Based on the information provided, the ecosystems that show where early civilizations developed because the area allowed people to grow crops even during times with little rainfall are:

- Desert
- Sahel
- Savanna

To determine which ecosystems show where early civilizations developed because the area allowed people to grow crops even during times with little rainfall, we need to understand the characteristics of each ecosystem listed in the options.

1. Desert: Deserts typically have little rainfall, making it difficult to grow crops without the presence of water sources such as oases or river valleys.

2. Rainforest: Rainforests receive high amounts of rainfall, which may not align with the condition mentioned in the question.

3. Savanna: Savannas have a mix of grasslands and trees and can support agricultural activities, even during times with little rainfall. Therefore, savannas are a potential ecosystem where early civilizations could have developed.

4. Sahel: The Sahel is a transitional zone between the Sahara Desert and the savannas further south. It has semi-arid conditions with limited rainfall but can still support some agricultural activities.

Based on these explanations, the correct options that show where early civilizations developed because the area allowed people to grow crops even during times with little rainfall are:

- Savanna
- Sahel
