Answer:
1. Global warming is the change in the climate of the earth causing it to heat up whereas the greenhouse effect is a naturally occurring phenomena, constantly occurring due to the atmosphere and sunlight.
2. Carbon dioxide absorbs heat radiating from the Earth's surface and re-release it in all directions—including back toward Earth's surface.
3. Decomposition, ocean release and respiration.
 
        
             
        
        
        
The answer is C.
It is not true that CO2 is released during photosynthesis, rather its the opposite. Carbon dioxide is a raw material for the production of  starches and cellulose through photosynthesis. Atmospheric carbon dioxide is captured during the light dependent reactions of photosynthesis then used for the production of starch, glucose and cellulose in the light independent reactions (Calvin cycle)  of photosynthesis.
In aerobic cellular respiration, oxygen rather than Carbon dioxide is a requirement because it is needed as the terminal electron acceptor in the production of ATP.
 
        
                    
             
        
        
        
I am going to assume you meant "chloroplasts" instead of "Hloroplasts"
Your answer will be plant cells
Chloroplasts makes the energy for the plant by conducting photosynthesis, therefore, they are only found in plant cells.
