Answer:
Energy supply
Explanation:
Nutrition, which is the ability to obtain food, is one of the characteristics of living organisms. However, the food ingested by organisms serve series of purposes in their system. These functions include maintaining biomass (total weight), and waste production as mentioned in the question.
In addition to this, one important role food ingestion plays in living organism is the SUPPLY OF ENERGY. Food ingested is broken down into smaller units, which is then used by the cells to synthesize energy in form of ATP. This process in living organisms is called RESPIRATION.
The energy (ATP) is used to power various cellular functions undergone by the organism.
Apart from maintaining biomass and waste production, food ingested by organism serve as Energy supply.
Nutrition can be regarded as biochemical as well as a physiological process whereby organism utilize food to support its life.
- Nutrition involves process such as;
ingestion
absorption
assimilation
biosynthesis
catabolism
excretion.
- What the question actually stressed on is ingestion, ingestion plays a vital roles in system of organism these are maintaining biomass as well as waste production.
- ingestion helps in supplying of energy to the living organism, once food is invested, then it will be broken to down into smaller units, this units are utilized by cells in synthesizing of energy in form of ATP in a process called respiration.
Therefore, food ingested by organism can serve as source of energy to them
