3.3 Species interactions by Emily Kauffman

Competition

when 2 or more species is competing for food.the food will more likely get away cause the predators end up fighting for it then it runs. or they will kill it them fight over it

Example: lion and cheetah going for a gazelle

Predation

When one predator hunts a prey. they capture the prey, then they kill it, then they eat it or play with it.

Example: fox eats/hunts rabbits

Parasitism

When a parasite(tick, lice, fleas, leeches,etc.) benefits off of a host(humans, animals) host is being harmed/affected and parasite is being affected in a positive way.

Example: tick in woods falls onto a human, then tick bites human and sucks it blood till human takes tick off.

Ectoparasites are parasites that live outside the body. In animals, they live on the skin and can cause itching and rashes.

Endoparasites

endoparasites are parasites that live inside the body.

Example ringworms, tapeworms, hookworms, and whipworms

mutualism

Involves the exchange of goods or services between two species. When bees/butterflies get nectar/pollen from a flower they both are affected positively because then the pollen gets moved to another flower and that's how some flowers reproduce. and the bees get the nectar and take it to their hive to make honey

Commensalism

Where one species is benefiting off of another without harm being done. like when medium/small fish stay by a shark for protection.

The host is being harmed because they can get diseases from parasites like ticks.

there are several diseases like lyme disease, alfagal disease, rocky mountain spotted fever disease, etc.

Ticks have a menacing mouth covered in hooks that they use to get under the surface of our skin and attach themselves for several days while they fatten up on our blood.

The bottom of the hypostome is also covered in rows of hooks that give it the look of a chainsaw. Those hooks act like mini-harpoons, anchoring the tick

They're not like a mosquito that can just put their mouth parts in and out nicely, like a hypodermic needle.

Instead, a tick digs in using two sets of hooks. Each set looks like a hand with three hooked fingers. The hooks dig in and wriggle into the skin. Then the tick pushes its head/mouth into the host and sucks the blood for several days.
