About the Rainforest and Amazon River
How does the Rainforest Support Different Varieties of Organisms?
The rainforest's climate and canopy are the biggest factors that support the vast amounts of organisms in rainforests.
How Biodiversity Contributes to the Sustainability of the Amazon River
By Aarushi Panjwani
My Biome: Rainforest
Its Ecosystem: Amazon River
Essential Biotic and Abiotic Factors in Rainforests
Short-Term Environmental Changes
Long-Term Environmental Changes
Birds (parrots, hornbills, toucans, and raptors like eagles, hawks, and vultures)
Reptiles (snakes, lizards, turtles, tortoises, and crocodiles)
Amphibians (frogs, toads, salamanders, newts, and worm-like caecilians)
Arthropods and other invertebrates
Rainforests are dense forests with of biodiversity that experience lots of rainfall. They are home to 40% to 75% of all biotic species.
The Amazon River
The Amazon River is the second largest river in the world. It is located in the Amazon Rainforest and carries nearly more water than any other river in the world. The Amazon River is habitiat to many unique animals.
Rainforests have very tropical climates, therefore they recieve a lot of sunlight. Because of the tropical climate, there is a lot of vegetation. This vegetation stores a lot of energy, and gets eaten by many animals. The rainforest's climate creates vast amounts of energy and vegetation that supports the vast varieties of organisms.
The canopy section of a rainforest provides a place for many organisms to grow and thrive. Canopies also provide food, shelter, and hiding places for different animals and plants. The canopies also provide interactions between different organisms. For example, plants called bromeliads store water in their leaves, some amphibians use these leaves for their eggs.
Many would think wildlife would be like "survival of the fittest," but every organism depends on the survival of another. For example, in the Amazon River, the boto dolphin eats the piranha and golden dorado. If the boto dolphin becomes extinct, there would be an abundance of piranhas and golden dorados. If golden dorados become extinct, the boto dolphin will eat only piranhas which will cause the population of piranhas to decrease. This would also happen to the golden dorado's population if the piranhas became exctinct. In conclustion, if one organism is taken away from an ecosystem, it will effect other organisms.
One long-term environmental change occuring in the Amazon River is climate change. Climate change results in different amounts of rainfall in a region and different temperatures in a region. Because of the climate change, water levels in the Amazon River have decreased drastically. With the large demand for water in this ecosystem, many organisms will die due to the lack of water.
Another long-term environmental change that has been affecting the Amazon River is urbanization of South America. The population in South America is increasing drastically. As a result, more homes for these people need to be built. Builders have started to use the rainforest as land for these homes. This has affected the organisms in the Amazon River by taking away their habitats.
One short-term environmental change that has taken place in the Amazon River ecosystem is the drought of 2005. This drought has made the Amazon Rainforest the driest it has ever been in 60 years. Many rivers, including the Amazon River, dried out or had water levels decrease extremely. This made a big impact on the Amazon River by increasing the need for water drastically and causing the populations of many organisms to decrease.
Another short-term environmental change that has occurred in the Amazon River is flooding. This creates too much water than what the organisms need. Therefore, organisms in the Amazon River are affected greatly. Many trees live underwater for 5-6 months. Fish predators also experience great difficulty hunting their prey because fish have a larger habitat due to the flooding. Also some unique fruit eating fish that live in the Amazon River thrive during flooding times because the water gets so high, they are able to reach the fruit on the trees.
