Understand the concept of an apex consumer: In ecology, an apex consumer, also known as an apex predator, is a species that is at the top of the food chain and has no natural predators. These organisms play a crucial role in maintaining the balance of ecosystems by controlling the population of prey species.
Identify the characteristics of an apex consumer: Apex consumers are typically carnivorous and have adaptations that allow them to hunt and capture prey effectively. They are essential for regulating the populations of other species within their ecosystem.
Examine the options provided: The problem lists several types of species, including decomposers, primary producers, and herbivores, along with an example of an apex consumer.
Evaluate each option: Decomposers like fungi break down organic material, primary producers like grass create energy through photosynthesis, and herbivores like rabbits feed on plants. None of these fit the definition of an apex consumer.
Select the correct example: The lion is an example of an apex consumer because it is at the top of the food chain and has no natural predators, fitting the definition provided.
