The way in which carbon is reused through the ecosystem is known as

botany ecological adaptations, succession and ecological services ecosystem services ecosystems ecosystem

  1. Energy recycling

  2. The energy pyramid

  3. The biotic/abiotic cycle

  4. The carbon cycle

Show answer
Correct Option: D
Explanation:

  • The carbon cycle is the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
  • Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone.
So, the correct answer is 'The carbon cycle'.

The process of photosynthesis and respiration cause the cycling of ........... through the environment.

  1. Carbon

  2. Water

  3. Nitrogen

  4. Hydrogen

Show answer
Correct Option: A
Explanation:

The plants can fix carbon dioxide from the atmosphere which is taken in through stomata. The carbon dioxide is converted in the presence of light and chlorophyll pigments to synthesize carbon containing organic compounds such as sugar, fats and proteins. This creates the plant biomass which when eaten by other organisms recycles the carbon from on level to other. Finally the carbon enters the geosphere and then the atmosphere. The oxygen which is formed during photosynthesis is liberated in the atmosphere and used for cellular respiration. The oxygen is used to break down the molecules and release the carbon dioxide. The carbon gets recycled in the environment from plants to animals and then again enters the environment. 

Thus, the correct answer is option A. 

Parachute type of mechanism of seed dispersal is found in

botany ecological adaptations, succession and ecological services ecosystem services ecosystems ecosystem

  1. Pea/ Leguminosae

  2. Mustard/ Cruciferae

  3. Cotton/ Malvaceae

  4. Taraxacum/ Compositae

Show answer
Correct Option: D
Explanation:
  • Parachute mechanism of fruit and seed dispersal is due to a structure called pappus. 
  • Pappus is the Calyx. Pappus or fruit and seed dispersal mechanism is a modification process and this process is known as Calyx. Calyxes are the protective shield of the flower and they can protect the reproduction system of the flower. They help the flower to produce seeds. 
  • Parachute mechanism is characteristic of family Compositae.
  • Hence Parachute type of mechanism of seed dispersal is found in Taraxacum/ Compositae.
  • So, the correct answer is 'Taraxacum/ Compositae'.

An easily disturbed ecosystem which can recover after sometime after the stoppage of damaging factor, is of

botany ecological adaptations, succession and ecological services ecosystem services ecosystems ecosystem

  1. Low stability and high resilience

  2. High stability and high resilience

  3. Low stability and low resilience

  4. High stability and low resilience

Show answer
Correct Option: A
Explanation:

Answer is option A i.e. "Low stability and high resilience"
Stability is the power of a system to be in their state against unfavorable factor. Resilience is the capability of regaining its original shape or position after being deformed. An ecosystem which can be easily damaged but can recover after sometime when it 's damaging effect stops will be having low stability and high resilience. Hence, it has low stability and high resilience.

Heavy rainfall during summer produces

botany ecological adaptations, succession and ecological services ecosystem services ecosystems ecosystem

  1. Desert

  2. Grassland

  3. Forest

  4. Wetland

Show answer
Correct Option: B
Explanation:

During summer the land becomes dry and rainfall induces formation of grass and hence heavy rainfall during summer produces grasslands.

So, the correct answer is 'Grassland'
