A newly discovered animal reproduces slowly. It has only one offspring each time it reproduces. Which reproductive strategy does
Marizza181 [45]

Answer:

C: K Strategy

Explanation:

The best choice will be C- K strategy because this type of strategy involves greater investment from parents into their offspring. These organisms are mostly higher organisms which reproduce slowly and ensure the maximum survival of their offspring. They compete strongly with other organisms and invest more in their survival by producing fewer quality offspring that have more survival opportunities.

Example of K-selected species include  larger mammals (such as primates and horses), birds and larger plants. Unlike their opposite R-selected specie which produce large number of offspring, K selected specie are called in Equilibrium wile R-selected species are called as opportunistic.

Thank you!
