Biodiversity is the variety and variability of life on Earth. Many areas within the tropical zones are considered biodiversity hotspots and are home to the world's most rare and endangered species.
Yes, an organism does adapts itself to the new environment in order to increase its fitness. Each organism has its unique ecosystem in which it lives. This is where all of its necessary needs of water, food and reproduction are met.
In order to survive, an organism has to adapt to its habitat which helps to compete and survive in that ecosystem.This modification or adaptation helps the organism to survive and be fit for its habitat.

Answer:
B) Glucose molecules are joined in long, branched chains to make glycogen that allows for long term energy storage in animals.
Explanation:
Starch:
Starch is a complex polysaccharide made up of glucose molecules bonded via glycosidic linkage. Starch is primarily of two forms:
- A linear polymer of glucose molecules bonded together by α 1,4 glycosidic linkage known as amylose.
- A highly branched, complex polymer of glucose bonded together by α-1,4 and α-1,6 glycosidic linkages known as amylopectin. The α-1,6 linkage is responsible for branching in amylopectin.
Unlike starch, cellulose is a polymer consisting of linear chains of glucose units. Cellulose is indigestible for humans. It is excreted as dietary fiber.
Glycogen:
Glycogen is the primary form of glucose storage in animals, fungi and bacteria. Glycogen is also a complex, branched polymer of glucose units. Glycogen mainly contains amylopectin i.e a highly branched form of glucose polymer that contains α-1,4 and α-1,6 glycosidic linkages.
Chitin:
Chitin is a long chain polymer of modified form of glucose i.e. N-acetylglucosamine which is a nitrogen containing derivative of glucose. N-acetylglucosamine monomers are linked together through glycosidic bonds.
