parasitism and mutualism

Parasites live on a host they take what they need and don't benefit the animal they are living on

Fleas live in fur or beds of animals - feed by sucking blood

Head lice live on human scalps sucking the blood for food

Tapeworms attach to intestinal wall of hosts absorb nutrients

Mistletoe - lives on trees absorbs nutrients from host

Mustualism is when both organisms benefit

Oxpeckers- live on buffalo eat pests on buffalo and alert animal to predators

Cleaner fish eat dead skin of larger fish and in return get avoid getting eaten by the big fish
