The organism that is an autotroph from the given options is the Pine Tree.
Explanation:
1. Autotrophs are organisms that can produce their own food through photosynthesis. They convert sunlight into energy for growth and survival.
2. Pine trees are examples of autotrophs because they have chlorophyll in their needles, allowing them to undergo photosynthesis.
3. During photosynthesis, pine trees use sunlight, carbon dioxide, and water to create glucose (sugar) for energy, with oxygen being released as a byproduct.
4. In contrast, mushrooms (option B) are examples of heterotrophs, which obtain nutrients by consuming other organisms or organic material.
5. Rabbits (option C) are also heterotrophs, as they need to consume plants or other animals to obtain energy for survival.
