Population numbers for species were also recorded and graphed for each treatment (control and experimental). Based on the background and data provided, hypothesize whether Mytilus
would have an increasing or decreasing population trend over time. Provide a rationale for your response.



Answer :

Mytilus would have a decreasing population trend over time.

What is a control and experimental treatment?

In an experiment, the control group either receives no treatment, a standard treatment whose effect is known, or a placebo.

The experimental group also known as the treatment group, receives the treatment whose effect the researcher is interested in.

In the experiment on the effect of the presence of Pisaster on the population of Mytilus, the data obtained is given in the picture.

Based on the data obtained, it can be hypothesized that the population numbers for Mytilus would have a decreasing population trend over time.

In conclusion, the population of species change with changes in factors affecting population such as predators.
