Which of the following cycles is concerned with energy flow in the ecosystem?

Answer: The cycle primarily concerned with energy flow in the ecosystem is the carbon cycle.

Why is the Carbon Cycle Related to Energy Flow?

The carbon cycle is fundamental to energy flow because it involves the transfer of carbon through various components of the ecosystem, which in turn fuels energy flow via processes such as photosynthesis and cellular respiration.

Key Concepts:

  1. Photosynthesis:

    • Plants absorb carbon dioxide (CO_2) from the atmosphere and use sunlight to convert it into glucose (C_6H_{12}O_6) through photosynthesis:
      6CO_2 + 6H_2O + Light \rightarrow C_6H_{12}O_6 + 6O_2
    • This process captures solar energy and converts it into chemical energy (stored in glucose), which is the foundation of energy flow through food chains.

  2. Cellular Respiration:

    • Organisms use oxygen to break down glucose, releasing energy in the form of ATP (adenosine triphosphate), which powers biological processes:
      C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + Energy (ATP)

  3. Transfer Between Organisms:

    • The chemical energy stored in plants (producers) is passed to consumers (herbivores, carnivores) through food chains and food webs.
    • As organisms consume others, energy in the form of carbon compounds flows through the ecosystem.

Ecosystem Cycles Overview

Cycle Core Function Energy Flow Role
Carbon Cycle Involves the flow of carbon through living organisms and the atmosphere. Directly related to energy transfer via photosynthesis.
Nitrogen Cycle Deals with nitrogen fixation and its usage by plants and animals. Supports organic matter synthesis, not directly energy.
Phosphorus Cycle Circulates phosphorus necessary for nucleic acids and ATP. Supports genetic material and energy storage molecules.
Water Cycle Movement of water through evaporation, precipitation, etc. Indirectly impacts energy transfer by maintaining ecosystems.

Conclusion: Carbon Cycle and Energy Flow

The carbon cycle is directly responsible for the flow of energy within an ecosystem because:

  • It captures solar energy through photosynthesis.
  • Transfers energy across trophic levels in food chains.
  • Releases energy during cellular respiration.

Therefore, the correct answer is: Carbon Cycle
