How organisms interact in a community

Commensalism

1 organism benefits, while the other organism is neither helped or harmed

Example of Commensalism

A Remora (fish) swims with a shark and feeding from the scraps of the shark

Example of Mutualism

Aphids (ants) suck fluids from a plant, "honeydew" sugar water leaks out of their butt, larger ants lick the honeydew, so they protect the aphids in order to get the honeydew

A clown fish is protected by an anemone's stinging tentacles. The Sean anemone gets nothing out of the relationship

Commensalism

Ants get honeydew from and Aphids anus, the Ants protect the Aphids

Mutualism

Example of parasitism

Tick sucking blood out of an animal

Predation

act of one organism killing another for food

Coevolution

back and forth evolutionary adjustments between interacting members of a community

Niche

functional role of an organism in an ecosystem (job)

Parasitism

one organism lives in or feeds off another organism

Secondary Compounds

plants defenses against predators, such as the oil "Urushiol" in poison ivy that causes itching

Mustard, Cabbage, Radish

puts out a strong aroma and taste as a secondary compound for protection

Dolphin

the only mammal on earth that will murder, not just kill for food

Urushiol

the type of oil made from poison ivy that results in skin irritation

Symbiotic relationship

when 2 or more species live together in a close long term relationship

Mutualism

when both organisms benefit from the relationship-
