Answer: The producers refers to green plants that carry out the process of photosynthesis in order to produce food for themselves and others. The principal function of producers is to manufacture food for themselves and all other living organisms.
The consumers refers to those living organisms that can not produce their own food and have to depend on the food produce by others. Consumers can be categorized into primary, secondary and tertiary consumers depending on where they are located on the trophic levels. They can also be classified as herbivores, carnivores and omnivores depending on the type of food they eat. The major function of consumers is transference of energy. Consumers transfer the energy they obtain from the food they eat to those animals that feed on them. 
The decomposers are those micro organisms that are majorly found in soils.The principal function of decomposers is to break down dead organic matters so that they can be absorbed by the roots of plants. The broken down organic substances serve as nutrients, which the plants used to grow and develop. 
These three types of organisms work together in the ecosystem to maintain the balance of the ecosystem.  
 
        
             
        
        
        
Platelets start a clotting reaction that intimately produces a clot composed of fibrin, is a form of Fibrinogen
Explanation:
Fibrinogen is blood plasma Protein which is converted into those protein fibrins in the clotting process. After removal of clot the fibrinogen free fluid is obtained and this fluid is known as blood serum. It shows strong flow birefringence. It is highly viscous. 
By half saturation process and using the sodium chloride fibrinogen can be participated from the blood plasma. Through thrombin process clotting is initiated. With the help of electron micrographs, its molecules look like a rod whose length is 47.5 nanometre.

Answer:
Iron deficiency anemia is a common type of anemia — a condition in which blood lacks adequate healthy red blood cells. Red blood cells carry oxygen to the body's tissues. As the name implies, iron deficiency anemia is due to insufficient iron.
The most common cause of anemia is low levels of iron in the body. This type of anemia is called iron-deficiency anemia. Your body needs a certain amount of iron to make hemoglobin, the substance that moves oxygen throughout your body
I think its anemia
