Three important needs in an organism’s habitat What are food, water, and shelter? Nonliving parts of an ecosystem What are abiotic factors? The place where an organism lives and provides the things an organism needs What is a habitat? The smallest unit of ecological organization What is an organism? The study of how organisms interact with each other and with their environment What is ecology? Two needs of a plant for survival What are water, sunshine, and space? How water and sunshine help a plant stay alive What is so the plant can make its own food? A group of organisms that are physically similar and can reproduce with one another to produce fertile offspring What is a species? The role of earthworms in an ecosystem What is adding nutrients by decomposing matter? An example of a population What are gray wolves? Definition of population density What is the number of individuals of a population in a specific area? Counting the number of organisms in a small area and multiplying to estimate the number in a larger area What is sampling? The major way new individuals are added to a population What is the birth of offspring? An environmental factor that prevents a population from increasing What is a limiting factor? The largest population that a population can support What is carrying capacity? An early winter frost preventing further growth in a tomato garden What is a limiting factor? If deer hunting were banned in Michigan, the population of deer would probably … What is increase at first and then level off? Leaving a population What is emigration? Two possible reasons for a population to decrease What are over-hunting, disease, lack of food, extreme weather conditions, and emigration? An organism’s particular role, or how it makes its living What is a niche? Behaviors and physical characteristics of species that allow them to survive in their environment What are adaptations? By hunting at different times of day, the hawk and owl are able to reduce … What is competition? An interaction in which one organism kills and eats another What is predation? An example of a predator adaptation What is a shark’s powerful jaws? A jellyfish paralyzes a tiny fish with its poisonous tentacles, the fish is the … What is the prey? A close relationship between two species that benefits at least one of the species What is symbiosis? A flea living on a dog, the dog is the … What is the host? Mutualism, commensalism, and parasitism are types of … What are symbiotic relationships? Escherichia coli that live in your intestine and help break down food are an example of … What is mutualism? Description of two common relationships among organisms and an example of each. Two common relationships among organisms are: 1. Mutualism-a relationship in which both species benefit from each other. Ex. E coli /humans 2. Commensalism-a relationship in which one species benefits and the other is neither helped or harmed. Ex. Robin/maple tree 3. Parasitism-a relationship in which one species benefits and the other is harmed. Ex. Dog/flea 4. Predation-a relationship in which one organism kills and eats the other. Ex. Lion/zebra
