The invasive species are the species who are present in a non native ecosystem. The invasion of These species disturbs the environment of particular system by increasing the competition or destroying the vital component of the ecosystem.
The invasive species can increase the competition in the native species, which would lead to the decrease in the number of the native species. There are many species present in the Hawaii department of the agriculture that are endangered, the competition cannot be tolerated here, as it can lead to the extinction of the endangered species present. So, in order to reduce the chance of the extinction due to competition, Hawaii department of Agriculture is very strict about the prevention of the non native or invasive species.
Answer:
The Articular cartilage.
Explanation:
Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Healthy cartilage in our joints makes it easier to move. It allows the bones to glide over each other with very little friction. Articular cartilage can be damaged by injury or normal wear and tear.
