What 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, & Parasitism• Mutualism: 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, & Niche• Habitat: Habitat is the
natural environment of a species
• Community: Communities are networks of interacting species
• Niche: A niche is role a species plays in an ecosystem to affect another species
• Habitat examples: the rainforest is the habitat of a poison dart frog
• Community examples: Roadrunners, rattlesnakes, and mice all interact together in the same habitat
• Niche examples: A mountain lion kills a deer and leaves leftovers, and a vulture comes and feeds on the carcass
Predator & Prey• Predator:
carnivorous species that hunts, kills, and eats other species to survive
• Example: A piranha is a predator that hunts angelfish
• Prey: An omnivorous or herbivorous species that is hunted, killed, and eaten by predators.
• Example: An angelfish is prey to the piranha

Pioneer Species & Competition• Pioneer Species: A species that reestablishes itself
in a different habitat• Example: 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 resources
• Examples: Sharks compete with each other for food, and when there is no food available, they eat each other.
Carrying Capacity & Species Population• Carrying Capacity: How
many animals a habitat can sustain
• Example: The reason deer are hunted is because if there are too many, they’ll use up all the resources.
• Species Population: all individuals of a specific species
• Example: Shark species populations are declining over time
Limiting Factors & Succession• Limiting Factors: Causes for a species population
to stop growth or decrease in size• Examples: Predators can be limiting factors if they
kill too much of their prey• Succession: changes a species goes through over
time• Examples: A tree starts out as a seed, then goes
through succession and turns into a tree
