Biggest Animal in the World

Elephant - Option c

Explanation:

Size:
- Elephants are the biggest land animals on Earth, with African elephants being the largest of the species. They can grow up to 13 feet in height and weigh up to 14,000 pounds, making them massive creatures.

Physical Characteristics:
- Elephants have a unique trunk that they use for breathing, smelling, touching, grasping objects, and producing sound. They also have long tusks, which are actually elongated incisor teeth, that can be used for defense, digging for water, and gathering food.

Habitat:
- Elephants are found in various habitats such as forests, savannas, and grasslands in Africa and Asia. They are known for their social behavior, living in herds led by a matriarch.

Diet:
- Elephants are herbivores and primarily feed on grasses, leaves, bark, and fruits. They have to consume large amounts of food daily to sustain their massive size.

Importance:
- Elephants play a crucial role in maintaining the ecosystems they inhabit. They are known as keystone species as they shape their environment through feeding habits and seed dispersal.

Conservation:
- Due to habitat loss, poaching, and human-elephant conflicts, elephant populations are declining rapidly. Conservation efforts are being made to protect these magnificent animals and ensure their survival in the wild.

Similar UPSC Doubts

It has long been known that the rate of oxidative metabolism (the process that uses oxygen to convert food into energy) in any animal has a profound effect on its living patterns. The high metabolic rate of small animals, for example, gives them sustained power and activity per unit of weight, but at the cost of requiring constant consumption of food and water. Very large animals, with their relatively low metabolic rates, can survive well on a sporadic food supply, but can generate little metabolic energy per gram of body weight. If only oxidative metabolic rate is considered, therefore, one might assume that smaller, more active, animals could prey on larger ones, at least if they attacked in groups. Perhaps they could if it were not for anaerobic glycolysis, the great equalizer. Anaerobic glycolysis is a process in which energy is produced, without oxygen, through the breakdown of muscle glycogen into lactic acid and adenosine triphosphate (ATP), the energy provider. The amount of energy that can be produced anaerobically is a function of the amount of glycogen present—in all vertebrates about 0.5 percent of their muscle’s weight. Thus, the anaerobic energy reserves of a vertebrate are proportional to the size of the animal. If, for example, some predators had attacked a 100-ton dinosaur, normally torpid, the dinosaur would have been able to generate almost instantaneously, via anaerobic glycolysis, the energy of 3,000 humans at maximum oxidative metabolic energy production. This explains how many large species have managed to compete with their more active neighbours: the compensation for a low oxidative metabolic rate is glycolysis.Q. The author suggests that, on the basis of energy production, a 100-ton dinosaur would have been markedly vulnerable to which of the following? Repeated attacks by a single smaller, more active adversary Sustained attack by numerous smaller, more active adversaries An attack by an individual adversary of similar size
