Wolves have kinetic energy, which is the energy of motion. This energy allows them to run, hunt, and interact with their environment. Wolves also rely on potential energy when they store energy by resting or preparing to hunt.
They eat food.
Wolves rely on the sun indirectly for energy by consuming prey that has obtained energy from the sun through photosynthesis. This energy is passed on through the food chain to wolves when they consume animals like deer or rabbits. Wolves do not directly rely on the sun for energy like plants do through photosynthesis.

The survival of wolves depends on the pack as a whole. It takes the team of them to bring down prey to eat and it takes the pack to watch after young wolves who are sometimes the future of the pack. They need to mark their boundaries so they can claim any prey that's inside their territory. The pack is basically what wolves need to survive as a whole.
The energy in the prey it eats. Wolves are carnivores, they eat meet. The animals they eat themselves eat grass and get their energy from the grass. Grass is a plant and plants make their own food by trapping the energy in Sunlight. Thus ultimately the Wolf's source of energy is the Sun.
Wolves are very active animals. Hunting, running, walking, and playing is how they stay active. It's rare to see a wolf stay in one place for a long time.
