<h2>Sea star </h2>
Explanation:
In the given example sea star played the role of keystone species
- Robert Paine actually coined the term keystone species to describe the effect that the sea stars had on biodiversity in this community
- Keystone species are those species which are least abundant but play a governing role to decide the structure and function of community
- Loss of keystone species in a community can lead to disturbance in structure and function of a community and it cannot be recovered by other species
The answer is; UV (ultraviolet)
The security pens use UV light to illuminate some marking on an object,such as a watermark, to identify its authenticity or owner. The markings are usually invisible to the naked eye under visible light. The marks are only visible when illuminated with UV light. This is because the marking is made of a fluorescent material that absorbs light of a shorter wavelength (this case UV) and emits a longer wavelength (this case visible light).
