The biotic components of an ecosystem include the producers, consumers and decomposers. The consumers are further classified as primary, secondary and tertiary consumers. Primary consumers or herbivores (e.g., rabbit, deer, elephant, snails) feed on the producers. Secondary consumers or carnivores (e.g., cat, jackal, small fish) directly prey upon herbivores. Tertiary consumers or top carnivores are usually large carnivores (e.g., tiger, shark, whale) which feed on secondary consumers and also on some primary consumers, they generally do not have any predators that can prey upon them. Therefore specifically in the given image, the herbivores feeding on the grass can be deer and cow and the top carnivores that feed on deer and cow, can be both tiger and lion.
