Explain the four factors that produce changes in population size. Which factors are affecting the population size in the video?

Which video?

I suggest you watch the video rather than trying to mooch answers from someone else who may be taking your class.

Hmmmm. Did you see a video on this? Did it discuss four factors?

My training tells me that factors which affect population size are:

availability of food,
environmental (temp, space, water, etc)
birth rate vs death rate
predators

These may or may not have been given to you.

The four factors that produce changes in population size are birth rate, death rate, immigration, and emigration.

1. Birth rate: This refers to the number of births within a population over a specific period of time. It plays a crucial role in population growth, as a high birth rate can lead to an increase in population size.

2. Death rate: This is the number of deaths within a population over a specific period of time. A high death rate can result in a decrease in population size, as more individuals are dying compared to the number being born.

3. Immigration: Immigration occurs when individuals move into a particular population from another area or country. This can contribute to population growth, as the number of individuals entering the population exceeds those leaving.

4. Emigration: Emigration is the opposite of immigration; it refers to individuals leaving a population to move to another location. The departure of individuals from a population can lead to a decrease in population size.

To identify which factors are affecting the population size in a video, you would need to observe and gather data about the birth rate, death rate, immigration, and emigration. Analyzing these factors will allow you to determine their impact on the population size depicted in the video.
