ENERGY FLOW AND THE FOOD CHAIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How might a lack of sunlight disrupt the food web?
A
It would cause consumers to consume less.
B
It would prevent decomposers from decomposing matter
C
It would prevent producers from producing nutrients.
D
It would not disrupt the food web at all.
Explanation: 

Detailed explanation-1: -Because the vast majority of producers on earth use photosynthesis to derive their food from sunlight, a lack of sunlight might disrupt this food production. Because the level of light is sometimes unpredictable, these organisms have adaptations to store energy in the event of cloudiness, nigh time, etc.

Detailed explanation-2: -The Sun’s energy is needed for plants to make food through a process called photosynthesis. In photosynthesis, green plants capture the Sun’s energy. They use it to make sugars from water and carbon dioxide. Plants are considered a producer in the food chain.

Detailed explanation-3: -Without the action of the producers to turn sunlight into food, the producers would die, and consumers that rely on them would lose their food source and die too.

Detailed explanation-4: -3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.
