Question

what are the different types of symbiosis with examples
please help me I will mark you as brainest​

Answer 1

Answer:

There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism.

Mutualism: both partners benefit. ...

Commensalism: only one species benefits while the other is neither helped nor harmed. ...

Parasitism: One organism (the parasite) gains, while the other (the host) suffers.

Answer 2

Answer:

Because different species often inhabit the same spaces and share—or compete for—the same resources, they interact in a variety of ways, known collectively as symbiosis. There are five main symbiotic relationships: mutualism, commensalism, predation, parasitism, and competition.

Parasitism

In parasitism, one organism benefits from the relationship but at the expense of the other. The organism may live inside the other's body or on its surface. In some of these parasitic relationships the host dies and in others, it is important that the host remain alive.

• Example: Fleas and mosquitoes feed on blood from other organisms.

In this type of parasitic relationship, the host needs to stay alive and it is not damaged greatly.

• Example: Barnacles that attach to the bodies of whales.

The whale is not harmed greatly, but may have some pain or itching.

Mutualism

Mutualism is a close relationship where both parties benefit. Both species will benefit from the relationship and many of these relationships are ling-lasting.

• Example: Cleaning symbiosis

In the ocean, certain species, like shrimps and gobies, will clean fish. They remove parasites, dead tissue, and mucous.

• Example: Dogs and humans have enjoyed a mutualistic symbiosis for centuries.

The dogs supply protection and companionship and the humans provide food and shelter.

Endosymbiosis and Ectosymbiosis

Endosymbiosis is one species living inside another one.

• Example: Protozoans that live inside termites and help them digest wood.

Ectosymbiosis is one species living on the surface of the other species.  

• Example: Lice that feed on the skin, blood, or oil secretions of the host.

Commensalism in Nature

Everything in nature is interconnected in one way or another. And many of these relationships are commensalistic in nature.

• Barnacles

While some barnacles are parasitic and others root on nonliving surfaces like rocks, many species are commensal. In fact, many species of barnacles are evolved specifically to be commensal with particular species of animals, such as sea turtles.

• Birds

Birds that live in the hollows of trees are commensal. Their presence generally does no harm to the tree, but the tree provides the bird with shelter and protection.
