All animals are consumers and they are also known as heterotrophs. There are different types of consumers. They include; primary consumers (herbivores e.g. goats, cows), secondary consumers (carnivores e.g. wolves, crocodile), and tertiary consumers (large carnivores e.g. eagle, lion)

The correct answer is -

d. consumers.

Consumers can be defined as organism that obtain their food by consuming organic matter from other organisms because they can not synthesise own food from inorganic sources (unlike producers such as plants, which synthesise their own food).

There can be different levels of consumers such as primary consumer, secondary consumer, and tertiary consumer.

Primary consumer such se rabbits feed on vegetables /fruits such as carrots. They are known as herbivores.

Secondary consumers consume primary consumers, similary tertiary consumers are dependent upon secondary consumers.
