dinosaur A term that indicates horrible lizard. These ancient reptiles lived from about 250 million years ago to approximately 65 million years back. All come down from egg-laying reptiles referred to as archosaurs. Their descendants ultimately divided into 2 lines. For numerous years, they have actually been identified by their hips. The lizard-hipped line are thought to have actually resulted in the saurichians, such as two-footed theropods like T. rex and the lumbering four-footed Apatosaurus(as soon as referred to as brontosaurus). A 2nd line of so-called bird-hipped, or ornithischian dinosaurs, appears to have actually resulted in an extensively varying group of animals that consisted of the stegosaurs and duckbilled dinosaurs. However a brand-new 2017 analysis now brings into question that characterization of relatedness based upon hip shape.
ecology A branch of biology that handles the relations of organisms to one another and to their physical environments. A researcher who operates in this field is called an ecologist.
environment The amount of all of the important things that exist around some organism or the procedure and the condition those things produce.
