Succession in water ultimately results in __________ condition.

Step-by-step solution

Succession in water is known as hydrarch succession. It begins in a water body where conditions are highly wet (hydric). As succession progresses, the water body gradually fills with organic matter and sediments, leading to the formation of a marsh, then a swamp, and eventually a forest. The climax community is a forest, which represents a medium moisture environment. Therefore, hydrarch succession ultimately results in a mesic condition, which is neither too dry (xeric) nor too wet (hydric). Answer: mesic
