sample is the population we make our study about them.
It is the number of units in a statistical study. The "population" need not refer to people. For example, when researching house prices in an area, the population would comprise all the houses in the area and the population size would be the number of houses.

Population, in statistics, is the entirety of units for which some variable information is collected for statistical purposes. "Population" need not have anything to do with people. For example, in a forestry study the population might be all trees in a given area, and the measured variable could be the species and/or ages of a selection (sample) of the population.
Statistics often requires one to make estimates of some measure (variable) about a set of units. The total number of such units is the population size. Note that population, in this context, need not refer to people. If the study is about household expenditure on food (in some area), then the population is all households and the population size is the number of households (in that area). If the study is about diversity of insects in a field, the population may be all 1-metre squares in the field, and the size of the population will be the number of such plots - which will equal the area of the field.

Population explosion of algae is called an algal bloom. These blooms can disrupt ecosystems by creating harmful effects such as oxygen depletion and toxins that can be harmful to other organisms.
We need to study about the history of Asia because of is contribution to world inventions, and given that it is the largest continent with the largest population size as well.
well, on my own idea, as what i have been observed, pre-marital sex, rape, and poverty are the main causes of population explosion.
The major factors that are responsible for population explosion are illiteracy, reduced mortality, increased birth rate, and an increase in life expectancy.
