Secretory pathway refers to the channel through which the secretory organelles secrete proteins to the extracellular compartment.
The polypeptide transport in the secretory pathway involved the transportation of proteins from the ribosomes to the endoplasmic reticulum and then to the golgi bodies and finally to the plasma membrane.
        
             
        
        
        
<span>A scientific theory is NOT a wild guess. It must be consistent with known experimental results and it must have predictive power. As new knowledge is gained, theories are refined to better explain the data. A law is a mathematical relationship that is consistently found to be true.</span>
 
        
        
        
Answer:
The size is reduced as 80-95% of the available energy at one trophic level is not transferred to the next
Explanation:
There is loss of energy as it is transferred between trophic levels. The decrease in energy as it moves up the pyramid is due to energy loss as metabolic heat when one organism is consumed by another from the next level as it moves up the trophic levels.
