In class, over the last days my class and I have been studying about.ecology.Some of the topics included in this were populations, needs for an organism, ecosystems and the study of population. The study of population we were concentrating on was mark and recapture. This method is usually used with animals that aren't as visible, for example turtles. Ecologists and scientists go on the seas, capture the turtles and mark them in a way. The next year they would come back. recapture the turtles, and see how many new ones have arrived and if any turtles with the marks have dissapeared. In this specific project thought, we were counting rabbits. Populations are affected by deaths and new comers, in other words, death rates and birth rates. The instructions for this project were to start out with 2 beans representing the rabbits, and every pair of rabbits gives birth to 2 others every year. Having this information we had to add beans until year 5. I noticed that each year the rabbits were doubling, and once I put my information on a graph and table, I saw that the answers are all answers you could get from powers of 2. So after all, if the birth rate of the rabbits would continue like this, we could get the answer just by finding out powers of 2. These are 2 graphs which we created out of our data:
