| Term | Definition |
|---|---|
| ecology | the scientific study of interactions among organisms and between organisms and their environment |
| biosphere | the combined portions of the planet in which all life exists |
| species | a group of organisms so similar to one another that they can breed and produce fertile offspring |
| population | groups of individuals that belong in the same species that are in the same area |
| community | assemblages of different populations that live together in a defined area |
| ecosystem | a collection of all the organisms that live in a particular place together with their nonliving environment |
| biome | a group of ecosystems that have the same climate and similar dominant communities |
| autotroph | organisms that capture energy from sunlight or chemicals and use that energy to produce food |
| producer | organisms that capture energy from sunlight or chemicals and use that energy to produce food |
| photosynthesis | the process where light, carbon dioxide, and water is converted into oxygen and glucose to produce energy |
| chemosynthesis | the process in which chemical energy is used to produce carbohydrates |
| heterotroph | organisms that rely on other organisms for their energy and food supply |
| consumer | organisms that rely on other organisms for their energy and food supply |
| herbivore | organisms that only obtain energy through eating plants |
| carnivore | organisms that only obtain energy through eating animals |
| omnivore | organisms that obtain energy through eating both plants and animals |
| detritivore | organisms that only obtain energy through eating the remains of plants, animals, and other dead matter |
| decomposer | organisms that only obtain energy through eating the remains of plants, animals, and other dead matter |
| food chain | a series of steps in which organisms transfer energy by eating and being eaten |
| food web | a link of multiple food chains within an ecosystem |
| trophic level | an individual step within a food chain or food web |
| ecological pyramid | a diagram that shows the relative amounts of energy or matter contained within each trophic level in a food chain or food web |
| biomass | the total amount of living tissue within a given trophic level |
| biogeochemical cycle | elements, chemical compounds, and other forms of matter that are passed from one organism to another |
| evaporation | the process by which water changes from liquid into atmsopheric gas |
| transpiration | the process by which water evaporates from leaves |
| nutrient | the chemical substances that an organism needs to sustain life |
| nitrogen fixation | the process that converts nitrogen gas into ammonia |
| denitrification | the process that converts nitrates into nitrogen gas |
| primary productivity | the rate at which organic matter is created by producers |
| limiting nutrient | a nutrient that is scarce within an ecosystem |
| algal bloom | when an aquatic ecosystem receives a large amount of a limiting nutrient and causes an immediate increase in algae and other producers |
