Answer 1

Hint: Among the diverse number and types of organisms on this earth, there are various organisms that have a particular habitat. This could either be land or water or both. They choose their habitat depending on their requirements and body structure.

Step by step answer:The classification on the basis of birth-giving, there are 2 types of animals-
Egg-laying animals- these are the ones which lay eggs which on hatching give rise to new young ones.
Mammals- they are the animals that develop the baby in their womb for some specific time and then deliver their young ones. They feed their child with the milk from the mammary glands.
Option A: Ostrich: ostrich egg is known to be the largest cell as it is the single-celled egg.
Option B: Snake: The snake’s egg size can range from 1 inch to 5 inches. They are leathery rubber-like resembling a big thick rice grain.
Option C: Human: Humans are mammals which give birth to their young ones. They do not lay eggs. They develop their child in the female’s womb for a particular amount of time.
Option D: Shark: The eggs of sharks can vary from 2 inches to 4 inches which are most likely to have size
like that of snake eggs. The largest animal being the Blue whale, it gives birth to the young ones.
So the answer is option A: Ostrich

Note: Mammals give training to their young ones. They protect them until they are strong enough to protect themselves. Mammals are warm-blooded, which means they cannot change their temperature on their own. They can have hairs and fur.
