Answer:
In the Northern Hemisphere, ecosystems wake up in the spring, taking in carbon dioxide and exhaling oxygen as they sprout leaves — and a fleet of Earth-observing satellites tracks the spread of the newly green vegetation.
Meanwhile, in the oceans, microscopic plants drift through the sunlit surface waters and bloom into billions of carbon dioxide-absorbing organisms — and light-detecting instruments on satellites map the swirls of their color.
Satellites have measured the Arctic getting greener, as shrubs expand their range and thrive in warmer temperatures. Observations from space help determine agricultural production globally, and are used in famine early warning detection. As ocean waters warm, satellites have detected a shift in phytoplankton populations across the planet's five great ocean basins — the expansion of "biological deserts" where little life thrives. And as concentrations of carbon dioxide in the atmosphere continue to rise and warm the climate, NASA's global understanding of plant life will play a critical role in monitoring carbon as it moves through the Earth system.
Explanation:
It would decrease as their prime food source would be taken away. This would result in a decline in population as the birds wouldn’t have sufficient food.
Hope that helps. :)
Answer:
Chemical digestion actually starts in the mouth when our saliva mixes in with the food. So, A. wouldn't really be correct. It's not the molars that are doing the chewing, but rather your jaw muscels. I don't even know what pepsin is... <u>C. would probably be your best bet because it's your saliva that breaks down your food and helps you chew it.</u> And D. your tongue just helps to move the food around...
Explanation:
Hope this helps you!!!
Holding your breath while ascending can lead to all of the above options.
Surfacing excessively fast or holding the breathing while swimming to the surface can make the air in the lungs expand which is known as pneumonic barotrauma. This might break lung tissue, which can prompt gas bubbles to be delivered into the blood vessel dissemination (arterial gas embolism).
The air in the lungs becomes risky when an individual ascends. On the off chance that somebody holds their breath while rising to the surface, the lungs and the air inside them extend as the water pressure decreases. Since that air has no place to escape, it continues to expand against the walls of the lungs, no matter what the organ's capacity.
