Regrowth of grasses, ferns, wildflowers, and saplings after a forest fire is an example of secondary succession.
Secondary succession is one of the two main forms of ecological succession of plant life that is initiated by an occurrence such as harvesting, or forest fire, that has a negative impact or diminishes an already established ecosystem such as a forest or a wheat field to a lower number of species. Several factors such as initial composition, trophic interaction, and competition-colonization trade-offs can influence secondary succession.
Fact: <span>Organisms are classified based on their physical characteristics. For example, some organisms have a backbone, and other organisms do not have a backbone. Some organisms are single-celled, and other organisms are multi-celled. The classification order that scientists use is Domain, Kingdom, Phylum, Class, Order, Family,Genus, and Species.
