Answer:
All living organisms need energy to stay alive, but only producers can directly convert energy into food.
Explanation:
The process of photosynthesis is very important because all living organisms need energy to stay alive, but only producers can directly convert energy into food.
Photosynthesis is the process whereby green plants manufacture their food in the presence of carbon dioxide and water.
- They take light energy from the sun and produce food materials.
- The light energy is converted to chemical energy which are stored in carbon chains as glucose.
- The chemical energy is then used by other living organisms for their own nourishment.
<u>Answer:</u> The final population of Proteus vulgaris after 6 hours is 
<u>Explanation:</u>
We are given:
Proteus vulgaris divides and doubles every 28 minutes
Total time given = 6 hours = 360 min (Conversion factor: 1 hr = 60 min)
Number of times Proteus vulgaris doubles in 6 hours = 
Calculating the number of bacteria after 6 hours under ideal conditions:
We are given:
Initial population = 500 cells
Number of times it doubles = 12.857 times
Final Proteus vulgaris population = 
Hence, the final population of Proteus vulgaris after 6 hours is

Answer: The food chain
Explanation: It is important to have a large number of producers and herbivores in an ecosystem because of the food chain. Without producers the herbivores would have no food. and without the herbivors the carnivores would have no food.
