Trees "breath" in carbon dioxide and exhale oxygen during the morning, so they clean all the carbon dioxide that we breath out daily
But I have to warm you, tree does the opposite at night, if you sleep in a room with a lot of plants, you could be in danger because tree inhale oxygen and exhale carbon dioxide, they soon will consume all your oxygen XD

The increase in insulin level following an increase in glucose level in the blood can best be explained by A FEED BACK MECHANISM THAT REGULATE THE BLOOD GLUCOSE LEVEL.
Insulin is an hormone that is secreted by the pancreas and it functions by regulating the amount of glucose that is found in the blood. When the level of glucose in the blood is higher than normal, insulin interfere by converting the excess glucose into glycogen. The glycogen is stored in the liver and in the skeletal muscles and they will only be converted back into glucose, if the level of glucose in the blood is lower than normal.
No. Below 1000m the sunlight could not reach therefore plant like organism would not be able to grow there. However if the organism does not need sunlight then it might have a small chance of survival. Of course there also is the water pressure that can also pose a problem. So I say No.
