Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which statement best describes energy transfer in a food web?
A
Energy is transferred to consumers which convert it to nitrogen compounds and use it to synthesize amino acids
B
Energy from producers is converted into oxygen and transferred to consumers
C
Energy from the sun is stored in green plants and transferred to consumers
D
Energy moves from autotrophs to heterotrophs to decomposers, which recycle it back into a form producers can use again
Explanation: 

Detailed explanation-1: -Correct answer: Energy flows from producers to consumers. Explanation: Energy flows from producers to consumers. Plants (producers) indirectly provide energy to all members of the food chain.

Detailed explanation-2: -Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.

Detailed explanation-3: -Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.

Detailed explanation-4: -According to the First Law of Thermodynamics, energy is neither created nor destroyed and only transferred or converted from one form to another. This principle holds true in ecosystems, where energy is constantly transferred across the food web.
