Two different scientist.

Microbiologist

In biology, it is a huge discovery. While microbes such as bacteria, fungi, some algae, and protozoa had always existed always.

The first microbe that formed was in 3-4 billion years ago.

In 1673, Anton von Leeuwenhoek had put a couple of lends together and was able to see a complete different world. It wasn’t that amazing but scientist were now able to find the cure.

Marine biologist

A marine biologist can study anything that lives in oceans, wetland, fresh water or saltwater mix.

There are small living creatures that we can’t see always in the ocean. One of those small creatures are plankton, the primal part of the food chain.

There are three main types of algae, brown algae, green algae, and red algae. These algae can act like plants but different, mostly they are single celled form and they don’t have tissue.
