Detailed explanation-1: -Ducks have webbed feet, i.e., their toes are joined together by a thin flap of skin. These help them to swim easily in water. The feathers on the body of ducks are covered with an oily layer to make them waterproof. So, their body is always dry and warm.

Detailed explanation-2: -Their webbed feet help them to swim and to keep their balance on muddy riverbanks, while their bills have small bristles that filter food from the water. The outer layer of feathers is extremely waterproof and keeps the underlayer dry when they dive.

Detailed explanation-3: -Which best represents an adaptation that allows ducks to survive in aquatic ecosystems? Ducks have waterproof feathers.

Staying dry helps ducks stay warm and also decreases their body weight, which improves movement through the water and the air. Color is another common adaptation.

Detailed explanation-5: -Their webbed feet are uniquely designed to help them move through the water. A duck’s foot has the ability to become wider. Ducks use their webbed feet like paddles to provide more surface to push against the water.
