Era is used to mark the boundaries of geological time scale by using radio carbon dating technique.
Explanation:
Geological time starts with Precambrian time.
Geologically, time is divided between the Precambrian era and present time into era.
The three eras are Paleozoic era, Triassic period and Cenozoic era.
Era is further divided into periods.
Scientists use radio carbon dating to study fossils and rock formation. With this study they were able to divide them in exact geological scale.
Geologic scale is the record of events in earth's history and evolution.
Cheetah is Carnivore
Tree is producer
The mushroom thingy is decomposer
Gazille is herbivore

Broken glass fragments can be very small and lodge in shoes, clothing, hair or skin. Gathering glass fragments from a crime scene can be valuable in determining end-use or connecting people and objects to places. For example, windshields have a different color and composition than a drinking glass or a lead crystal vase, so glass fragments on an individual’s clothing could be compared to those collected at a hit-and-run scene to determine if that individual was present.
