The distribution of plants in a rainforest is mainly governed by the rainfall pattern. Rainforests are characterized by high levels of rainfall and humidity, and these conditions play a crucial role in determining the distribution of plant species within the ecosystem. The amount and distribution of rainfall is a key factor in determining the availability of water for plants, and this in turn affects their growth and survival. In a rainforest, plant species are distributed according to their tolerance for varying levels of moisture and light. Some species require large amounts of water and can only grow in areas that receive high levels of rainfall, while others can tolerate drier conditions and can be found in areas with lower levels of rainfall. Overall, rainfall patterns are the main factor governing the distribution of plants in a rainforest, as they determine the availability of water and the conditions under which different plant species can survive and thrive.
