Answer 1

1. The first law of thermodynamics states that energy or matter neither ceated nor destroyed. Energy can be converted to one form to other, it can be transported and stored. A living organism is an example of all forms of energy that is converted, transported and stored and when the organism or animal dies, the energy is distributed into nature. Therefore, the given statement is true.

2. Plants carryout photosynthesis using sunlight and carbon dioxide to produce carbohydrates. The carbohydrates synthesized by photosynthesis are utilized to produce energy in the form of ATP and this ATP is used for various metabolic activities like sugar and water transport, growth and reproduction of plants. Therefore, the given statement is true.
