Here's why:

* Abiotic factors are non-living components of an ecosystem.

* Rainforests are known for their consistently high temperatures, rarely dipping below 68°F (20°C) even at night. This warmth is crucial for supporting the lush plant and animal life found in rainforests.

Other abiotic factors in a rainforest include:

* Sunlight: Rainforests receive a lot of sunlight, which is essential for plant photosynthesis.

* Water: Rainforests receive abundant rainfall, which is vital for plant growth and the survival of many animals.

* Soil: Rainforest soil can be very fertile, but it is also prone to erosion due to heavy rainfall.

* Humidity: Rainforests have high humidity levels, which helps maintain the rainforest environment.

* Air Quality: Air quality is affected by rainfall and plant life, creating a unique atmosphere within the rainforest.
