Answer:
C. growth of plants after a forest is destroyed by fire
Explanation:
When the ecological succession occurs on the land or region which was never inhabited by plants previously, the process is called primary succession. On the other hand, secondary succession occurs on land where the existing vegetation was destroyed by some disturbances. Secondary succession is a fast process compared to the primary succession as the soil is already present to support the growth of plants.
Among the given examples, the growth of plants after the vegetation of forest was destroyed by fire represents the process of secondary succession. Growth of vegetation on bare rocks, in the cracks in the concrete surface, or after the melting of glaciers represents the process of primary succession.
Answer:
a. retained in the pyruvate
Explanation:
Glycolysis is a cytoplasmic pathway that converts glucose into two pyruvate, releasing a modest amount of energy captured in two substrate-level phosphorylations and one oxidation reaction.
Following are the important enzymes in it :
- Hexokinase
- Phosphofructokinase
- Pyruvate kinase
Aerobic glycolysis yields 2ATP/glucose plus 2NADH/glucose but most of the energy is retained in pyruvate which is then converted into Acetyl-CoA and enters the kreb's cycle.
Answer: Option A.
Electrons,carbon and energy.
Explanation:
Chemorganoheterotrophs are organisms that uses organic substrates to produce carbon needed for their growth and development. They derive their energy from oxidation and reduction of organic substances. The use the reduced carbon produced by autrotophs as as source of electrons, carbon and energy. Example is fungi that uses carbon as electron donor and source for carbon and energy.
