Final answer:
A tree gets energy directly from the sun through the process of photosynthesis, where sunlight is converted into chemical energy in the form of sugars. This is why option C (Tree) is the correct answer.
Step-by-step explanation:
The organism that gets energy directly from the sun is a tree. This is because trees, and other plants, are capable of photosynthesis which is a process that converts sunlight into chemical energy. This energy is stored in the form of sugars, which the tree can use for growth and maintenance. Option A (Earthworm), B (Bee), and D (Hawk) are incorrect because these organisms obtain energy by consuming other organisms or organic matter. Earthworms are detrivores that consume decaying organic material, bees are herbivores that primarily feed on nectar from plants, and hawks are carnivores that feed on other animals.
