Answer: microfossils help us decode the climate and what the ecosystem was like in the past.
Explanation:
Fossils are any remainder or evidence of an organism that lived long ago. The preserved remains of living beings or their traces of the past are documents of the history of life on planet Earth.
Depending on their size, they are classified as microfosiles or macrosophiles.
Macrophiles are visible sized fossils, such as bones, shells or petrified wood. While the microfossils are seen with the microscope. They are important for correlating sedimentary layers, when looking for oil, and they help us decipher the climate and what the ecosystem was like in the past. Examples of microfossils are diatomaceous, radiolaria and foraminifera.
