Specialist vs Generalist Species Concepts

Ms. Sewart explains the differences between specialist and generalist species, highlighting their characteristics, advantages, and disadvantages. Specialist species, like pandas, have narrow niches and specific needs, making them prone to extinction. Generalist species, like raccoons, have broad niches and adaptability, allowing them to thrive in various environments. The lesson includes examples, comparisons, and a practice question to reinforce understanding.
