1. Commensalism, Mutualism & Parasitism
Habitats and interactions 1pt By Max Malouf

2. Commensalism
Commensalism is the interaction between 2 organisms were 1 organism benefits and the other does not.
For example: ‘Cattle egrets’ – These are birds that live near cattle because when the cattle ‘graze’, their movements stir up insects. These birds feed of the insects benefiting the bird and not harming the cow.
Example 2: These live in anemones which protects them from predators. Predators are poisoned by the nematocysts of the anemones.

3. Mutualism
Mutualism in an interaction between 2 organisms were both organisms benefit.
For example: Digestive bacteria and humans – humans have what are often called ‘good’ bacteria this bacteria lives in the digestive system. The bacteria lives in order to help the human digest food.
Tasty
Example 2: The sea anemones are saved by the clownfish from being eaten by their predators, the butterfly fish. These live in anemones which protects them from predators. Predators are poisoned by the nematocysts of the anemones.

4. Parasitism
Parasitism is an interaction between 2 organisms where 1 benefits in and the other is harmed.
For example: A mosquito biting a human. The mosquito benefits because is feeds on the blood.
Example 2: leeches are very similar to mosquitos they puncher your skin and such on your blood and feed on it
