Question

a particular habitat, a prey animal has two sources of food. one source is found in the water. the other source is found on land. if the main predator n land, what is the most likely structural adaptation that will be favored in the population of this prey animal?
● increase in visual acuity
● increase in jaw size
● increase in leg strength
● increase in webbing between toes

Explanation:

• An increase in visual acuity (\(increase\ in\ visual\ acuity\)) would help the prey animal spot predators from a distance, which is crucial for survival.
• An increase in jaw size (\(increase\ in\ jaw\ size\)) is more related to feeding rather than escaping a predator.
• An increase in leg strength (\(increase\ in\ leg\ strength\)) would help in running on land but not in water.
• An increase in webbing between toes (\(increase\ in\ webbing\ between\ toes\)) is good for swimming but not as effective on land for escaping a land - based predator.

Since the main predator is on land, being able to see the predator early (increase in visual acuity) is the most important adaptation for the prey animal that has food sources in both water and land.

Answer:

increase in visual acuity
