Well out could give the baby birth defects or STDs. I think
Charles Darwin used domesticated animals to provide evidence for evolution by natural selection by showing "<span>Differences between breeds show that selection can cause species to change."</span>
The question that most likely relates to the ecologist's observations and collected data is, 'Are fish dying due to reduced oxygen in the water?'
<h3>Research questions</h3>
Research questions are usually coined from observations. Observation is the first step in the scientific method. Once the research questions have been formed, hypotheses follow.
In this case, the ecologist, who happens to be the researcher in this case, observed that fishes were dying in large numbers. Fortunately for the researcher, he also observed that the lakes around the city where fishes were dying had significant algae growth as well as reduced oxygen levels.
The right questions to ask, therefore, should try and relate to observations together.
Thus, linking the death of the fishes to reduced oxygen levels in the lakes is the right question to ask.

There are two modes of population growth that are:
Exponential curve and the Logistic curve, exponential curve is also known as
J-curve and logistic curve is also known as S-curve. When there is no limit of
population growth, exponential curve occurs.
Linear growth occurs when population growth slows or stops
after a period of exponential growth and it <span>is the type of growth which occurs
after a significant and exponential increase in population.</span>
