I dont think its possible for the population to decrease because if people keep on having babies the population is just going to grow larger than what it was before.
I guess it is if you are in war or your country is tortured by a disease. Then many people will be killed in war/get infected and die. After that even if the birth rate is high, the death rate would be higher so the population will decrease in size. It is possible. (Sorry for not professional answer.)

If more people were dying than being born, then yes
If more people were dying than being born, then yes
Yes, if the population is dying out faster than new members are being born. Disease and warfare can be two reasons why this might happen.
A population can change over time due to factors like birth rate, death rate, immigration, and emigration. High birth rates can lead to population growth, while high death rates can lead to a decline. Immigration can increase the population, while emigration can decrease it. Environmental factors, public health policies, and socio-economic conditions can also impact population changes.
When a population pyramid has a wide base and is narrower at the top, it indicates a high birth rate and high population growth. This kind of pyramid is typical of developing countries where a large proportion of the population is young and the birth rates are high.
Population implosion refers to a rapid and drastic decline in the population of a region or a country. This can be caused by factors such as low birth rates, high death rates, and emigration. Population implosions can have significant social and economic consequences, such as labor shortages and declining economic growth.
Population can decrease by a huge disease for example loads of people died from small pox. But such a disease is very uncommon as we have many vaccination's. Also if nuclear war starts huge amounts of people will die.
