Some people do not even have the knowledge about the ecosystem and how it affects the world we live in, and then there are those people that just do not care about the ecosystem. An ecosystem is a community of animals, people, and plants that interact with one another and their physical environment. One type of ecosystem that we take for granted is animals. Many animals are becoming extinct as the years go by.
As I briefly mentioned in the previous paragraph, an ecosystem is a worldwide community where people, plants, animals interact with one another in their physical environment.

Alan Brown in his article Dinosaurs. The word “dinosaur” originates from Greek that means “terrible lizard”. The Mesozoic era is divided into three approximately equal length of times periods, Triassic, Jurassic, and Cretaceous.

Ornithischians meaning 'bird hip joint ' in Greek, is the other classification of dinosaurs, ornithopods were one of the earliest ornithischians. Some of the last dinosaurs to develop were the “horned dinosaurs,” or

During the Triassic period (250- 200 million years ago) there was one humongous supercontinent named Pangaea. There was mainly vegetation around the edges of Pangaea since Pangaea was so big and the inland zones were long way from the ocean. Therefore, the first of the dinosaurs lived neared riverbanks and near the sea, water for source of life. By the Jurassic time period, two hundred million to one-hundred forty five million years ago, the supercontinent Pangaea was breaking up, causing water to go through the continent developing forests and more plants. During the Cretaceous period, one-hundred forty-five million to sixty-five million years ago, Pangaea was separated into many continents, much like the continents of today. This created more dinosaurs to roam more of the land and began to live everywhere, and to differentiate the dinosaurs, depending on their habitat.
There are numerous theories of how the dinosaurs went extinct, but one of the most accepted theories is a comet came crashing down to earth, blocked sunlight and formed of a cloud of dust, destroying plants the dinosaurs depended on. Another extinction theory is the greenhouse effect. It has been debated that the decrease of the seas that occurred during the Cretaceous period caused a reduction of marine plants. Consequently,
