Answer:
Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.
Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
 
        
                    
             
        
        
        
I think the answer is B
Beacuse It follows the successful completion of S phase, during which the cell's DNA is replicated. Mitosis is a part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus.
        
             
        
        
        
Answer:
Hypochlorhydria is a condition in which the quantity of stomach acids is reduced. When severe forms of hypochlorhydria arise, then it leads to a condition termed as Achlorhydria. The stomach stops producing hydrochloric acid at all in such a condition.
The effects of Achlorhydria would be devastating on the body. It will 
-  weaken or entirely stop the digestive process.
 -  impair the gastrointestinal system.
 - stop the proper digestion of proteins.
 - cause gastrointestinal infections to occur which would entirely damage the digestive system.
 - lead to iron deficiency
