The introduced species are usually defined as those species that are entirely new to an ecosystem or biodiversity, and are not native to that particular place. They can occur naturally and can also be transported by humans. They are commonly considered as exotic species.
The appearance of these species can cause great harm to the biodiversity. It can cause changes in the food-chain within an ecosystem. They can outnumber the native species. They can also consume all the food present in an ecosystem and can causes changes in the habitat. The process of hybridization can also take place with the native species.
The property of carbon that allows it to make very large organic molecules would be the ability of carbon to form a maximum of 4 covalent bonds. Due to its 4 valence or outermost electrons.
