Answer:
Sponges have three asexual methods of reproduction: after fragmentation; by budding; and by producing gemmules.
Explanation:
Various methods of reproduction in sponges increase the population of the sponges on the planet earth and also support longevity of sponges.
The multiple methods of reproduction support the longevity of sponges in the fossil record because the various methods of reproduction increase the survival as well as the population of sponges on the planet earth which also increase the life of the sponges.
If the sponges use only one method of reproduction then they will not increase its population very efficiently. Sponges are able to reproduce through sexually by using gametes as well as asexually by budding so we can conclude that these methods increase the population of the sponges on the planet earth and support longevity of sponges.
