obligate or facultative (induced by environmental conditions).

Inquilinism: Using a second organism for housing. Examples are epiphytic plants (such as many orchids) which grow on trees, or birds that live in holes in trees.

Metabiosis: A more indirect dependency, in which the second organism uses something the first created, however after the death of the first. An example is the hermit crabs who use gastropod shells

3.Parasitism, in which one member of the association benefits while the other is harmed
Parasites that live inside the body of the host are called endoparasites (e.g., hookworms that live in the host's gut) and those that live on the outside are called ectoparasites (e.g., some mites). An epiparasite is a parasite that feeds on another parasite. This relationship is also sometimes referred to as "hyperparasitoidism", especially in the insect world
