Answer: The correct answer is D. Natural disaster

The density dependent factors are those whose impact on the population growth is different with varying population density.

In the given options, A. Predation  B. Parasitism  C. Competition are density dependent limiting factor. This is because they all are dependent on population density. For instance, competition for food and other resources is high when there is large population in a particular area.

On the contrary, Natural disaster is not a density-dependent limiting factor. This is because its impact is not dependent on the number of individuals. For example- Earthquake is a natural disaster, which causes damage to all the life forms irrespective of the population size.

Thus, in an ecosystem, Natural disaster is not a density-dependent limiting factor.

Dmitry_Shevchenko [17]

Answer:

See the answer below

Explanation:

It may seem that the question is incomplete. The complete question reads:

Match each statement to the type of behavior it describes. Jenna published the results of her latest experiment for the public to see. Malcolm altered an experiment to be able reach his desired conclusion. Elena keeps complete records of all her experiment results. Neal shared the results of his field study even though they didn’t support his hypothesis. <em>Put each description to the group it belongs to. 1.Responsible 2.Irresponsible.</em>

<em>To answer the question:</em>

<em>Responsible behavior</em>

  • <em>Jenna published the results of her latest experiment for the public to see.</em>
  • <em>Elena keeps complete records of all her experiment results.</em>
  • <em>Neal shared the results of his field study even though they didn't support his hypothesis.</em>

<em>Irresponsible behavior</em>

  • <em>Malcolm altered an experiment to be able to reach his desired conclusion</em>

Responsible behaviors are those that support responsible scientific practices and do not jeopardize the objective nature of research. Every data during experiments must be well kept and after thorough analysis, results must be published fro the public to see irrespective of whether it agrees or disagrees with the original hypothesis.

Altering an experiment in order to achieve the desired result is grossly irresponsible, as this eliminates the objectivity that should be the main goal of every experiment. Bias must be eliminated from every scientific experiment.
