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.  
🗑

🗑
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.  
🗑
