Answer: (A)

Verified step by step guidance

1. Understand the concept of ecological niches: A generalist species can thrive in a wide variety of environmental conditions and utilize a range of resources, while a specialist species has a narrow ecological niche and relies on specific conditions or resources.
2. Analyze the opossum's behavior and adaptability: Opossums are known to eat a wide variety of foods, including fruits, insects, small animals, and even garbage, which indicates they are not limited to specific resources.
3. Consider the opossum's habitat: Opossums can live in diverse environments, such as forests, urban areas, and rural regions, showing their ability to adapt to different conditions.
4. Eliminate incorrect options: The opossum is not an autotroph (organisms that produce their own food, like plants) or an obligate parasite (organisms that depend entirely on a host for survival). These options are unrelated to the opossum's ecological niche.
5. Conclude based on evidence: Given the opossum's wide range of diet and adaptability to various habitats, it fits the definition of a generalist species.
