Ecology Flashcards
An animal that is hunted or killed:
Prey
An animal that is the hunter:
Predator
Two species that live in close contact with one another
Symbiotic Relationship
Relationship where both organisms benefit:
Mutualism
Relationship where one organism benefits and the other is harmed:
Parasitism
Relationship where one organism benefits and the other is unaffected:
Commensalism
A species that thrives in an ecosystem
Native Species
A species that causes ecological harm:
Invasive Species
Two or more organisms depend on the same resource:
Competition
What is the difference between a parasite and a host?
A parasite takes the nourishment / causes harm to the host. The host is the one that is infected.
The small fish will typically hide inside of the jellyfish’s stinging tentacles if the stinging does not affect them. The tentacles provide protection for the fish from larger predators.
Commensalism
A louse attaches itself to the tongue of a fish. It severs the tongues and attaches itself to the stub. Afterwards, it eats the fish mucus.
Parasitism
There are many types of bacteria found in yogurt. Once we eat the yogurt, the bacteria get fed and in return help us digest our food.
Mutualism
In the marine ecosystem, a great white shark will hunt earless seals as a meal. When the earless seal population is low, they will hunt stingrays.
