1. Describe how the amount of food or amount of space available might influence the size of a population of organisms.

It would make it a lot bigger. More the food you have would make more yeast cells. That would make a lot of space. More space went down from day 1 to day 3. In our experiment it dissolved as the days went on. So yes there would be more space taken up.

2. In a laboratory, yeast can be grown in a very controlled setting without many external influences on their population. In nature, however, conditions are constantly changing. Using what you know about population dynamics, describe what might happen to a population of organisms if the climate where they live changes.

If the climate changes then the food does to. If there …show more content…
On day 2 are test results were 8. The next day it was 130. On day one are control/test was 5 and 7. It got bigger each day when the space got bigger then your food does to. Like in real life when space gets bigger you are able to grow more stuff in that space.

5. Scientists often look for patterns when they are investigating the world. Explain why identifying patterns in the world is helpful, using an example from your investigation about population growth.

It is important because if you keep getting the same thing everyday even though you are expanding your space something is wrong. When are control went to 80 on day 3 then are food rose to 130. That is one example on if your space change then your food will grow to. So if you expand your space and you are getting the same thing everyday then something is not right. You should be making more food a day. So that is how patterns are important.

6. Understanding how living things go through periods of stability followed by periods of change is important for scientists. Explain why understanding the relationship between stability and change is important, using an example from your investigation about population
