Ecology EmergesPaige Daniel, Maggie Laskey, Mary Lulloff, Bryce SutterWhat is ecology?Ecology is the scientific study of interactions of organisms with one another and with the physical and chemical environment.

SymbiosisSymbiosis is when two different living things are in close association and interact with one another, and it often times benefits both species.An example of this would be bees and orchids, because the bees get pollen from the orchids and this can help the orchids reproduce.

Mutualism, Commensalism, & ParasitismMutualism: mutualism is when two organisms work together to benefit each other.Commensalism: commensalism is when two living things interact and only one benefits and the other is neither harmed nor helped.Parasitism: parasitism is when two organisms interact and one is harmed and the other is helped.

Mutualism: Red-billed Oxpeckers feed on parasites found on Impalas. Oxpeckers get food and Impalas get cleaned.Commensalism: golden jackals will trail tigers and feed on what it kills. Jackals gain food and tiger gains nothing.Parasitism: Leeches attach themselves to humans for food. Humans are lose blood.

Habitat, Community, & NicheHabitat: Habitat is the natural environment of a speciesCommunity: Communities are networks of interacting speciesNiche: A niche is role a species plays in an ecosystem to affect another speciesHabitat examples: the rainforest is the habitat of a poison dart frogCommunity examples: Roadrunners, rattlesnakes, and mice all interact together in the same habitatNiche examples: A mountain lion kills a deer and leaves leftovers, and a vulture comes and feeds on the carcass

Predator & PreyPredator: carnivorous species that hunts, kills, and eats other species to surviveExample: A piranha is a predator that hunts angelfishPrey: An omnivorous or herbivorous species that is hunted, killed, and eaten by predators.Example: An angelfish is prey to the piranha Pioneer Species & CompetitionPioneer Species: A species that reestablishes itself in a different habitatExample: The Coatimundi, originally found only in the Southern parts of Arizona, have now been spotted in Northern Arizona.Competition: When several species compete for similar resourcesExamples: Sharks compete with each other for food, and when there is no food available, they eat each other.

Carrying Capacity & Species PopulationCarrying Capacity: How many animals a habitat can sustainExample: The reason deer are hunted is because if there are too many, theyll use up all the resources.Species Population: all individuals of a specific speciesExample: Shark species populations are declining over time

Limiting Factors & SuccessionLimiting Factors: Causes for a species population to stop growth or decrease in sizeExamples: Predators can be limiting factors if they kill too much of their preySuccession: changes a species goes through over timeExamples: A tree starts out as a seed, then goes through succession and turns into a tree
