Which of the following statements is true regarding autotrophs?

Autotrophs are organisms capable of producing their own food through processes such as photosynthesis or chemosynthesis. The statement about their ability to photosynthesize to produce their own food is accurate, especially for plants, algae, and some bacteria that utilize sunlight to convert carbon dioxide and water into glucose and oxygen. This capability distinguishes autotrophs from heterotrophs, which cannot produce their own food and depend on consuming other organisms for energy.

The mention of photosynthesis connects to the broader ecological role of autotrophs as primary producers in ecosystems, forming the base of the food chain and contributing to oxygen production and organic matter generation. Therefore, this characteristic is central to understanding the ecological and biological functions of autotrophs. Other statements do not accurately represent what autotrophs are or how they function.
