How could human activity disrupt the habitat and niche of an organism like the gray fox?
BlackZzzverrR [31]

Answer:

Disruption such as deforestation or mining can destroy the habitat, leading to water pollution, mud slides, and loss of soil. With the habitat affected, the animals the grey fox feeds on, such as rabbits or mice, will be affected as well, leading to the grey fox losing a source of food. By limiting the diet of the grey fox, other predators will be more likely to compete with the grey fox, disrupting its niche.

lana [24]

Answer:

amount of copper

Explanation:

<em>The independent variable would be the amount of copper fed into the experimental rats.</em>

An independent variable during an experiment is a variable whose value is not dependent on any other variable being measured in the experiment.

The value of an independent variable is not changed by any other variable in an experiment. In actual fact, the effect of the independent variable is being tested on other variables (dependent variables) in the experiment.

<u>Hence, in an experimental study of the effect of copper deficiency on coat color in rats, the amount of copper fed into the system of the rats will be varied and the effects of this variation on the coat color of the rats would be observed by measuring relevant variables. Therefore, the amount of copper is the independent variable.</u>
