Answer:
c. This statement is true because plants are able to convert sun energy into food energy and animals must get their energy from plants or other organisms that eat plants.
Explanation:
Green plants are autotrophs. They synthesize their food in the presence of sunlight, using carbon dioxide gas and water. Whereas animals are heterotrophs, they cannot make their food but use food prepared by green plants. Thus, plants are able to convert sun energy into food energy and animals must get their energy from plants or other organisms that eat plants. The statement is true.
The correct answer is option D

Reducing the amount of green house gases will help in the reduction of the global warming.
One benefit to scientific use of SI units (or International System of Units) is that they are universal - which means that the same type of units is used everywhere in the world. America is one of the rare countries that doesn't use it, which may impede understanding.
