Answer:
In the question it is given that the milkweed with clothianidin above the 1ppb concentration will result in less successful hatching of monarch butterfly eggs. Along with the data from the experiments, the exposure of clothianidin on the monarch habitats will lead to a decrease in the population of the monarch butterfly initially. Then in later generations if any mutation occurs and a resistant butterfly is developed then the population of the monarch butterfly will recover. But without this mutation the population size will be reduced and the size and weight of the butterfly will also get reduced.

Graduating from high school this year makes me feel a bit sad. Biology was such a fun but crazy class.
Enough of my sentiments; I'm here to help, :-).
This answer is dependent upon what ecosystem you choose your project over. 
So, abiotic factors are nonliving things in an ecosystem. Biotic factors are living organisms and anything alive. 
For instance, if you choose a pond for your ecosystem then the water, soil, maybe trash would be abiotic factors. Some could argue there is living material within the water and soil but those abiotic factors are not alive. I mean water is not alive but it could be a home to biotic factors like microorganisms such as protozoans and worms. The grass and trees and animals around a pond would be biotic factors. 
Hope you get the idea. if there's any questions then leave a comment and I'll help. Good luck!
        
                    
             
        
        
        
Answer:
from the splitting of water molecule.
Explanation:
The splitting of water molecules  by sunlight is called Photolysis. This is the first reaction in photosynthesis; which occurs by catalysis  of enzymes of Photo system 11.
It involves the splitting of water molecules into;
hydrogen ion/protons.
Oxygen 
and electron.
<u> Oxygen is  the by product liberated into the atmosphere, for animals to inhale for the process of cellular respiration</u><u>.</u>This is the source of oxygen fro cellular respiration in animals.
the hydrogen ions combined with electrons from photosystem 1 to reduce NADP .The latter is used to reduce C02  to form carbohydrate in light independent reaction
