Population density is the aspect of population ecology of the black-tailed prairie dog does this statement describe.
Explanation:
Population density is the number of organisms are there in per unit area. It is used to measure geographical area occupied by organisms and its statistics.
In population ecology the structure, dynamics and contribution of population of species is studied. The idea of species distribution is studied in it.
The population density determines the number of species or members of particular population are present is a particular area.
An area of low density population will have more resources and more area per organism and less competition for resources and vice versa for high density population.
Prairie dogs have 12 adults per hectare of area this tells the population density of the rodents.

Answer:
<h2>There are two kinds of digestion;
</h2><h2>i) Mechanical and ii) chemical digestion. </h2>
Explanation:
There are two kinds of digestion;
i) Mechanical and ii) chemical digestion.
Mechanical digestion involves physically breaking down the food into smaller pieces. It begins in the mouth as the food is chewed.
In the Stomach
The stomach is a muscular sac with three important functions:
i) It mixes and stores food until it can be further digested.
ii) It secretes chemicals that help break the food into more digestible forms.
iii) It controls the passage of food into the small intestine.
Chemical digestion involves breaking down the food particles into simpler nutrients that can be used by the cells.
In stomach, chemical digestion of mostly proteins occurs Secretions from the stomach lining consist of about two liters of HCl, pepsin, and other many fluids that make up gastric fluids. The fluid is acidic and it helps kill bacteria and many other pathogens. It also produced by the stomach lining usually keeps the acids from damaging the lining. If no mucus or too much acid is produced, peptic ulcers form.
