The red fox is a predator which feeds on the small mammals, amphibians, insects, and fruit. Red foxes are active at night. They
provide blood for blackflies and mosquitoes, and are host to numerous diseases. The scraps, or carrion, left behind after a fox's meal provide food for many small scavengers and decomposers. Is this an example of the red fox’s habitat or niche? Explain your answer.
In a mammalian brain, there are four major lobes that are present and one of them is the frontal lobe.
The frontal lobe is mainly rich in dopaminergic neurons and thus, it is mainly concerned with functions such as memory, reward, motivation, planning, attention, etc.
The process of break down of tissues and cell death in the tissues is referred to as atrophy and since the frontal lobe is associated with the functions as mentioned above its atrophy would lead to a slow decline in these functions.
Since Mr. Klondlike behavior is changing his blunt comments are most likely a result of atrophy of the frontal lobe.
It's a normal part of nature, and one of many ecological factors that help keep the hundreds of thousands of living plants. It also keeps animals in balance with one another.
