What important role did blue-green bacteria play in the history of life on earth?
They performed photosynthesis and filled the atmosphere with water vapor.
Where does oxygen come from and why is it important to life on earth?
Oxygen is important as it the breathing sources. It also forms ozone which is vital for life on earth.
Why were bacteria and oxygen so important to the development of the rest of life on earth?
Bacteria played a crucial role in shaping Earth's early environment, particularly through processes like nitrogen fixation and decomposition, which enriched the soil and made nutrients accessible for other life forms. The advent of photosynthetic bacteria, such as cyanobacteria, significantly increased atmospheric oxygen levels, leading to the Great Oxygenation Event. This rise in oxygen not only allowed for the evolution of aerobic organisms but also paved the way for more complex life forms, including plants and animals, fundamentally transforming Earth's ecosystems. Thus, bacteria and oxygen were essential in establishing the conditions necessary for diverse and complex life to thrive.
When did bacteria form?
if you do not wash your hands and you touch so many thing bacteria froms to your hands
Do bacteria adapted better life on the earth than human beings?
Perhaps as bacteria have been around millions of years longer than humans.
Why are phytoplankton important to life?
phytoplankton provide most of the oxygen to earth.
Are phytoplankton important to life in the sea?
Yes, very much so.
Why is Phytoplankton important to life in the sea?
because it is at the bottom of the food chain
Are the bacteria the pionnering generations of life on earth?
Bacteria are usually considered as one of the pioneering generations of life on earth by the scientists.
Why are phytoplankton critical to life earth?
They produce much of the oxygen in the earth's atmosphere that aerobic life requires, and they are at the base of the food chain in most marine environments
What important role did blue-green bacteria play in the history of life on earth?
They performed photosynthesis and filled the atmosphere with water vapor.
Is bacteria the smallest form of life on earth?
yes.
What is the dominant life form on earth?
Cells/Bacteria.
What are two contributions of phytoplankton?
Phytoplankton form the foundation for most marine life food webs. Also they are responsible for half the photosynthetic activity on earth. My source was : http://www.ehow.com/about_5414740_importance-phytoplankton.html
Is there life on the red planet Mars?
No one knows for sure. sorry but not life as lik us may be some bacteria but not earth like life sorry but not life as lik us may be some bacteria but not earth like life
What was earth's first life forms?
bacteria is not right it is prokaryotes
Is life on Earth possible without bacteria?
no because bacteria helps digest our food and it also is one of the main decomposers.
