Cyanbacteria, or blue-green algae. At least that is the current belief shared by most scientists.
My source: An article in a magazine called "Science Illustrated", Volume 5, Issue 5, entitled "Seeing photosynthesis in a new light". Their main point in the article is that cyanbacteria in it's current form has a more efficient type of chloroplast with better enzymes that they want to engineer into agricultural plants, but the mention of cyanbacteria in an older form as the first organisms to use water splitting photosynthesis is also in there.

Did organisms that require oxygen exist before photosynthetic organisms?
It would be impossible for oxygen requiring organisms to exist before photosynthetic organisms because there was not oxygen in the atmosphere for these organisms to breathe. Photosynthetic organisms take carbon dioxide and water in and create oxygen as waste. Before these photosynthetic organisms existed there was not enough or any oxygen in the atmosphere for organisms requiring oxygen to survive.
Photosynthetic organisms take in what from the atmosphere and combine it with water and energy from the sun to form sugar?
Carbon Dioxide
Where are green algae or other photosynthetic organisms likely to thrive in the ocean?
sunny water that is rich in nutrients.
What does plants and other photosynthetic organism such as algae take in?
Plants and other photosynthetic organisms such as algae take in ________ from the atmosphere and combine it with water and energy from the sun to form sugar.
Is Plants and other photosynthetic organisms are producers in ecosystem?
A photosynthetic organism is one which engages in photosynthesis, which is the creation of sugar using the energy of sunlight along with the catalyst chlorophyll, and using carbon dioxide and water. These are green plants, as well as cyanobacteria.
Why can't photosynthetic organisms grow in the deep water zone?
Photosynthetic organisms need light in order to survive. In very deep water there is no light.
Did organisms that require oxygen exist before photosynthetic organisms?
It would be impossible for oxygen requiring organisms to exist before photosynthetic organisms because there was not oxygen in the atmosphere for these organisms to breathe. Photosynthetic organisms take carbon dioxide and water in and create oxygen as waste. Before these photosynthetic organisms existed there was not enough or any oxygen in the atmosphere for organisms requiring oxygen to survive.
What region can photosynthetic organisms not live in?
In order to live, photosynthetic organisms cannot survive without sunlight and water. Therefore a photosynthetic organism cannot survive in any place without water, such as a desert, or without light and air, such as the moon.
Is dinoflagellantes photosynthetic?
Most dinoflagellates are marine plankton though they are also abundant in fresh water habitats. These organisms are known as photosynthetic.
Plants and other photosynthetic organisms such as algae take in from the atmosphere and combine it with water and energy from the sun to form sugar.?
Plants and other photosynthetic organisms such as algae take in ________ from the atmosphere and combine it with water and energy from the sun to form sugar.
Algae and other tiny organisms that live in water are classified as?
Algae and other tiny organisms that live in water are classified as plankton. Plankton are important members of aquatic ecosystems, serving as a food source for larger organisms and playing a role in nutrient cycling.
Where is the first living organism on earth in air or land water atmosphere?
The first living organisms on earth were a type of aquatic photosynthetic bacteria called cyanobacteria (blue-green algae). These organisms formed structures called stromatolites. These organisms did not become extinct and still exist in both salt and fresh water environments.
Photosynthetic organisms take in what from the atmosphere and combine it with water and energy from the sun to form sugar?
Carbon Dioxide
Where are green algae or other photosynthetic organisms likely to thrive in the ocean?
sunny water that is rich in nutrients.
What are some nutrients used by photosynthetic organisms?
Photosynthetic organisms basically just use water, carbon dioxide, and sunlight to make their own food, hence the name photosynthetic, photo meaning light and synthetic meaning the forming or building of more complex substances or compounds from elements or simplier compounds.
Why can't photosynthetic organisms grow in the deep-water zone of a lake?
They can't grow their because no sunlight reaches.
Why do scientists think that the first organisms did not need oxygen to survive?
Breathable oxygen, or O2, did not exist in large quantities in the atmosphere until after the evolution of photosynthetic organisms. Hence, early organisms had to have an anaerobic metabolism, or one that did not require oxygen. However, compounds containing oxygen, such as water, have always been necessary to organisms.
