Final answer:
The tropical rainforest is one of the most threatened ecosystems, losing about 150,000 km2 annually due to deforestation and other forms of habitat destruction. This loss influences ecosystem diversity and leads to the extinction of many unique species which have been adapted to live in these conditions.
Step-by-step explanation:
One of the most threatened ecosystems is the tropical rainforest, which is experiencing a loss of about 150,000 km2 of area per year. Tropical rainforests, such as those in the Amazon Basin, are the most biologically diverse ecosystems on the planet. They are, however, being devastated quickly by deforestation and other forms of habitat destruction, driving many rare species with limited habitats to extinction. Ecosystem diversity signifies the number of distinct ecosystems on the planet or within a particular region. The loss of an ecosystem entails the loss of species interactions, unique features of coadaptation, and valuable biological productivity that the ecosystem can generate. Examples of extinct ecosystems include the prairie ecosystems in North America, which have been largely replaced by agricultural and urban areas.
