Question

1) This is an organism that gains energy by eating only plants.

Answer 1

Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water. Animals cannot make their own food so they must eat plants and/or other animals. They are called consumers.

Answer 2

Herbivores eat only plants, whereas carnivores eat meat, and omnivores (humans fall in this category) eat plants as well as meat
