Population of Rabits




During Science class, we talk a lot about population, population growth, population density, and also endangered animals. Population means,the total number of persons/individuals inhabiting a country, city, or any district or area.We had a rabbit population growth project. In this project we had to counted a rabbit population in five years, but instead of rabbits we used beans. As you can see on the table and graphs, in year 0, there was only one male and one female rabbit, in year 1 they got again one male and one female little rabbit. In the next year, they both got a male and a female rabbit, so each year a pair reproduced and formed 2 more rabbits. We had calculated up to the tenth year first and we realized that the population changed from 2 rabbits in year zero, to 2048 rabbits in year ten, the population grows very fast. I realized that every year the number of rabbits doubles. We didn't do it our brains, we had a visualization of it but only using beans not rabbits, that made us understand better. This was very interesting for all sorts of reason. First for me i saw that even if the animal isendangered, its population can still grow back to a large number again, that is of course if they live in the right place, under good conditions and without humans hunting and killing them. Also the species needs to reproduce a lot and fast since while new rabbits are born, other ones are dyeing. This little project helped me to see, how sometimes the population of animals can can grow very fast, I hope you also got that out of my blog post.
