Answer:
b. photosynthesis in which water photolysis produces H , e , and O2 is the correct answer.
Explanation:
- Cyanobacteria is the oxygenic microbes that produce oxygen by a process called photosynthesis.
- Photolysis is the process by which water molecules split into oxygen and hydrogen during the light reaction of the photosynthesis process.
- Cyanobacteria produce their food by photosynthesis.
- Cyanobacteria has chlorophyll that converts carbon dioxide to sugar by carbon fixation.
- Cyanobacteria perform photosynthesis by using carbon dioxide, sunlight, and water to produce oxygen and carbohydrates.
- Thus cyanobacteria utilize the energy from light to split the water molecule and produces H, e , and O2.
<h2>Answer: Atoll</h2>
An atoll is an oceanic coral island, usually in the shape of a circular ring, which may be completely or partially closed. It is also called by this term to the set of several small islands that are part of a coral reef, with an interior lagoon that generally communicates with the sea.
Atolls are formed when a coral reef grows around an oceanic volcanic island, as the island sinks into the ocean and disappears underwater, the growth of the coral increases until reaching the sea level, where the action of the wind and the waves erode it and transform it into sand.
It should be noted that this process can take millions of years.
In this sense, the Maldives, an island country located in the Indian Ocean (southwest of Sri Lanka and a few kilometers from India), has these characteristics.
Its territory is organized in 26 atolls and as a country it is constituted by some 1200 islands.
