Biotic – The biotic part of the environment is all of the organisms that live together and interact with one another. Abiotic - The abiotic part of the environment includes all of the physical factors – water, soil, light and temperature – that affect organisms living in a particular area. Population – A population is a group of individuals of the same species that live together in the same area at the same time. Community – A community consists of all of the populations of different species that live and interact in an area. Ecosystem – An ecosystem is made up of a community of organisms and its abiotic environemnt. Biosphere – The biosphere is part of Earth where life exists. Chapter One – Section Two Living Things Need Energy Producers – An organism that uses sunlight directly to make food is called a producer. Consumers – Organisms that eat producers or other organisms for energy are called producers. Herbivore – A herbivore is a consumer that eats plants. Carnivore – A carnivore is a consumer that eats animals. Omnivore – An omnivore eats a variety of organisms, both plants and animals. Scavenger – Scavengers are animals that feed on the bodies of dead animals. Food Chain - A food chain represents how the energy in food molecules flows from one organism to the next. Food Web – A food web shows the many energy pathways possible in an ecosystem. Energy Pyramid – A diagram shaped like a triangle that shows the loss of energy at each level of the food chain. Habitat – The environment where an organism lives is its habitat. Niche – An organisms way of life and its relationships with its abiotic and biotic environments. Chapter One – Section Three Types of Interactions Limiting Factors – When a resource becomes scarce, it limits the growth of a population. Carrying Capacity – The largest population that a given environment can support over a long period of time is known as the carrying capacity. Competition – When two or more populations try to use the same limited resource, it is called competition. Prey – The organism that is eaten by others is known as prey. Predator – The organism that eats prey is known as a predator. Symbiosis – A close, long-term association between two or more species. Mutualism – A symbiotic relationship in which both organisms benefit. Commensalism – A symbiotic relationship in which one organism benefits while the other is unaffected. Parasitism – A symbiotic association in which one organism benefits while the other is harmed Coevolution – The long term changes that take place in two species because of their close interactions with one another
