Question: 1 / 400

What is the term for an organism, like a green plant, that nourishes itself by making organic materials out of inorganic?

Autotroph

An autotroph is an organism that is able to produce its own food through photosynthesis or chemosynthesis, using inorganic substances such as carbon dioxide and water. This allows autotrophs, like green plants, to be self-sufficient for their energy and nutrient needs. Option B, auxin, is a plant hormone involved in growth and development, but it is not related to nutrition. Options C and D, bacillus and bacteria, are types of microorganisms that can be autotrophic, but not all bacteria and bacillus are autotrophs. Therefore, A is the most accurate term for an organism that nourishes itself by making organic materials from inorganic substances.
