If the number of photosynthetic organisms on the earth decreased drastically, which would happen as a result? less water would be available on the earth’s surface. less solar energy would reach the earth’s atmosphere. more oxygen gas would be found in the atmosphere. more carbon dioxide gas would be found in the atmosphere

If the number of photosynthetic organisms on the earth decreased, then the result is that more carbon dioxide gas would be found in the atmosphere.

Photoautotrophs are also called Photosynthetic organisms; they get energy directly from the sunlight and use the energy captured to produce organic compounds in a process known as photosynthesis.

During the process of photosynthesis, the photosynthetic organisms used the inorganic compound of water, carbon dioxide, and sunlight to produce water, glucose, and oxygen.

Further Explanation

Some organisms can capture energy from the sun and in turn, used it to produce organic compounds in a process called photosynthesis. Photosynthesis is very important to life as it gives energy to both the consumers and producers.

Examples of photosynthetic organisms include:

Bacteria (such as Anoxygenic Photosynthetic Bacteria) EuglenaPlants Algae (such as green algae, diatoms, etc)

In photosynthesis, light energy is converted to chemical energy and the energy is stored as glucose. The Inorganic compounds are utilized by photosynthetic organisms to produce water, glucose, and oxygen.

Photosynthetic organisms also use carbon to produce organic molecules and the oxygen, which is produced as a bi-product is used for cellular respiration by both plants and animals.

Many of the organisms, directly or indirectly depend on photosynthesis for nourishment

Photosynthesis
uses carbon dioxide in it's process.Which mean if there are less photosynthetic organisms. There will be more carbon dioxide because the process of photosynthesis will occur less.

The answer is    d.  central highlands

Lol why dont you actually do the work instead of have people do it for you. jk i do it too lol
