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
Explanation:
a) Mineralization- Mineralization is the decomposition (i.e. oxidation) of the chemical compounds in organic matter by which the nutrients in those compounds are released in soluble inorganic forms. It is done by the action of microorganism specially saprophytic fungi. b) Catabolism - The breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy: destructive metabolism. c) Fragmentation- Fragmentation is a method of Asexual Reproduction, where the body of the organism breaks into smaller pieces, caused fragments and each segment grows into an adult individual. Examples. Hydra, spirogyra etc.

Assertion (A) : Soil is a major factor for establishment of a biotic community with diverse organisms and it takes several hundred to thousand years to produce fertile soil on bare rock. Reason (R) : Lichens secrete acids to dissolve rock for soil formation. The correct answer is :
1 Both (A) and (R) are true, (R) is the correct explanation of (A).
2 Both (A) and (R) are true but (R) is not the correct explanation of $(A)$.
3 (A) is true but (R) is false.
4 (A) is false but (R) is true.
Explanation:
This partnership allows lichens to colonize harsh environments such as the alpine areas of grand teton national park. Acids secreted by lichens dissolve the surface of the substrate they grow on. Since lichens are among the first plants to grow on bare rock. they play a role in soil formation by slowly etching the rock surface.

Peacock eats a snake and snake eats frog and frog eats insect while insect eats green plant, then position of peacock is
1 Primary producer
2 Secondary producer
3 Decomposer
4 Top at the apex of food pyramid
Explanation:
Top at the apex of food pyramid Green Plant-Insect (Grasshopper) $\rightarrow$ frog $\rightarrow$ snake peacock. - In the food chain the green plant is the primary producer by trapping energy from sunlight. The insect (Grasshopper) is the primary consumers, because they directly consume the green plant. - Frog is the secondary consumer, because it eats the grasshopper. - The snake, a secondary carnivore eats the frog. - The peacock is the tertiary carnivore because it eats the secondary carnivore, the snake. Primary producer - Primary producer in a terrestrial ecosystem live in the organic matter. Since they are not mobile, they live and grow where there nutrient to sustain them. Secondary producer - A secondary producer is a herbivore. An animal that eats plant matter and in turn is food for a predator. Decomposer - Decomposers are organisms that break down dead or decaying organisms. They carry out decomposition a process possible by only certain kingdom such as fungi.

Identify the incorrect statement regarding the flow of energy between various components of the food chain.
1 Each trophic level loses some energy as heat to the environment.
2 The amount of energy available at each trophic level is $10 \%$ of previous trophic level.
3 Energy flow is unidirectional.
4 Green plants capture about $10 \%$ of the solar energy that falls on leaves.
Explanation:
The flow of energy in a food chain is unidirectional, green plants capture about $100 \%$ of the solar energy that falls on leaves. Each trophic level losses some energy as heat to the environment. The amount of energy available at each trophic level is $10 \%$ of previous trpohic level.
