In a pond, which of the following changes would most likely result in terrestrial succession (turning the aquatic ecosystem into a land ecosystem)?

An increase in water plants growing in the pond.

A decrease in the number of decomposers in the pond.

An increased rate of deposition of sediments into the pond.
