What type of organism is referred to as an autotroph?

• A. An organism that consumes other organisms for food
• B. An organism that produces its own food
• C. An organism that decomposes organic material
• D. An organism that absorbs nutrients from its environment

Answer: (B)

An autotroph is defined as an organism capable of producing its own food through processes like photosynthesis or chemosynthesis. Autotrophs utilize inorganic substances, such as carbon dioxide and water, and convert them into organic compounds, primarily through the absorption of sunlight or chemical energy. This self-sustaining capability is essential for the base of the food web, as autotrophs serve as primary producers, supplying energy and organic material to heterotrophic organisms that consume them. In contrast, other types of organisms carry out different modes of nutrition. Heterotrophs, for example, rely on consuming other organisms for energy and nutrients, while decomposers break down dead organic material and recycle nutrients within ecosystems. Nutrient absorption from the environment is characteristic of certain forms of life, such as fungi, which engage in a different method of obtaining sustenance than autotrophs. Thus, the defining characteristic of an autotroph is its ability to synthesize its food independently, which is reflected in the correct choice.
