Ecology

Ecology= the study of interactions among organisms and their milieu. Biosphere= the portion of earth that supports life. Abiotic factors= non- keep move of the environment Biotic factors= living parts of the environment Levels of Organization in Ecology: 1. organism ( hotshot thing) 2. population (many things of the identical species) 3. communities (a mix of disparate species) 4. ecosystem (living things and the environment) 5. biosphere (contains all ecosystems) habitat= place where an organism lives niche= the map and position a species has in its environment symbiosis= living to totalher; a relationship between two organisms 1. commensalism= one organism benefits, the otherwise(a) is neither benefitted or harmed. 2. mutualism= both organisms benefit 3. parasitism= one organism benefits, the other is harmed *energy flow= 10% is passed on, 90% is wasted autotrophs= producers; make provender; plants heterotrophs= consumers; cannot make their own play outable Three types of heterotrophs 1. herbivores= only eat autotrophs (plants) 2. carnivores= eat other heterotrophs (meat) 3. omnivores= eat both autotrophs and heterotrophs scavengers= eat dead stuff; vultures, buzzards *decomposer= rift waste the complex compounds of dead and decaying plants and animals into things that can be absent and utilize by organisms. food chain sun->grass->grasshopper->snake->eagle **arrow shows command of ENERGY work** algae->fish->heron->alligator trophic level= each step in a food chain --References --> this is uninterrupted out of a text book or from a spill the beans handout, it is useful, if someone is looking for a polish on ecological terms, and the mission statement of this site is to bid lecture notes et al. for others to use, for that reason I give this a sizea! ble thumbs up. Ok people, please read the title which clearly says STUDY notES. This is not directly from a text book, these are real notes from my biological science class, copied off of an overhead projector, written by my biology teacher. Thanks. You could fork out improved this by placing it into some mental of acceptable undertake format. You also could have used staring(a) sentences.
