What else can I help you with?
What gas is given off by animals at daytime to the atmosphere?
Animals give off a number of gasses during Day and night, most notably Carbon dioxide and methane gas. Oxygen is needed by man and animal.
What is given off by plants which is needed by man and animals?
oxygen
What gas is giving off by animals and man and the gas neededby plants?
Carbon Dioxide
What is given off by plants wich is needed by man and animals?
Oxygen. Plants take in the Carbon Dioxide that man and animals exhale, and give off oxygen.
Why is photosynthesis badly needed by man and animals?
Photosynthesis is where plants get nutrients from the sun. This is important for man and animals because, if the plants couldn't use photosynthesis, they would die off. If all the plants die off, then man and animals couldn't get nutrients fom the plants, therefore making the process of photosynthesis needed by both plants and animals.
What gas does man and animals given off when they exhale?
Carbon dioxide, CO2.
What gas to plants release into the air that animals use to start respiration?
CO2 (carbon dioxide) is exhaled by animals and needed by plants for photosynthesis.
Gas given off by plants that is needed by animals?
The gas given off by plants that is needed by animals is oxygen. Through the process of photosynthesis, plants convert carbon dioxide into oxygen, which animals then breathe in to support their respiration. This exchange of gases between plants and animals is vital for the survival of both organisms.
Why does god create the world and finally man?
Because he needed a caretaker for the world and all the animals on it. Read the Bible. Man needed an Earth to live on. God wouldn't let man die in nothingness on the first day and then create the earth on the sixth.
What do you use greenhouse gases for?
Drinking and keeping our food supply alive is a use for the most common (80%) green house gas. That is water vapor. The second most common greenhouse gas comes from anything that dies and rots, CO2. Man also produces 3 to 6% of this gas. The rest comes from natural sources. The third most common gas is methane, which comes from animals. In this arena man produces much of this gas through the farming of animals. Almost 1% of this gas is made by humans. In total man produces about 0.28% of all green house gas. Much of this amount from items that would produce it even if man were not around.

What problems were associated with colonizing land during the evolution of vertebrates?
1) Animals needed to withstand the effects of gravity. 2) Animals needed to reduce desiccation (the loss of water). 3) Animals needed to have a mode of transportation. 4) Animals needed protection against UV rays. 5) Animals needed to reproduce without water. 6) Animals needed to breathe air. 7) Animals needed to adjust their senses to life out of water.
