The answer is plankton are floaters. Plankton and nekton are both marine aquatic organisms. The main difference between the two is that plankton tend to float and be carried by water currents while nekton are organisms that swim against the current of the water. Plankton are passive swimmers while neekton are active swimmers.
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.
