Symbiosis - Two species that live in close association together, Commensalism - Relationship between two species where one benefits and the other is neither harmed nor benefits, Mutualism - Relationship between two species where both benefit, Parasitism - Relationship between two species where one benefits (parasite) and the other is harmed (host), Brood Parasite - Type of parasite that lays its eggs in another species nest to avoid the cost of parental care, Exploitation - Any relationship where one species is harmed for the benefit of another, Epiphyte - A plant species that grows on top of another plant but doesn't harm it, Hemiparasite - A plant parasite that takes water or nutrients from its host but can still independently do photosynthesis, Obligate Parasite - A parasitic plant that fully depends on its host for sugar, water, and nutrients it cannot do photosynthesis, Ectoparasite - Animal parasite that lives briefly on the surface of its host, Endoparasite - Animal parasite that lives inside of its host, Predation - Exploitation relationship where one species kills and eats another, Arms Race - The evolution of escalating adaptations and counter-adaptations that occurs when two species are in an exploitation relationship, Aggressive Mimicry - When predators evolve a resemblance to harmless species so they can sneak up on prey, Mullerian Mimicry - When several truly dangerous species evolve similar looking signals to reinforce they are all dangerous, Batesian Mimicry - When a harmless species mimics the appearance of an actually harmful species, Aposematism - Bright warning colours that deter a predator from eating a poisonous prey species, Herbivory - Exploitation relationship where a plant species is harmed/eaten, Intraspecific Competition - Competition between two different species that have overlapping niches (use same habitat and similar resources), Niche Differentiation - When two species evolve behaviours that cause them to use different parts of a niche so competition is reduced, Competitive Exclusion - When two species occupy exactly the same niche one species will kill off the other species completely, Zonation - When different species occupy different horizontal bands in a habitat to reduce competition, Succession - When different species occupy the same habitat at different times to reduce competition, Stratification - When different species occupy different vertical bands in a habitat to reduce competition, Amensalism - Relationship between two species where one is killed and the other neither benefits nor is harmed, Allelopathy - When plants produce toxins in their leaves that fall and kill off any competitors growing around the tree,
