Tertiary consumers and apex predators, including big fish, marine mammals, and humans, form the top trophic levels. They drift across the ocean's surface, grazing on whatever they come across. Despite their differences in size, herbivores share a voracious appetite for ocean vegetation. When top predator species are depleted, their numbers are often slow to rebound, and their loss can send shock waves through the entire food web. These apex predators tend to be large, fast, and very good at catching prey. way of classifying lakes based on the amount of nutrients the lakes possess. © 1996 - 2020 National Geographic Society.
