Carbon is composed of three different isotopes 14C, 13C and 12C of which 12C is the most common and 14C (used for dating purposes) is only about 1 in 1 trillion atoms. 13C is about 1% of the total. Over the last few decades, isotope geochemists have worked together with tree rings experts to construct a time series of atmospheric 14C variations ...

Two species of shark may compete for water in the ocean, but the ocean is, you know, gigantic. So that's not what limits their population growth. Rather, the amount of food, like a specific fish that they both eat could be limiting, while other resources are plentiful.

ATP is a form of chemical energy, which is used to power different ionic channels in our body. However, it might be possible to use ATP indirectly if you made a nerve cell and put it into an area with enough protons. Protons can enter and exit a nerve cell rapidly. This movement triggers an electric charge. This charge signals to other nerve ...Population Ecology. A population is a group of interbreeding organisms that are members of the same species living in the same area at the same time. (Organisms that are all members of the same species are called conspecifics.) A population is identified, in part, by where it lives, and its area of population may have natural or artificial ...

After all the information is collected, ecologists can run the numbers and figure out for the grizzlies in Yellowstone a population of say, hypothetically 90 bears would have a 95 percent chance of surviving for 100 years. But if there were a population of 100 bears, the population would likely be able to survive for 200 years.
