False false false. Biology is a very dynamic science because we are still discovering new species. As our technology advances, we are learning more than ever before. Case in point: when moi' was in school, there were only 3 kingdoms! The atom only contained 3 particles. Pluto was a planet. Man had never been to the moon! Look at us now!
Natural changed to the ecosystem relate to environmental shock that occur naturally. Natural changes include floods, volcanic activity, hurricanes, etc. They can be destructive, but they also have advantages. Floods have the contribution of nutrients to the soil which was lacking. It can also relocate fishes and organisms living in bodies of water which improves the ecosystem.
The right action is capillarity (or capillary force).
Capillarity is the interaction phenomenon that occurs at the interfaces between two immiscible liquids, between a liquid and air or between a liquid and a surface. It is due to the forces of surface tension between the different phases in the presence. It is used when the blotters suck the ink, the sponges soak with water, or when we dip some of its sugar in its coffee and that sugar becomes all black.
