Correct Option
The correct option is (a).
Explanation
In grassland ecosystems, both predators and prey have evolved specific physical adaptations to ensure survival. These adaptations include coloration for camouflage, eye placement for vision mechanics (depth perception vs. field of view), and anatomical features like claws for hunting or traction.
Statement-wise Analysis
- Statement 1 is Correct: Lions have a light brown or tawny skin colour. This coloration serves as camouflage, allowing them to blend seamlessly with the dry, brownish vegetation of grasslands. This helps them hide from prey while hunting.
- Statement 2 is Incorrect: Predators like lions have eyes placed in the front of their heads. This placement provides binocular vision, which is essential for accurate depth perception and judging distances when attacking prey. In contrast, prey animals (like deer) have eyes on the sides of their heads to allow for a wide field of view to detect approaching danger.
- Statement 3 is Incorrect: Lions have retractable claws. They can withdraw their claws inside their toes when walking. This adaptation prevents the claws from wearing out on the ground, keeping them sharp for hunting. Non-retractable claws are characteristic of the dog family (Canidae) or cheetahs (semi-retractable), which need traction for running rather than grappling.
Key Takeaway: Predators typically possess frontal eyes for depth perception and retractable claws to maintain sharpness, whereas prey animals possess lateral eyes for a panoramic field of view to detect threats.
