Answer;
-D. Consumer,carnivore,predator
Explanation;
-Within an ecological food chain, consumers are categorized into three groups: primary consumers, secondary consumers, and the tertiary consumers. Primary consumers are usually herbivores, feeding on plants and fungus. Secondary consumers, on the other hand, are mainly carnivores, and prey on other animals.
-A carnivore is an organism that mostly eats meat, or the flesh of animals. Sometimes carnivores are called predators.
-Predators are part of a food chain, the process of passing energy from one organism to the next. Predators that eat primary consumers are known as secondary consumers, which are also eaten by tertiary consumers or quaternary consumers. All of these are just layers of animals that eat from the lower layers.
