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.
