Predator-Prey Interactions

Yesterday in class we recieved 2 sheets. One of them was called Carrying capacity. Carrying capacity is how many organisms can survive in an ecosystem. The other sheet was called Predator-Prey Interactions. On that sheet it told us that one species of animal can effect another population of animals.

Today in class we went over the questions on the Predator-prey interactions. We discussed ways in which the deer/wolf population could increase/decrease. For example, when the deer population would go up so would the wolf population a year later because there would be enough food for it. If the deer population went down so would the wolf population since there wouldn't be as much food. (see picture below)

Later in class, Mr. Banow gave us a sheet similar to the Predator-Prey Interactions sheet for marks. On this sheet we had to make a graph and answer the questions on it. We also found out we will be having a quiz tomorrow on limiting factors, ranom sampling, mark recapture method, and carrying capacity.

Next will be Shelby
