Answer:

The answer is 'B'- There is already soil present.

Explanation:

One of the biggest difference between primary succession and secondary succession is that primary succession occurs where there is zero availability of  soil. In case of secondary succession, an already established community gets hampered due to <em>man made</em> activities or natural disasters like <em>flood, rain</em>, etc.

Since there is soil present in his farmland and vegetation is also available, it is the process of secondary succession.

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:

  1. A linear polymer of glucose molecules bonded together by α 1,4 glycosidic linkage known as amylose.
  2. 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.
