Answer 1
Combined terms with the correct definitions. 1. An organism that can produce its own food – Autotroph 2. A symbiotic relationship between two organisms in which one species benefits and no effect is apparent for the other species – Commensalism. 3. A cell that has a nucleus and/or membrane-bound organelles as its main feature – eukaryote. 4. The study of organisms too small to be seen with the naked eye – Microbiology. 5. A pathogenic organism – A pathogenic germ. 6. A unicellular or minimally cellular organism with chromosomes; can have both animal and plant characteristics – Protista. An autotroph is an organism that makes its own food from simple substances available in its environment. Autotrophs often use inorganic chemical reactions or light energy in the production of their food and are often the producers of 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 unaffected by it (neither advantages nor disadvantages).
