Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organism is most directly dependent on the Sun for survival?
A
carnivores
B
herbivores
C
producers
D
consumers
Explanation: 

Detailed explanation-1: -Plants use energy from the Sun to create organic matter.

Detailed explanation-2: -Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms.

Detailed explanation-3: -The plants use 90% of the energy that they get from the sun to fuel the plants own life processes. Consumers then can be said to get their energy indirectly from the sun but receive only 10% of the energy level of the producers.

Detailed explanation-4: -Living organisms on Earth are dependent on the sun for energy, which they must receive in some form in order to survive. Organisms called autotrophs have the ability to directly capture the sun’s energy and use it to make food.

Detailed explanation-5: -Most life on earth uses the sun as its power source. Trees and plants use the energy in sunlight to combine water and carbon dioxide to make sugars, providing food for all different animals, including humans. This process is called photosynthesis.
