• C. A is true and R is false
• D. Both A and R are false

Answer 1

The correct option is A Both A and R are true and R explains A

All living organisms need energy, from the smallest bacteria to the largest mammals. Plants are the only organisms that can manufacture their own food from nonliving sources by the process of photosynthesis. Herbivores survive on plants for food and derive their energy from plants. Carnivores or flesh eating animals in turn depend on herbivores, therefore they indirectly derive energy from plants.
