Population

Population: A population is a group of organisms of one species that live together in one area. In this photo you see a population of grass. This is a population because the grass is a living organism of one species that all live in this area. So, this photo reveals a group of grass organisms that reside in one place, a population.

Adaptation of a Plant

Adaptation of a Plant: This is a photo of a Paperbark Maple I took while at the Harvard University Arnold Arboretum. The definition of adaptation is when a living thing adjusts or modifies itself to suit new conditions. In this photo of the tree you can see a visible adaptation of the bark peeling off. This is a specific adaptation that helps the tree protect itself from harmful things in its environment; the exfoliating bark allows it to get rid of any parasites on the tree. This is an adaptation of a plant because the tree had to make a response in order to deal with the herbivory of bugs and many other harmful factors.

Homeostasis

Homeostasis: This is a photo of a dog I took while at the class trip to the Arnorld Arboretum. As you can see in the photo the dog is panting for air because it just arrived from running to its owner. This is a perfect example of homeostasis because the dog is trying to maintain internal stability. Because of the hot weather the dog pants in order to cool itself down and balance its internal temperature. The dog lacks sweat to cool itself down so it breathes in cool air in order to cool its body down. ( In the photo I was unable to put my identifier, by the time I tried to retake the picture the dog was long gone).
