Table two shows a couple of trends. The mouse population increases from quarter 1 to quarter 2 and quarter 2 to quarter 3 each year then decreases from quarter 3 to quarter 4. The overall mouse population is growing each year which can be seen by comparing the same quarter over each year and noticing that as the years increase, the mouse population also increases.

The population is increasing year to year, but this will not happen indefinitely because there will be more competition for resources between the mice and the mice predator population will increase since there are more mice to be eaten.

The change in season from warmer months to cold can reduce the population slightly since there is less available food and shelter once cold weather comes around

Yes, based on how the mouse population grows and diminishes, we can predict how the populations of other organisms within the mouse ecosystem may grow or diminish as a result of the mouse population

When they are plotted in a graph since each data point is combined and the trend can be seen immediately without comparing the exact values of each data point like you do in a table
