Question

Which life process is classified as autotrophic in some organisms and heterotrophic in others?
a) Hormonal regulation
b) Nutrition
c)Anaerobic respiration
d)Transport

Answer 1

Autotrophic is the mode of nutrition in which the plant makes its own food and does not depend on others for the food and nutrition. The heterotrophic mode of nutrition is the mode of nutrition in which the plants derive their food from the other source rather than making it by themselves.

Complete answer:
The life process in which the autotrophic and heterotrophic are involved is nutrition. They are the mode of nutrition which are adapted by the organisms. The plants are mostly autotrophic in nature whereas the other organism is regarded as heterotrophic in nature. The organism is considered to be heterotrophic because they obtain their nutrition and food source from either some plant variety or by killing and eating other animals. These organisms do not have the capability to make their own food by themselves.

Additional Information: The process of respiration can be divided into aerobic respiration and anaerobic respiration. The respiratory process in which there is the involvement of the oxygen or presence of oxygen is required is known as the aerobic respiration. The process of respiration which is carried out in the absence of the oxygen is known as anaerobic respiration. The transportation or the movement of the body of an organism causes its locomotion. Locomotion is obtained with the help of muscles and bones present in the body of the organism. The hormones are the molecules which are released when they receive some signals from the body tissues and organs.
So, the correct answer is ‘nutrition’.

Note: The heterotrophic mode of nutrition can also be divided into consumers, detritivores, and saprotrophs. The consumer organism usually feeds on the organic matter present. The detritivores feed on the non-organic matter and the saprotrophs feed on the non-living organic matter by secreting certain digestive enzymes.
