Question Discussion & Solution

Food chain: 

• A food chain shows the feeding relationship between different organisms in a particular environment and/or habitat.
• A food chain shows how energy is passed from the sun to producers, from producers to consumers, and from consumers to decomposes such as fungi.
• They also show how animals depend on other organisms for food.
• A simplified food web illustrating a three-trophic food chain (producers-herbivores-carnivores) linked to decomposers.

Key Points

Food Web: 

• A food web is similar to a food chain, but the food web is significantly larger.
• Occasionally, a single organism is eaten by a large number of predators, or it consumes a number of other species.
• As a result, several trophic levels become intertwined, and the food chain fails to accurately depict the flow of resources.
• The food chains are very simple and hence, do not exist in reality, 
• Rather, an interconnection of many food chains is seen in nature or in our ecosystem that forms a food web.
• The energy flow is multidirectional.
• In a food web, one organism takes place at different trophic levels in different food chains (which combine to form a complex food web).
• It gives greater stability to the ecosystem.

​Thus, a group of interconnected food chains is called a food web.

Additional Information

Pyramid of Biomass:

• A biomass pyramid is a diagram that compares the biomass of different trophic levels within an ecosystem.
• It shows the mass of producers that are needed to support primary consumers, the mass of primary consumers required to support secondary consumers, and so on.

Shark, Barracuda and Whale are types of aquatic animals but Humming is a bird.

The correct answer is To adjourn the Legislative Assembly.

• Article 174, a governor shall summon the House at a time and place, as she or he thinks fit.
• Article 174 (2) (a) says a governor may from “time to time” prorogue the House.
• Article 174 (2) (b) allows her or him to dissolve the Legislative Assembly.
• The speaker of the Legislative assembly has the right to adjourn the Legislative Assembly.

Key Points

• According to Article 153, each state in the country will have a governor.
• Also, a person can be appointed as the Governor of two or more states.
• According to Article 155, the Governor is appointed by the President.
• The powers of Governor :
  • The governor has the right to call the state assembly in any emergency and dissolve it at any time.
  • He also has the right to call a joint sitting of the two houses.
  • He has the right to repeal any bill to be passed in the State Legislative Assembly, sent back for review and sent to the President.
  • This means that no bill in the state assembly can be passed without the consent of the governor.
  • The Governor also has the task of issuing any ordinance during emergencies in the state.

Here the pattern is,
