Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.
In order for energy to be able to be created, ATP(adenosine triphosphate) needs to form in either photosynthesis or krebs cycle from ADP + P(from NADPH). When ATP is available, huge amounts of energy are released when needed by slicing one P atom from ATP So that it can again become ADP and undergo lots of processes to become ATP again. So energy is added from tearing of Phosphate Atom due to tearing of phosphoanhydride bonds. This is possible because of process known as hydrolysis, when ATP is in equilibrium with water and some electrons. And the process of ADP becoming ATP is recharging and occurs in mitochondria.
The processes are hydrolysis and rechargeation, but most important process is Krebs Cycle, where all of this happens.
They absorb food from their environment and release ammonia into their environment through their body surface because their body is very flat, due to the lack of coelom

Answer: About 500 individuals have died in the last 5years
Explanation:
Mortality rate is 1.5 per 1000 persons
Total population is 150,000
Therefore 3/2*1000=1500
150,000/1500=100 persons
In five years,at same rate=5*100=500persons
