Answer:
Answer is true.
Explanation:
A systemic circulation involves the supply of functional blood which is known as the oxygenated blood to cells or body tissues, and subsequently  picks up carbon [iv] oxide and other waste products.
The erythrocytes are the red blood cells which when mixed with oxygen become bright red in color.
Note that, systemic tissues are where the oxygen from the heart are being released and the waste products are absorbed. 
 
        
             
        
        
        
Answer;
The two processes used by producers to obtain energy are photosynthesis and chemosynthesis.
Explanation; 
Producers are those organisms that can make their own energy in an ecosystem using biochemical processes. These biochemical processes are photosynthesis and chemosynthesis.
Photosynthesis involves use of energy from the sunlight together with water and oxygen to make simple sugars. The process converts solar energy to chemical energy (simple sugars). 
Chemosynthesis involves use of chemicals as the energy source, rather than sunlight , to make simple sugars such as glucose.  
Glucose from both processes is then used for respiration to generate energy or stored in form of starch.
