The constant turnover of body tissues requires the <u>chemical energy </u>supplied by carbohydrates, proteins, and lipids.
<h3> What is Chemical energy?</h3>
- The bonds of chemical molecules contain energy. 
- Exothermic reactions are those in which chemical energy is released during the reaction, frequently in the form of heat. 
- Some of the heat energy needed for a reaction to continue can be stored as chemical energy in newly created bonds. 
- The body transforms the chemical energy in food into heat and mechanical energy. 
- At a power plant, coal's chemical energy is transformed into electrical energy. Through the process of electrolysis, the chemical energy in a battery can also generate electricity.

Answer:
C. Population shrinks; 15 birds in  the end
Explanation:
Let us understand some of the given terms; 
   immigration is a form of migration in which organisms comes into a territory. 
   emigration is a form of migration in which organisms leaves a place
  population is a group of organisms of the same species
Given: 
Population  = 21 birds
Immigrant = 3 birds
Emigrants  = 9 birds
  Population change = total number of birds + immigrant  - emigrants
                                    = 21 + 3 - 9 
                                      = 15 birds
The population will shrink giving 15 birds in the end
