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

The ability to produce organic compound in unit time is

  1. Leaching

  2. Productivity

  3. Poaching

  4. Conductivity
Reveal answer Fill a bubble to check yourself
B Correct answer
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 

  1. Leaching

  2. Humifiacation

  3. Catabolism

  4. Mineralization

C Correct answer
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'.

During the process of decomposition in which stage complex organic matter convert into inorganic ions and salts by fungi?

  1. Mineralization

  2. Catabolism

  3. Fragmentation

  4. All of the above

A Correct answer
Explanation

Mineralization is the final stage of decomposition where fungi and bacteria convert complex organic matter into inorganic ions and salts.

In which treatment, microorganism decompose fine organic matter?

  1. Preliminary Treatment

  2. Biological Treatment

  3. Secondary Treatment

  4. Tertiary Treatment

B Correct answer
Explanation

Biological treatment processes in wastewater management utilize microorganisms to break down organic matter. This is the core mechanism for removing dissolved and fine organic pollutants.

End product of 'aerobic' decomposition are:

  1. Unstable

  2. stable

  3. reactive

  4. Non Combustible
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Aerobic decomposition results in stable end products like carbon dioxide, water, and nitrates, which are not prone to further rapid decay. Unstable products are typically associated with incomplete or anaerobic processes.
