Final answer:
The statement that autotrophs cannot make their own food is false. Autotrophs, like plants, use photosynthesis to produce energy from sunlight, enabling them to be self-sustaining and supply energy to other organisms in food chains. Therefore given statement is false.
Step-by-step explanation:
Autotrophs are organisms that can make their own food, which is the opposite of the statement provided. Thus, the correct answer to the question 'Autotrophs are organisms that cannot make their own food' is false. Autotrophs use energy from sunlight or chemical bonds to convert inorganic molecules into organic material. The most well-known autotrophs are plants, which are photoautotrophs. They use the process of photosynthesis to harness sunlight and carbon dioxide, thereby producing their own energy in the form of carbohydrates. This not only allows them to sustain themselves but also supports other life forms, making them essential producers in global food chains.
