8 of 10
death rate is expressed as the number of deaths per how many individuals per unit of time?
10,000
10
100
1,000

Explanation:

In wildlife population ecology (a subfield of Biology under Natural Science), the death rate (mortality rate) is commonly expressed as the number of deaths per 1,000 individuals per unit of time. This is a standard way to report mortality in population studies to make the rate understandable and comparable, as using per 1,000 is a practical scale for many wildlife populations (not too large or too small to interpret). The other options (10,000, 10, 100) are either too large (10,000 would make rates very small and hard to interpret for typical wildlife populations) or too small (10 or 100 might not capture the variation well in most wildlife population contexts).

Answer:

The correct option is: 1,000 (the option with "1,000" as the number of individuals for expressing death rate per unit time).
