Welcome to the Biology Tips Daily - give us a minute and we share with you one tip a day.
A good deal of the cellular machinery, anatomy, physiology, and behavior biologists study is devoted to the production or acquisition or conservation or use of energy. After all, it all comes to a screeching halt without enough energy. So whatever aspect of biology you are studying may involve energy either directly or indirectly.
How can a 500 kg crocodile survive, grow, and thrive when it routinely eats less than a 50 kg teenage boy eats over the course of a year? Why is there a thing in your cells that has its own molecules and also reproduces independently of your cells as if it's a stealth creature? Some humans have the unique capacity to store large amounts of fat in their buttocks. Some bacteria can enter a state of "suspended animation" for hundreds or perhaps thousands of years.
Why do the savannahs of East Africa support huge numbers of organisms while that icy desert, Antarctica, supports so few? Wolves can chase their prey for dozens of miles and cheetahs are hard pressed to chase their prey for more than a mile. Elephants routinely communicate with one another over very long distances without the benefit of cellular technology or the internet. How? Why do so many groups of complicated chemical reactions in cells produce the same molecule? Why do you breathe O2 rather than N2, after all there's a heck of a lot more nitrogen than oxygen in the air?
The answer to these questions or explanations of these observations has to do with energy, directly or indirectly. Keep energy in mind to think like a biologist.
Until then, stay tuned for more biology tips.
