DENDROLOGY

Detailed explanation-1: -Carnivores eat other consumers. This means they eat other animals. Animals that eat both producers and consumers are called omnivores.

Detailed explanation-2: -The organisms that eat the secondary consumers are called tertiary consumers. These are carnivore-eating carnivores, like eagles or big fish. Some food chains have additional levels, such as quaternary consumers (carnivores that eat tertiary consumers).

Detailed explanation-3: -Consumers have to eat to gain energy or they will die. There are four types of consumers: omnivores, carnivores, herbivores and decomposers. Herbivores are living things that only eat plants to get the food and energy they need. Animals like whales, elephants, cows, pigs, rabbits, and horses are herbivores.
