Bean Plants

Plants with nitrogen-fixing bacteria in their roots make a good test bed for probing the give and take of biological partnerships. Bacteria Take carbohydrates and oxygen from the plant; in return, the microbes snag inert atmospheric nitrogen and convert it into a form the plant's cell can use.
Why then haven't the low output strains of nitrogen fixing bacteria taken over?
Because the nitrogen atmosphere forced bacteria in those areas to cheat on their symbiotic deal with the soybean plant. The plants seemed to retaliate for this outrage by reducing the supply of oxygen in those sections.

I think this was a good experiment because it involved beans and sometime i might do it myself

Pronghorn Ecology

In the early 19th century the pronghorn population has decreased due to over hunting and housing and land taking up and moving out . After many problems and not having enough pronhorns they decided to make a law that they shall not over hunt or even hunt them at all and not house up all the land by their cattle so grass can grow. After about 10 years the pronhorn population skyrocketed and they were back to a great population this is one of the best things they have done.
