Answer:

Introduction:
Among the given options, the correct answer is option 'D', which is the eagle. Eagles have sharp eyes that enable them to see their prey on the ground. Let's explore why eagles have such keen eyesight and how it helps them in hunting.

Eagle's Vision:
1. Sharp Eyesight: Eagles have one of the most extraordinary eyesights in the animal kingdom. They have excellent visual acuity, meaning they can see small details from a long distance.
2. High Number of Photoreceptors: Eagles have a higher number of photoreceptor cells in their eyes compared to humans. These cells, called cones, are responsible for color vision and visual acuity.
3. Large Eyes: Eagles have large eyes, which allow more light to enter and provide a wider field of view. This helps them keep an eye on their surroundings and detect prey from a distance.
4. Binocular Vision: The eyes of an eagle are positioned on the front of its head, providing binocular vision. This means both eyes work together to focus on a single object, allowing for better depth perception and accurate judgment of distances.

Hunting with Sharp Eyesight:
1. Spotting Prey: Eagles use their sharp eyesight to scan the ground for potential prey. They can spot small animals, such as rodents or fish, from great heights.
2. Detecting Movement: The keen eyesight of eagles helps them detect even slight movements on the ground. This allows them to locate and track their prey effectively.
3. Planning Attacks: Once an eagle spots its prey, it uses its sharp eyesight to assess the situation and plan its attack. It can determine the distance, speed, and trajectory required to catch the prey successfully.
4. Targeting Weaknesses: Eagles can identify the weak or vulnerable spots of their prey, such as injured or slower animals. They use their sharp eyesight to ensure a precise strike on these weak points.

Conclusion:
Eagles possess exceptional eyesight, thanks to their sharp visual acuity, high number of photoreceptor cells, large eyes, and binocular vision. This remarkable vision helps them spot their prey on the ground, detect movements, plan attacks, and target weaknesses. As a result, eagles are highly skilled hunters and can successfully catch their prey with great precision.
