They lived in the ocean because they were marine animals.
Earth is the planet with the most life forms.
The Earth's age is approximately 4.54 billion years. The major geological eras—Precambrian, Paleozoic, Mesozoic, and Cenozoic—represent varying percentages of this timeline. The Precambrian accounts for about 88% of Earth's history, the Paleozoic about 7%, the Mesozoic around 4%, and the Cenozoic roughly 1%. This distribution highlights that most of Earth's history occurred before the emergence of complex life forms.
we had the same question for homework. its paleozoic era it had alot of information in our textbook. and if you look on the geologic time scale it show you the Most information. hope this helped
Most extremophiles are simple, single-celled life forms, yet many are not. Extremophiles occur in all three domains of life: bacteria, archaea, and eukaryotes. ... However, archaea aren't restricted to extreme environments; they live in most of the same places as bacteria
The 4 eras are Cenozoic era, the mesozoic era, the paleozoic era, and the precambrian era.
The Precambrian life forms were less developed than the Paleozoic life forms.
The most significant difference is the complexity and diversity of life forms. Precambrian life forms were simpler and mostly consisted of single-celled organisms, while Paleozoic life forms were more complex, including multicellular organisms like plants and animals. Additionally, the Cambrian explosion during the Paleozoic era saw a rapid diversification of life forms.
The Precambrian life forms were less developed than the Paleozoic life forms. The Precambrian life forms were just starting to develop because this was 544 million years ago. that meant that things still needed to grow. This time didn't last very long though, due to the morphic and erosional processes. The Paleozoic Era began when organisms began developing new hard parts. This made it easier for fossils to be preserved.
yes
true. I think.
Earth is the planet with the most life forms.
paleozoic
During the Paleozoic era, Earth had a supercontinent called Pangaea, with most of the landmasses clustered together. The climate was warm and tropical, with high sea levels and extensive shallow seas. The era was marked by the diversification of life forms, including the emergence of complex marine and terrestrial organisms.
If you're talking about geological eras, they would be the Precambrian - beginnings of life, mainly ruled by bacteria Paleozoic - most basic body forms evolved like insects, amphibians, etc. Mesozoic - dinosaurs Cenozoic - humans
The sequence of the eras of Earth's history from oldest to most recent is: Precambrian, Paleozoic, Mesozoic, and Cenozoic. The Precambrian era comprises the earliest stages of Earth's formation, followed by the Paleozoic era known for the rise of complex life forms. The Mesozoic era is characterized by the age of dinosaurs, and finally, the Cenozoic era represents the current era with the dominance of mammals.
