Questions Related to producers, consumers and decomposers

The ability to produce organic compound in unit time is

zoology ecosystems decomposition in ecosystem ecosystem productivity and decomposition producers, consumers and decomposers

  1. Leaching

  2. Productivity

  3. Poaching

  4. Conductivity

Show answer
Correct Option: B
Explanation:
  • Productivity is the rate of production of new biomass by an individual, population. 
  • Productivity is a key source of economic growth and competitiveness.
  •  A country's ability to improve its standard of living depends almost entirely on its ability to raise its output per worker, i.e., producing more goods and services for a given number of hours of work.
  •  Hence, The ability to produce the organic compound in unit time is Productivity.
  • So, the correct answer is 'Productivity'.

If breakdown of the detritus by detritivores is called fragmentation, then degradation of the detritus into simple inorganic substances,by bacterial and fungal enzymes is known as 

zoology ecosystems decomposition in ecosystem ecosystem productivity and decomposition producers, consumers and decomposers

  1. Leaching

  2. Humifiacation

  3. Catabolism

  4. Mineralization

Show answer
Correct Option: C
Explanation:

If the breakdown of the detritus by detrivores is called fragmentation, then the degradation of the detritus into simple inorganic substances, by bacterial and fungal enzymes is known as catabolism.

Leaching is the process by which the water-insoluble inorganic nutrients go down into soil horizon and get precipitated as unavailable salts.
Humification is the process of accumulation of a dark-colored amorphous substance called humus.
Mineralization is the process in which humus is further degraded by some microbes and release of inorganic nutrients occur.
So, the correct answer is 'Catabolism'.
