| biotic | related to living things |
| abiotic | related to non-living things |
| organism | any living thing |
| population | group of the same type of organisms living in a specific area. |
| community | group of different populations of various organisms living together in the same area. |
| ecosystem | community of living organisms and their environment, interacting as a system. |
| biosphere | part of Earth where life exists, including land, water, and the atmosphere. |
| photosynthesis | process by which plants use sunlight to turn carbon dioxide and water into food (glucose) and oxygen. |
| producer | an organism, like a plant, that makes its own food using sunlight or other energy sources. |
| cellular respiration | process by which cells convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts. |
| consumer | organism that eats other living things for energy, such as animals or humans. |
| herbivore | animal that primarily eats plants. |
| carnivore | animal that primarily eats other animals. |
| omnivore | animal that eats both plants and animals. |
| trophic levels | different levels in a food chain, indicating how energy and nutrients flow through an ecosystem, from producers to various levels of consumers. |
| food chain | sequence that shows how energy and nutrients move from one organism to another, starting with a producer and ending with a top consumer. |
| food web | network of interconnected food chains that shows how different organisms in an ecosystem are related through feeding relationships. |
| energy pyramid | diagram that shows how energy decreases as it moves up through the trophic levels in an ecosystem, from producers to consumers. |
| detritivore | organism that feeds on dead plant and animal matter, helping to break it down and recycle nutrients in the ecosystem. |
| decomposer | organism, like bacteria or fungi, that breaks down dead material and waste, returning nutrients to the soil. |
| primary production | process by which plants and other producers create organic matter and energy from sunlight through photosynthesis. |
