Answer: (B)

Verified step by step guidance

1. Step 1: Begin by understanding the concept of a 'niche' in ecology. A niche refers to the role an organism plays in its ecosystem, including its interactions with other organisms and its environment.
2. Step 2: Analyze the options provided. Each option describes a different ecological role: decomposer, top predator, scavenger, and primary producer. Consider the characteristics of a lion in its natural habitat.
3. Step 3: Recall that lions are carnivorous mammals that primarily hunt large herbivores such as zebras and antelopes. They are not decomposers, scavengers, or primary producers.
4. Step 4: Understand the ecological impact of lions. As top predators, they help regulate prey populations, maintaining balance in the ecosystem. This is a key aspect of their niche.
5. Step 5: Based on the analysis, identify the option that best aligns with the lion's role in its natural habitat: 'A top predator that hunts large herbivores and helps regulate prey populations.'
