Question

Pick the correct statement from the following:

• A. Cows and sheep are arboreal as they eat the leaves of trees.
• B. Birds have strong legs that help them to move around on land.
• C. Non-aerial birds spend most of their lives on land.
• D. Scavengers are always terrestrial animals.

Answer 1

The correct option is C Non-aerial birds spend most of their lives on land.

• Cows and sheep are terrestrial herbivores, i.e. they live on land and eat grass off the ground. They do not live on trees. So, they are not arboreal animals.


• Birds have weak legs and light hollow bones which make easy for them to fly without falling down.


• Scavengers are the animals that mostly eat dead and decaying animals. They could be terrestrial animals like hyenas, or aerial animals like vultures. So, scavengers are not always terrestrial.


• Non-aerial birds are the birds that cannot fly. So, they have to live on land to survive.
