A rainforest ecosystem is a dense forest characterized by high rainfall, warm temperatures, and a rich diversity of plant and animal life. These ecosystems are typically found near the equator, where conditions are ideal for growth. Rainforests are divided into layers, including the emergent layer, canopy, understory, and forest floor, each hosting unique species. Rainforests play a crucial role in the Earth's climate and oxygen production. They absorb large amounts of carbon dioxide and release oxygen through photosynthesis. Additionally, they provide habitat for countless species, many of which are not found anywhere else, making them vital for biodiversity conservation.
