Final answer:
Carnivores are the organisms that eat other animals and among the options provided, only 'carnivores' accurately hit the mark. Consumers, decomposers, and producers are classifications of organisms based on their source of food and method of energy acquisition, but only carnivores specifically feed on other animals.
Step-by-step explanation:
Which Organisms are Carnivores?
Among the options provided, carnivores are the organisms that feed on animals, either herbivores or other carnivores. Examples of carnivores include lions, polar bears, hawks, frogs, salmon, and spiders. Some carnivores are obligate carnivores, meaning they can only eat animals because they cannot digest plants, while other carnivores can digest both but primarily consume animal matter.
Consumers are organisms that depend on other organisms for food and include all animals, which means they can be herbivores, omnivores, or carnivores. Decomposers, like fungi, are actually consumers that break down dead organisms for energy but do not fit the category of carnivores. Producers, such as plants, are the base of food chains and are not considered carnivores as they produce their own food via photosynthesis. Omnivores consume both plants and animals, examples include humans and bears, but they are not exclusive carnivores.
