Living Together LS3
How does water quality affect the ecology of a community?
| Term | Definition |
|---|---|
| ecosystem | All the living things in a given place, along with the nonliving environment. |
| abiotic | The nonliving parts of an ecosystem. |
| biotic | The living parts of an ecosystem. |
| habitat | The place where an organism lives and grows naturally. |
| community | Groups of organisms living together in a certain area. The organisms interact and depend on one another for survival. |
| niche | What an organism does, why it lives where it does, and how it fits into its surroundings. |
| aquatic ecosystem | An ecosystem located in a body of water. |
| diversity | Difference (in this case, the different types of animals). |
| abundance | The amount (in this case, the number of a type of animal). |
| classify | To arrange or sort by categories. |
| macroinvertebrate | An organism that does not have a backbone and can be seen with the naked eye. |
| dichotomous key | A key used to identify living things. |
| cell | The structural and functional unit of all living organisms. It is sometimes called the “building block” of life. |
| taxonomist | A scientist who classifies organisms by characteristics. |
| species | A group of organisms that look alike and can breed with other members of the group and produce fertile offspring. |
| ecologist | A scientist who studies the relationships between organisms and their environment. |
| biotic indicator | An indicator that an organism is or was alive (could be a fossil). |
| photosynthesis | The process in which sugar and oxygen are produced by green plants and some other organisms using water, carbon dioxide,and energy from sunlight. |
| carbon dioxide | A colorless, odorless gas commonly found in air; carbon dioxide is used by plants in the process of photosynthesis. |
| glucose | A type of sugar. It is the main source of energy for living organisms. |
| sugar | A chemical compound produced by plants during photosynthesis. Sugars provide a source of energy used by living organisms. |
| oxygen | A colorless and odorless gas produced by plants during photosynthesis and used by animals for respiration. |
| chlorophyll | A green substance found in plants that is used to capture energy from sunlight during photosynthesis. |
| cell respiration | The process by which food and oxygen are converted to energy; carbon dioxide, and water in a living cell. |
| producer | An organism capable of making its own food. |
| herbivore | An organism that obtains its food only from plants. |
| carnivore | An organism that obtains its food only from other animals. |
| predator | An organism that hunts and kills other organisms. |
| population | A group of organisms of the same species that live in a particular location. |
| parameters | The limits or boundaries (in this case, values). |
| pesticide | A chemical used to prevent bugs from destroying crops. |
| detritivores | Organisms that feed on dead plants and animals. |
| food web | A series of interlocking food chain. |
| law of conservation of matter (or mass) | A law of physics that states that matter (or mass) cannot be created or destroyed; it can only change form. |
| law of conservation of energy | A law of physics that states that energy cannot be created or destroyed, it can only change form. |
