The species diversity_________whem we move towards the equator whereas it _______when we move towards the poles.

Answer

**Step-by-Step Solution:**

1. **Understanding Species Diversity**: Species diversity refers to the variety of different species present in a particular ecosystem or geographical area. It is influenced by various environmental factors.

2. **Analyzing the Equator**: As we move towards the equator, the conditions for life are generally more favorable. This includes optimal temperatures, abundant rainfall, and fertile soils. These conditions support a wide variety of species, leading to an increase in species diversity.

3. **Analyzing the Poles**: In contrast, moving towards the poles, the environmental conditions become harsher. The temperatures are extremely low, especially during winter, and the growing season is short. These harsh conditions limit the types of species that can survive, resulting in a decrease in species diversity.

4. **Filling in the Blanks**: Based on the analysis:
- The species diversity **increases** when we move towards the equator.
- The species diversity **decreases** when we move towards the poles.

5. **Final Statement**: Therefore, the completed statement is: "The species diversity **increases** when we move towards the equator whereas it **decreases** when we move towards the poles."
