Reproduction is essential for the survival of species. Mammals are a group of animals that give birth to live young. Some animals do not care for their eggs or young ones.

Explanation:

Reproduction refers to the process by which organisms produce offspring. Animals reproduce young ones to ensure the survival and continuation of their species. Animals reproduce through two main ways: sexual reproduction and asexual reproduction.

Mammals are a group of animals that give birth to live young ones and nurse them with milk. Examples of mammals include humans and dogs.
