Answer:
photosynthesis
Explanation:
the formula for photosynthesis is 
6CO2 + 6H2O + Light energy → C6H12O6 (sugar) + 6O2 +ATP

I think C) availability of water is your best answer because alot of organisms count on water as a major resource because they need it to survive so a lack or a gain in the amount of water will majorly effect an ecosystem.
 
        
                    
             
        
        
        
Answer:
<em>1. They effect crop productivity</em>
As weeds start to grow in the area where the crops were destined to grow, the production of the crops gets lowered.
<em>2. They deplete the crops from nutrition</em>
The weeds will compete with the crop plants for resources such as minerals from the soil.
<em>3. They will deplete water resources</em>
The weeds will compete with the crop plants for water.
<em>4. Sun-light will be depleted</em>
The weeds will complete with the crop plants for sun light.
<em>5. The crop quality will be affected</em>
As the crop plants will be in competition with the weeds, hence their quality will be affected.
6.  <em>They can reduce the biodiversity of crop plants.</em>
 
        
             
        
        
        
The fourth way chemicals can enter the body is by injection. It can happen when a sharp device (like a needle) punctures the skin and injects a chemical (or virus) directly into the bloodstream, however it is unusual in most industries.
<h3>What in biology is the blood stream?</h3>
The phrase "bloodstream" refers to the flow of blood within an organism's body. In humans, the circulatory system, which is made up of a complicated network of arteries and veins, is where blood travels.
<h3>Where does the bloodstream reside?</h3>
The blood is gathered in veins and moves to the right atrium and right ventricle while being depleted of oxygen. The pulmonary circulation starts here: Low-oxygen blood is pumped from the right ventricle into the pulmonary artery, which divides into progressively smaller arteries and capillaries.
