Forest ecosystem – the amazon
A forest ecosystem is the community formed by plants and animals of this particular environment that interact with the chemical and physical features of the environment in which they live. The amazon rain forest is an example of a forest ecosystem.
The amazon is a vast region that spans across many rapidly developing countries such as Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, Suriname, and French Guiana. The amazon is home to a wide variety of plant and animal species, which include producers, consumers and decomposers. These organisms are interdependent on each other for survival. In the amazon there are 1 in 10 known species on earth, this shows just how many rare species there are living in one example of a forest ecosystem.
Forests take up approximately 751 million acres, which is about 1 third of the country’s total land area. Forests require protecting as they can provide many benefits and services to society. Including clean water, recreation, wildlife habitat, carbon storage, and a variety of forest products. Climate influences the structure and function of forests ecosystems and plays an essential role in forest health. A changing climate may worsen many of the threats to forest, such as pest outbreaks, fires, development, and drought.
There is a clear link between the health of the amazon and the health of the planet. The rain forests, which contain 90-140 billion metric tons of carbon, help to stabilise local and global climate. Deforestation may release significant amounts of carbon, which could have catastrophic consequences around the world.
Desert ecosystem – Sahara desert
The Sahara desert is an example of a desert ecosystem; it is located in the Northern portion of Africa and covers over 3,500,000 square miles or roughly 10% of the continent.
The harsh conditions found in the Sahara desert have also played a role in the presence of animal life living
