One of the main disadvantages of being an endotherm is: can only live in clod regions of the world need a large supply of food must hibernate during the winter metabolic rate is lower than in ectotherms cannot live in aquatic environments Which process is NOT part of food processing in animals? Absorption digestion ingestion elimination coagulation

Solution

Ans. 1. The animals capable of thermoregulation, i.e. maintenance of body temperature at a relatively constant level, are called endotherms.

# One of the main disadvantage of being an endotherm is B. need a large food supply. Because endotherms spend a large amount of energy for thermoregulation, they need to obtain greater food intake compared to those animals that do not thermoregulate their body temperature.

Option A: Incorrect: Endotherms can live in any temperature condition because they can regulate their body temperature.

Option C: Incorrect: True endotherms do not need to hibernate for avoiding cold. They can keep their body warm through thermoregulation.

Option D. Incorrect: Because endotherms need to regulate their body temperature besides normal metabolic processes, they perform additional metabolic pathways involved in thermoregulation. So, they have higher metabolic rates.

Option E: Incorrect: Many aquatic mammals, like whales, are endotherm.

Ans. 2. Correct option: Coagulation.

Food processing includes ingestion (food intake), digestion (breakdown of food into smaller particles), absorption (uptake of nutrients by blood/lymph) and elimination (excretion of undigested material).

Coagulation is the process of clumping together of soluble particles in a solution into large, insoluble particles. For example, blood coagulates from solid into gel form.

Coagulation is an undesirable process for digestion because aggregates of food particles increases surface area of the food particles and minimizes enzymatic activity on it. Moreover, coagulation also reduces the efficiency of nutrient absorption.
