Hi I am having trouble with a few questions in my biology.

1. Is It True That Carbon can link itself and other elements to form very large molecular structures?

2. A. How would the composition of earths atmosphere change if green plants and other autotrophs disappeared? Explane in tems of photosynthesis.

b. How would animal life be affected by this atmosphere change? Explane in knowlege of Cellular respiration.  

Answer
HI Aiannyl
1. This is true
2 A The heterotrophs would deplete the atmosphere of Oxygen and the Earth would return to the way it was before there were green plants.  Photosynthesis would cease
3. All animals would die.  No glucose would be made and cellular respiration needs glucose.
