Question

Guppies living in a stream have a variety of spot patterns, some of which provide good camouflage against the stones in the streambed and others of which make them stand out against the background, allowing potential mates to see them more easily. If a predator that hunted by sight were introduced to the stream, what would be the most likely long-term consequence for the guppy population?

Answer 1

The population of the guppies will decrease.

Step-by-step explanation:

Answer 2

The population of the guppies will decreases.

Step-by-step explanation:

• In the stream the fine and specific spots of guppies make them visible to their mates.
• This is their survival and reproductive benefit.
• But the predator which prey the guppies by sight will easily catch them and the population of the guppies in stream will decrease.
• There will be another way in which guppies changes their spots for survival, in this case, their mates will not recognize them and the reproduction will decreases.
• Hence the consequence will be decease in population.
