BIO1302 Columbia Southern Ecological Biome Animal Species Discussion

BIO 1302 Unit I Journal

Think about the ecological biome where you currently live or grew up. Would you classify it as temperate forest, temperate grassland, or another biome? What are the dominant types of vegetation and animal species that live there? How have human activities changed your biome over time?

Your journal entry must be at least 200 words. No references or citations are necessary.
