Answer :There was enough oxygen in the atmosphere to support a major burst of life on Earth
Explanation:
The Great Oxygen Event marks the time, approximately 2.5 billion years ago, when there was enough oxygen in the atmosphere to support a major burst of life on Earth
For the first half of the Earht's history, there was no oxygen in the atmosphere. It was inhabited only by single-celled organisms.Of those simple life forms, the cyanobacteria may have. evolved a way to take energy from sunlight, and used it to make sugars out of water and carbon dioxide. They used the same chemical process we know as photosynthesis. This released vast quantities of oxygen into the atmosphere and triggered the evolution of complex life.
The
statement that best supports that belief is “both have cell wall made
of cellulose, store food material as starch, and have chlorophyll a and chlorophyll
b”.
The green algae are a
large, informal grouping of algae consisting of the Chlorophyte and Charophyte
algae, which are now placed in separate Divisions. The land plants or
Embryophytes are thought to have emerged from the Charophytes.
