Detailed explanation-1: -Tropical rain forest have the greatest biodiversity of any type of land ecosystem. How does biodiversity contribute to the sustainability of an ecosystem? The presence of more species with different adaptations makes it more likely that some organisms will survive an ecological disaster.
Detailed explanation-2: -Tropical rainforests are the most biologically diverse terrestrial ecosystems in the world. The Amazon rainforest is the world’s largest tropical rainforest. It is home to around 40, 000 plant species, nearly 1, 300 bird species, 3, 000 types of fish, 427 species of mammals, and 2.5 million different insects.
Detailed explanation-3: -Rainforests have high biodiversity because they are abundant in nutrients, energy and a favorable climate. Tropical rainforests have warm temperatures and lots of precipitation. The high intensity sunlight provides energy for producers in the rainforest and supports a wide variety of plant growth.
Detailed explanation-4: -Biodiversity is essential for sustainable development and human well-being. It underpins the provision of food, fibre and water; it mitigates and provides resilience to climate change; it supports human health, and provides jobs in agriculture, fisheries, forestry and many other sectors.
Detailed explanation-5: -As well as the vivid beauty that comes with great diversity in plants and animals, rainforests also play a practical role in keeping our planet healthy. By absorbing carbon dioxide and releasing the oxygen that we depend on for our survival. The absorption of this CO2 also helps to stabilize the Earth’s climate.
