ENERGY FLOW AND THE FOOD CHAIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
We get energy from the food we eat. The energy in the food first comes from the
A
soil
B
fertilizers used by farmers
C
sun
D
vitamins added by food manufacturers
Explanation: 

Detailed explanation-1: -All the energy we get from food can be traced back to the sun. The sun’s energy is transferred to plants, which use it to convert water and carbon dioxide into sugars. That process is called photosynthesis. Plants are then eaten by animals, which are eaten by larger animals.

Detailed explanation-2: -The energy content of all food molecules can be traced back to the Sun. It is the process of photosynthesis that locks the Sun’s energy into simple carbohydrates like glucose.

Detailed explanation-3: -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-4: -Plants use the Sun’s energy to make all their food, through a chemical reaction called photosynthesis, which happens in the green parts of a plant (usually the leaves). Inside the leaves carbon dioxide is combined with water using the Sun’s energy to make a sugar called glucose.

Detailed explanation-5: -We depend upon light energy for food. We all depend either directly or indirectly on the food prepared by plants through photosynthesis in the presence of sunlight.
