ENERGY FLOW AND PRIMARY PRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following methods is how primary producers obtain energy?
A
Use the sun to produce energy rich compounds
B
Produce CO2 through cellular respiration
C
Break down chemicals to produce energy rich compounds
D
Consuming other organisms
Explanation: 

Detailed explanation-1: -The best-known and most common primary producers harness solar energy through the process of photosynthesis. Photosynthesis captures light energy and uses it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates.

Detailed explanation-2: -Complete answer: 1)Mostly the plants are producers, which means they are capable of converting the sunlight that is the solar energy into chemical energy. The entire process of this energy conversion is known as photosynthesis.

Detailed explanation-3: -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.

Detailed explanation-4: -Consumers constitute the upper trophic levels. Unlike producers, they cannot make their own food. To get energy, they eat plants or other animals, while some eat both.

Detailed explanation-5: -The food chain in which the microorganisms break down the compounds synthesized by producers that are rich in energy is the Detritus food chain (DFC).
