The correct Answer is:
To solve the question, we need to analyze the two statements provided and determine their validity based on the concept of ecological equivalents. ### Step-by-Step Solution: 1. **Understanding Statement 1**: - The first statement claims that the cow in India and the kangaroo in Australia are ecological equivalents because both are herbivores. - Ecological equivalents are organisms that occupy similar ecological niches in different geographical areas. 2. **Understanding Statement 2**: - The second statement defines ecological equivalents as organisms that have smaller niches in different geographical regions. - This definition aligns with the concept of ecological equivalents, which emphasizes similar niches in different habitats. 3. **Analyzing Statement 1**: - Cows and kangaroos both feed on plants and thus share a similar ecological role as herbivores. - However, they exist in different geographical locations (India and Australia), which supports the idea of them being ecological equivalents. 4. **Analyzing Statement 2**: - The statement correctly describes ecological equivalents as organisms that occupy similar niches in different geographical areas. - The term "smaller niche" might be misleading; it is more about the similarity of the niche rather than its size. 5. **Conclusion**: - Both statements are correct. Statement 1 correctly identifies the cow and kangaroo as ecological equivalents, and Statement 2 accurately describes the concept of ecological equivalents. - Therefore, the correct option is that both statements are true. ### Final Answer: Both Statement 1 and Statement 2 are correct. ---
