Tertiary Consumers

In an ecosystem, tertiary consumers are organisms that occupy the highest trophic level in a food chain or food web. They are top predators that feed on secondary consumers and sometimes other tertiary consumers. Tertiary consumers are crucial for maintaining the balance of the ecosystem.

Characteristics of Tertiary Consumers

• They are typically large predators such as big cats, sharks, and large birds of prey.
• They have few or no natural predators.
• They play a crucial role in controlling the population of organisms at lower trophic levels.

Examples of Tertiary Consumers

Examples of tertiary consumers include:

• Lions
• Killer whales
• Golden eagles
• Large sharks
• Humans (in some ecosystems)
