We are learning to: describe how asexual reproduction increases or decreases chances for survival. We are looking for :Increases survival: due to no variation, it allows for survival in a stable environment.

Decreases survival: due to no variation, the organism is not able to adapt to a changing environment.

Paramecia usually reproduce asexually. Fish reproduce sexually. Suppose the environmental conditions in the lagoon change. What advantage will

the fish populations have over the paramecium population?
