Secondary succession is where organisms that were part of an earlier successional stage before a disturbance return (forest fire, logging, insect damage). A parachutist is in free fall at a rate of 200 km/h when he opens his parachute at an altitude of 600 m.

C) Colonization of plants happens from the sediments at the lake bottom. are the pioneer species of ecological succession. The plants that are often pioneer species also tend to be wind-pollinated rather than insect-pollinated, as insects are unlikely to be present in the usually barren conditions in which pioneer species grow; however, pioneer species tend to reproduce asexually altogether, as the extreme or barren conditions present make it more favourable to reproduce asexually in order to increase reproductive success rather than invest energy into sexual reproduction.
