Rainforest

A rainforest is a dense forest characterized by high annual rainfall, and is home to a diverse range of plants and animals. These ecosystems are found in tropical and subtropical regions, and are vital to the health of the planet due to their role in regulating the global climate and supporting a wide array of biodiversity.

Key Characteristics of Rainforests

• High rainfall: Rainforests receive a significant amount of rainfall throughout the year, often exceeding 100 inches annually.
• Biodiversity: Rainforests are home to a vast array of plant and animal species, many of which are unique to these ecosystems.
• Canopy structure: The canopy layer of the rainforest is characterized by a dense covering of tree branches and leaves, creating a multi-layered ecosystem.
• Rich soil: Despite the abundance of plant life, the soil in rainforests is often nutrient-poor, as the rapid decomposition of organic matter leads to a continuous cycle of nutrient uptake by plants.
• Threats: Rainforests face numerous threats, including deforestation, climate change, and habitat fragmentation, which have significant impacts on the health of these ecosystems.
