Introduction to Ecology and the Biosphere
193002820 | ecology | the scientific study of the interactions between organisms and their environment | |
193002821 | abiotic factors | Non-living chemical and physical factors such as temperature, light, water, and nutrients | |
193002822 | biotic factors | the living components | |
193002823 | ecological time | minutes, months, years | |
193002824 | evolutionary time | decades, centuries, millenia, and longer | |
193002825 | organismal ecology | the behavioral, physiological, and morphological ways individuals interact with the environment | |
193002826 | population | a group of individuals of the same species living in a particular geographic area | |
193002827 | population ecology | the study of factors that affect population size and composition | |
193002828 | community | consists of all organisms of all the species that inhabit a particular area | |
193002829 | community ecology | examines the interactions between populations, and how factors such as predation, competition, and disease affect community structure and organization | |
193002830 | ecosystem | consists of all the abiotic factors in addition to the entire community of species that exist in a certain area | |
193002831 | ecosystem ecology | the energy flow and cycling of chemicals among the various abiotic and biotic components | |
193002832 | landscape ecology | the array of ecosystems and their arrangement in a geographic region | |
193002833 | landscape/seascape | consists of several different ecosystems linked by exchanges of energy, materials, and organisms. |
