Transcript
The study of organisms and their interaction with the environment Biotic factors---living parts to an ecosystem (plants, animals ect) Abiotic factors---nonliving parts to an ecosystem (temp, sunlight pH, soil) Organism---one individual living thing Population---group of individuals from the same species in the same living space (deer in Oneida Co.) Community---many populations that interact together Ecosystem--- the community plus the abiotic factors Niche---job or role of an organism in an ecosystem A lion, eats zebras, gets bitten by flies. After he kills for food the leftovers are for other animals and microorganisms Habitat---where an organism lives ex: rain forest, desert 1.) Competition--- when 2 or more individuals try to get the same resources (food, water, mate) it can be the same species or different species 2.) Predation—one organism kills another organism for food Prey---the one eaten Predator---the one that eats Symbiosis • What it means: • Two organisms that live together – Can be temporarily or for a longer time • At least one of the organisms benefits from the relationship • There are three types. Parasitism, Mutualism, Commensalism Parasitism (+/-) • A relationship between two organisms in which one organism benefits (parasite) and the other organism is harmed (host). ex.) Fleas, ticks, lice, tapeworms, ring worm, fungi Host Parasite Tapeworm/Human Commensalism (+/0) • A relationship between two organisms in which the host neither benefits nor is hurt by the relationship. Host No effect 1 benefits and the other doesn’t care ex: pilot fish and shark barnacle and whale Mutualism (+/+) • A relationship between two organisms in which both benefit • Cleaner fish and sea turtle Link with tons of symbiotic examples and pictures Nutrition 1.) Producers---an organism that makes its own food 2.) Consumer—an organism that gets their energy by eating others (4 types) Consumers 1.) Herbivore---only eats producers 2.) Carnivore---only eats consumers Omnivores---eats both plants and animals Decomposer---break down dead organisms—fungi/bacteria Food chain--- shows the sequence of energy transfer through an ecosystem Arrows show path of energy Food web---many food chains connected Trophic levels 1st, 2nd, 3rd each step of energy transfer in a ecosystem Energy Loss ---at each step of the trophic levels energy is lost. This loss of energy is released as heat and daily activities. Only 10 percent moves on to next level. Water Cycle water is not usually destroyed, it is moved from place to place. Carbon cycle plants take in carbon as carbon dioxide---animals eat the plants— then the animals release CO2 as a waste (what you breath out)---repeats Other factors affect this cycle---burning fossil fuels Nitrogen cycle Nitrogen is needed for building proteins. All organisms need it. Nitrogen is 78% of the atmosphere.---but only 1 type of organism can get the nitrogen from the air. Nitrogen fixing bacteria can take the nitrogen from the air and change it into a form the plants can use.—(mutualistic relationship) Succession change over time of the species in a community 2 types primary succession secondary succession Pioneer species---1st organisms to colonize an area (moss, lichens, grass) Climax community---final stable community—will be different for each biome Primary succession--- occurs in an area where no ecosystem has been new islands, glacier move, sidewalks Starts from bare rock—soil must be made 1st. Secondary succession—occurs where an ecosystem already existed—much faster---after a forest fire Terrestrial succession---- land Aquatic succession---water slow fill in of a body of water—can turn into a field
