A Correct answer
Explanation

Ecosystem services are the direct and indirect benefits that humans derive from ecosystems, including provisioning, regulating, supporting, and cultural services that have economic and aesthetic value.

In an ecosystem which of the following are important components?

  1. Energy flow and food chain

  2. Mineral recycling and energy flow

  3. Food chain and decomposers

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

Any ecosystem has two components -biotic or living organisms and abiotic or non-living component. 

Further, two most important functional characteristics of any ecosystem are unidirectional flow of energy and cycling of material. The living organisms of an ecosystem are related through food chains, which gives rise to trophic levels in an ecosystem. Energy is transferred from one trophic level to the next through the food chains. 
Of all the organisms in an ecosystem, the most important role is played by decomposers. The nutrients are released back into the environment by the decomposition of dead organisms. Thus, the correct answer is option D.

Which one of the following is the most stable ecosystem?

  1. Forest

  2. Mountain

  3. Desert

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

The ocean is considered the most stable ecosystem because it has a high heat capacity, vast volume, and relatively constant chemical and physical conditions compared to terrestrial ecosystems like forests or deserts.

Fuel powered ecosystem is also known as

  1. Urban industrial Ecosystem

  2. Unsubsidized natural solar powered ecosystem

  3. Naturally subsidized solar powered ecosystem

  4. Man subsidized solar power ecosystem
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Urban industrial ecosystems are often referred to as fuel-powered ecosystems because they rely heavily on external energy sources (fossil fuels) rather than just solar energy to maintain their structure and function.

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

  1. Energy recycling

  2. The energy pyramid

  3. The biotic/abiotic cycle

  4. The carbon cycle
Reveal answer Fill a bubble to check yourself
D Correct answer
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
Reveal answer Fill a bubble to check yourself
A Correct answer
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.
