Ecology: Study of interactions of living organisms with one another and with their physical environment
Habitat: place where a particular population of a species lives
Community: the many different species that live together in a habitat
Ecosystem: a community and all of the physical aspects of its habitat (soil, air, water, weather
Abiotic: the physical aspects of a habitat
Biotic: the living organisms of a habitat
Biodiversity: number of species living within an ecosystem
Pioneer Species: the first organisms to live in a new habitat; usually small, fast growing plants
Succession: regular progression of species replacement
Primary Succession: succession that occurs where plants have not grown before (ex: volcanoes, receding glaciers)
Secondary Succession: succession that occurs in areas where there has been previous growth (ex: forest fires, forest clearings)
Primary Productivity: the rate at which organic material is produced by photosynthetic organisms in an ecosystem
Autotroph: Organisms that make their own food, producers
Heterotroph: Organisms that consume producers for food, consumers
Producer: organisms that first capture energy and that make their own food (plants)
Consumer: organisms that consume producers for food (animals)
Trophic Level: a specific level in an ecosystem based on the organism’s source of energy
Food Chain: the path of energy through the trophic levels of an ecosystem
Herbivores: second trophic level, animals that eat plants or other primary producer
Carnivores: third trophic level, animals that eat herbivores
Omnivores: both herbivores and carnivores
Detritivores: obtain energy from organic waste and dead bodies, release nutrients back into environment (decomposers: worms, bacteria, fungi)
Food Web: a complicated, interconnected group of food chains
Biomass: the dry weight of tissue and other organic matter found in a specific ecosystem
Predation: the act of one organism feeding on another
Symbiosis: two or more species live together in a close, long-term association
Parasitism: one organism feeds on and usually lives on or in another, does not usually kill the host (ticks)
Mutualism: a symbiotic relationship in which both species benefit (ants and aphids)
Commensalism: one species benefits and the other is neither harmed nor helped
Fundamental Niche: the entire range of conditions an organism is potentially able to occupy
Realized Niche: the part of its fundamental niche that a species occupies
Biome: major biological community that occurs over a large area of land
Introduced Species: an organism that is not native to an area, but is brought there intentionally or unintentionally by humans
Niche: how and where an organism lives and the job it performs. This includes diet, activity, how it affects energy flow in systems. THIS IS NOT THE SAME AS HABITAT
