What's the life cycle of an organism?

In biology, a life cycle is a series of changes in form that an organism undergoes, returning to the starting state. "The concept is closely related to those of the lifehistory, development and ontogeny, but differs from them in stressing renewal."

The arrangement of the organisms in geological time order.

Trilobite

Armor fish

Catfish

Sauropod

Coyote

Explanation:

The "geologic time scale" allows people to know the chronological dating of events that occurred in Earth's history. The geologic time scale has been separated into areas, period and epochs.

Among the organisms above, the first one to appear is the "trilobite." They are considered the earliest group of arthropods. They were abundant in the "Age of Invertebrates." The second one to follow is the "Armor fish." They became popular in the "Ordovician" period. This was followed by the catfish since fishes became dominant in the "Palezoic era." Next, by the "Sauropod," a large-size dinosaur with a long neck. Dinosaurs flourished in the Triassic and Jurassic periods. The most recent organism among all is the "coyote." Coyote is a mammal and mammals appeared on Earth during the Tertiary period.

So, this explains the answer.
