Answer:
(B) Boreal owls range over larger areas in regions where food of the sort eaten by small mammals is sparse than they do in regions where such food is abundant
Explanation:
Living beings exhibit various changes in the behavior and niche to make themselves better fitted to the conditions of their habitats.
Boreal owls feed on the other smaller mammals such as mice and shrews. These organisms that serve as their prey are relatively less abundant in the habitat. To ensure the food availability, the boreal owls occupy a larger area so that they can catch their less abundant food organisms.
In the habitats where the prey species of boreal owls are present in a larger number, these owls occupy smaller regions since the food organisms are easily available.
Explanation:
The statistical study of populations and how they change over time is called demography. Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume.
<span>The trouble with identifying bacteria is that a lot of them look exactly the same. So, identifying by shape and such will only get you so far. However, two kinds of bacteria that look exactly the same under the microscope could have very different physiologists. One may be able to use a certain sugar as an energy source while the other one cannot, for example. Therefore, you can use morphology (physical characteristics) to narrow down the possibilities, but then you must complete the identification using the bacteria's physiology.</span>
