Terms matched with the right definitions.

2. A symbiotic relationship between two organisms in which one species benefits and no effect is apparent to the other species – Commensalism.  

3. A cell that has a membrane-bound nucleus and/or organelles as its major characteristic -Eukaryote.  

4. The study of organisms that are too small to be seen with the naked eye - Microbiology.  

5.  A disease-causing organism - A germ pathogen.  

6. A one- or few-celled organism with chromosomes; may have characteristics of both animals and plants – Protist.


An autotroph is an organism that produces its own food from simple substances available in its environment. Autotrophs usually use inorganic chemical reactions or light energy in producing their food and are usually the producers in a food chain. Examples of autotrophs are plants and algae.


Commensalism is a type of relationship between organisms of two species where one organism benefits from the relationship and the other organism is not affected by it (neither benefits nor harmed).
