Explanation

To answer the question, we need to identify two types of biomes based on the characteristics provided: one that occurs in equatorial regions with abundant rainfall and warmth, and another that lacks rain.

### Step-by-Step Solution:

1. **Identify the first biome**:
- The question states that the first biome occurs in equatorial regions where rainfall and warmth are abundant.
- The tropical rainforest is known for its high levels of rainfall (between 1750 mm to 2000 mm annually) and warm temperatures. It is characterized by a diverse range of plant and animal species due to the favorable climate.

2. **Identify the second biome**:
- The second part of the question refers to a biome that lacks rain.
- The desert biome is defined by its very low precipitation (less than 250 mm annually). Deserts are characterized by extreme temperatures and sparse vegetation.

3. **Fill in the blanks**:
- Based on the analysis, we can fill in the blanks in the question:
- The first blank is "tropical rainforest," and the second blank is "desert."

### Final Answer:
**Tropical rainforest occurs in equatorial regions where rainfall and warmth are abundant, while desert biomes lack rain.**
