* Sunlight: Rainforests receive abundant sunlight, especially in the upper canopy layers. This sunlight fuels photosynthesis, driving the rainforest ecosystem.

* Temperature: Rainforests are typically warm and humid, with temperatures remaining relatively stable throughout the year. This consistent warmth supports a wide range of plant and animal life.

* Rainfall: Rainforests are defined by their high rainfall, often exceeding 200 cm (80 inches) annually. This constant rainfall provides the water necessary for plant growth and sustains the rainforest ecosystem.

* Soil: Rainforest soils are often nutrient-poor due to rapid decomposition and leaching. However, they are rich in organic matter and support a vast array of plant life.

* Humidity: The high levels of rainfall create extremely humid conditions in rainforests. This humidity is essential for many rainforest organisms and contributes to the dense, lush vegetation.
