Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Mineralization is the specific stage of decomposition where microbial action converts organic nutrients into inorganic forms that plants can absorb.

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

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

  1. Mineralisation

  2. Catabolism

  3. Fragmentation

  4. All of these

A Correct answer
Explanation

Mineralisation is a process in which complex organic matter present in humus is converted into inorganic salts and ions. It is done by the action of saprophytic fungi.

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

Which of the following process helps in nutrient conservation?

  1. Mineralisation

  2. Immobilisation

  3. Leaching

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

Immobilization is the conversion of inorganic compounds to organic compounds by microorganisms or plants, by which it is prevented from being accessible to plants. Immobilization is the opposite of mineralization. Plants utilize minerals in inorganic form. Hence, immobilization helps in nutrient conservation.

So, the correct answer is 'Immobilization'.

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

The decomposed organic matter is called

  1. Callose

  2. Callus

  3. Litter

  4. Humus
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Decomposition is the process of breaking of complex organic matter into simpler inorganic matter. There are five steps of decomposition. These are fragmentation, leaching, catabolism, humification and mineralization. Fragmentation is the process of breaking of detritus into small pieces by detrivores. Leaching is the process of releasing nutrients in the water and seeping into the soil. Catabolism is the process of breaking down of complex molecules into the simpler molecules. Humification is the process of formation of dark colored humus on the soil. The decomposed organic matter is called as humus. Mineralization is the process of degradation of the hummus to release inorganic nutrients.

Thus, the correct answer is 'Humus.'

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

Breakdown of detritus into smaller particles by earthworm is a process called

  1. Humification

  2. Fragmentation

  3. Mineralisation

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

Decomposition is the process of breaking of complex organic matter into simpler inorganic matter. There are five steps of decomposition. These are fragmentation, leaching, catabolism, humification and mineralization. Fragmentation is the process of breaking of detritus into small pieces by earthworm. Leaching is the process of releasing nutrients in the water and seeping into the soil. Catabolism is the process of breaking down of complex molecules into the simpler molecules. Humification is the process of formation of dark colored humus on the soil. MIneralization is the process of degradation of the hummus to release inorganic nutrients.

Thus, the correct answer is 'Fragmentation.'

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

The process of breakdown of detritus by detrivores is

  1. Mineralisation

  2. Fragmentation

  3. Leaching

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

Decomposition is the process of breaking of complex organic matter into simpler inorganic matter. There are five steps of decomposition. These are fragmentation, leaching, catabolism, humification and mineralization. Fragmentation is the process of breaking of detritus into small pieces by detrivores such as earthworm. Leaching is the process of releasing nutrients in the water and seeping into the soil. Catabolism is the process of breaking down of complex molecules into the simpler molecules. Humification is the process of formation of dark colored substance humus on the soil. It undergoes microbial action at a slow rate. Mineralization is the process of degradation of the hummus to release inorganic nutrients.

Thus, the correct answer is 'Fragmentation.'

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

During the process of decomposition, in which stage complex organic matter is converted to inorganic ions and salts by fungi?

  1. Mineralization

  2. Catabolism

  3. Fragmentation

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mineralization in the process of decomposition in which complex organic matter is oxidized into soluble inorganic ions and salts. It increases bioavailability of the nutrients as soluble inorganic form is readily available to plants. The process is carried out by soil microorganisms like bacteria and fungi.

Thus, the correct answer is option A.

The different steps involved in the process of decomposition of detritus are

  1. Fragmentation

  2. Leaching and Catabolism

  3. Humification and mineralization

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Decomposition is the process in which complex organic matter is broken down into inorganic raw materials with the help of decomposer. There are different steps involved in the process of decomposition of detritus like:
(1) Fragmentation: In this, complex organic matter is fragmented into smaller pieces by earthworms.
(2) Leaching: In this, water soluble nutrients penetrates into the soil layers and get locked as unavailable salts.
(3) Catabolism: In this, bacteria and fungi degrade detritus through various enzymes.
(4) Humification: This step results in the formation of a dark-coloured colloidal substance called humus. It is a reservoir of nutrients for plants.
(5) Mineralization: The humus is further degraded by the action of microbes and inorganic nutrients are released into the soil by the process of mineralization.
Thus, the correct answer is 'All of the above.'
