As the time progressed, these microbial cells developed into more complex organisms

• TRUE

• FALSE

During the first 3 billion years, the earth’s atmosphere was rich in nitrogen and carbon dioxide.

• TRUE

• FALSE

Only ANOXYGENIC microorganisms have survived including methanogens- methane producing organisms.

• TRUE

• FALSE

Answer explanation

anaerobic

Phototrophic organisms or light-dependent organisms have survived as they get energy from sunlight.

• TRUE

• FALSE

As the production of oxygen in the atmosphere increases, this allowed multicellular life-forms to undevelop and evolve in increasing simplicities like the plants and animals that we have today
