Symbiosis

• A relationship between 2 different species that live in, on or near each other.

Kinds of Symbiosis

• Commensalism• Mutualism• parasitism

commensalism

• A symbiotic relationship in which both organisms are benefited.

Examples of commensalism

• Frogs and the vermilaid (rain forest plant)- frog uses the plant to hid from the sun and rain which means the frog is benefitted and the vermilaid isn’t affected.

Mutualism

• A symbiotic relationship in which both organisms are benefitted

Examples of mutualism

• Egyptian plover and crocodile- the Egyptian plover gets benefitted by going in the opened crocodiles mouth and picks out the extra meat that is stuck in its teeth while the crocodile just lays there. The crocodile also gets benefitted by a free dental treatment.

Parasitism

• A symbiotic relationship in which the parasite benefits and the host is harmed

Examples of parasitism

• Human and the tick- the tick benefits because it finds a place on the human and starts to suck the blood out of them. The human is affected because they are losing blood and could get sick.

Non symbiotic relationships

• Other relationships that are not symbiotic: competition, cooperation, and predation

competition

• Competing another organism for food, water, space, nesting areas, and mates

Examples of competition

• A buck against a buck- they compete for mates in the woods. They do this by fighting and hitting each others horns together.

cooperation

• When two organisms work together

Examples of cooperation

• Horses- they cooperate with each other by helping one another take down another organism.

predation

• When one organism hunts, kills and eats the other organism

Examples of predation

• Barn owl and mice- the barn owls are the predators which hunt the mice and eat them.
