Which of these statements is true about autotrophs, but not heterotrophs?

Autotroph are the organisms which makes their own food such as plants. Plants make their own food in the process of photosynthesis. They use carbondioxode and water in the presence of sunlight produces glucose and oxygen.

Heterotroph are the organisms which are unable to make their own food. They feed on other animals for uptake of energy. All animals except plants and algae are heterotroph.

its probably to later but whats the question

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!
