Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which most accurately describes how plants and animals get the energy they need for growth and survival?
A
Molecules are broken down during respiration to release stored energy.
B
Molecules are broken down during photosynthesis to release stored energy.
C
Animals produce energy through photosynthesis, while plants produce energy through respiration
D
Animals produce energy through respiration, while plants produce energy through photosynthesis.
Explanation: 

Detailed explanation-1: -A. In respiration, molecules are broken down in order to release the stored energy in the chemical bonds. Both animals and plants use respiration to release stored energy. As such, this is correct.

Detailed explanation-2: -Lesson Summary. Photosynthesis is how plants combine light, water, and carbon dioxide to produce energy (glucose) and oxygen. The glucose powers the plants functions, and the oxygen is released back into the atmosphere. Cellular respiration is how animals combine glucose and oxygen to produce carbon dioxide and water.

Detailed explanation-3: -During photosynthesis, carbon dioxide, a gas, is combined with water and solar energy, and converted to carbohydrates, a solid. Formation of carbohydrates is a chemical way to store the sun’s energy as “food.” Carbohydrates produced from photosynthesis provide energy for all plant growth and maintenance.
