WHAT IS A REPRODUCTIVE STRATEGY?
Animals have a variety of behaviour and ways to ensure that they are successful in reproducing in different environments, which makes them successful in the habitat in which they live.
Reproduction is the production of a new generation of organisms from an existing generation. It involves firstly the production of young, and then the growth and development of the young into mature adults. Reproduction is a life process that ensures the continued survival of a population.
