Who is the powerful animal of forest?

There's no single answer to who the "most powerful animal of the forest" is! It really depends on what you mean by "powerful":

* Physically powerful: This could be the bear, known for its strength and size, or the bison, known for its massive horns and sheer power.

* Predator power: The wolf, with its pack hunting skills and intelligence, could be considered the most powerful predator. However, the tiger or lion (depending on the forest location) are also formidable predators.

* Influence on the ecosystem: The beaver, through its dam-building abilities, can profoundly impact the entire forest environment, making it arguably the most powerful in that sense.

* Intelligence and resourcefulness: The monkey, known for its intelligence and ability to use tools, could be considered powerful in its own right.

Ultimately, the "most powerful animal" is subjective and depends on your criteria!
