NEET BIOLOGY

Detailed explanation-1: -If all diatoms were to suddenly go extinct, what would happen to the earth’s atmosphere? Because diatoms perform a large amount of the earth’s photosynthesis which produces oxygen, the atmosphere would dwindle away. An organism forms a hard shell around itself in response to life-threatening conditions.

Detailed explanation-2: -Other types of phytoplankton would replace them, but these are less effective in removing carbon, or even add carbon to the atmosphere. Fewer diatoms would thus reduce the ability of the ocean to remove carbon dioxide from the earth’s atmosphere.

Detailed explanation-3: -Diatoms in the world’s oceans exhale more oxygen than all the world’s rainforests. These tiny drifting algae generate about 20 percent of the oxygen produced on Earth each year, and invisibly recycle gases enveloping our planet.

Detailed explanation-4: -Thus, a decrease in the population of diatoms has the potential to bring about climate change by causing an increase in the amount of unfixed carbon and decrease in the levels of oxygen, required for respiration of most living organisms.

Detailed explanation-5: -If the ozone layer in the atmosphere completely disappears, then the harmful ultraviolet radiations from the sun would enter the earth’s surface and cause skin cancer and many other ailments in humans and animals, and may also damage plants. Q.
