Final answer:
Trees are true autotrophs as they are capable of photosynthesis, which allows them to produce their own food using sunlight and carbon dioxide.
Step-by-step explanation:
Trees are indeed autotrophs, and the statement that they prepare their own food through photosynthesis is true. The term autotroph comes from the Greek words for 'self' (auto) and 'feeder' (troph), meaning these organisms can produce their own food. In the case of trees, they are classified as photoautotrophs, a type of autotroph that harnesses sunlight along with carbon dioxide to create carbohydrates, which serve as their chemical energy source. This process of converting light energy into chemical energy is known as photosynthesis. It is not only trees that are capable of this but also other plants, some bacteria, and algae. These autotrophs play a vital role in ecosystems as primary producers and are essential for the survival of heterotrophs, which are organisms that cannot produce their own food and instead rely on the food produced by autotrophs.
trees are autotrophs and prepare their own food through photosynthesis. Autotrophs are organisms that can produce their own food, and plants are the best-known autotrophs. They use sunlight and carbon dioxide to synthesize carbohydrates through the process of photosynthesis.
