I would go with mathmatical formula because of physics and what not but I'm not completely sure so if you have a different possible answer you think would be better, go with that :)
Answer:
The development of a protostomed organism begins with a spiral development. The mesoderm divides and forms the celoma. There is formation of the celloma from the blastoporo.
The development of a deuterostomy organism begins with radial and indeterminate segmentation. Archaenteron evaginations occur and celoma is formed. The anus develops from the blastoporo and the mouth from a secondary opening.
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.
