<span>There are two types of reproductive strategies: r and k
r- strategy is the type of organism that makes alot of babies. They have limited to no parent care. They also have a high death rate, but matures rapidly. The growth curve would be exponential like X^2.
For example: Think r for RATS because even if you think you killed all the rats, there are constantly making more.
k-strategy is the type of organism that makes a single or few babies. The give alot of attention/parent care. They mature slow, and low death rate. The growth curve is sigmuodial. The have a limited to how much species live in that environment called the carrying capacity. Carrying capacity = maximum of # of population within an environment (food, living space, etc).
For example: Think K for Kangaroo. </span>
