Answer:
A. Populations were separated through geographical isolation.
Explanation:
It states that, for a given mass of an ideal gas at constant pressure, the volume is directly proportional to its absolute temperature, assuming in a closed system.
p1/t1=p2/t2
The population of the ground squirrels will be limited by the population of the hawks. The population of the hawks, thus, will be a limiting factor for the population of the ground squirrels. The Hawks are the birds of prey that feeds on squirrels. With the increased number of hawks in the same area as them will put these squirrels in danger. The population of the tree squirrels, however, will have no affect on the population of the ground squirrels. The genetic variability and breeding season are not limiting factors for their population either.
Hence, the correct answer is 'option B - a population of hawks'.
<h2>Ecological Footprint - Option C</h2>
An ecological footprint is determined by measuring the rate of water used. The Ecological Footprint is determined by following how much biologically prolific field it needs to consume a population's carbon dioxide radiations and to produce all the means it absorbs.
A country's consumption is measured by summing imports to and deducting exports from its nationwide generation.
