Population refers to the total number of all members of a species occupying a particular area or habitat at a given time. Populations are not static but change in size, structure and organization. Some of the characteristics of population are:
- Density which refers to the number of members of a species per unit area or volume.
- Dispersion refers to the spread and distribution of individuals of a species within a habitat.

The answers are pelvic girdle, sacrum, pubis, ischium, iilium , greater sciatic notch, acetabulum and obturator foramen respectively.
Figure is attached below.
<h3><u>Explanation:</u></h3>
Pelvic girdle is the largest complex bone system of human body. It's formed by fusion of 5 sacral vertebrae and 4 coccygeal vertebrae forming sacrum, the iilium, ischium, and the pubic bone. The iilium, ischium and pubis fuses to form single bone called os inominatum.
Two os inominata are joined with sacrum on both sides.
In the iilium, there are groves for the sciatic nerve which lets the sciatic nerve to pass from lumber region into the legs.
Acetabulum is the fossa for the head of the femur to get attached. It's formed by all the three bones.
Obturator foramen is formed by ischium and pubis through which passes the obturator nerve and obturator vessels.
