________occurs in equatorial regions where rainfall and warmth are abundant, while________biomes lacks rain.

Options

A. Desert,temperate
B. Tropical rain forest, desert
C. Tundra, savannah
D. Desert, chapparal

Explanation

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

### Step-by-Step Solution:

1. **Understanding Biomes**:
- A biome is a large ecological area on the Earth's surface, with flora and fauna (plants and animals) adapting to their environment. Biomes are characterized by their climate, vegetation, and wildlife.

2. **Identifying 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 warm climate and high levels of rainfall, typically ranging from 90 to 160 cm annually. This biome is found near the equator and is characterized by dense vegetation and high biodiversity.

3. **Identifying the Second Biome**:
- The second part of the question mentions a biome that lacks rain.
- The desert biome is characterized by hot and dry conditions, with very little precipitation. Deserts have extreme temperature variations, with high temperatures during the day and significantly cooler temperatures at night.

4. **Final Answer**:
- Therefore, the first blank should be filled with "tropical rainforest," and the second blank should be filled with "desert."
- The complete answer is: "Tropical rainforest occurs in equatorial regions where rainfall and warmth are abundant, while desert biomes lack rain."
