Answer:
Option-4
Explanation:
In the given question, S. alterniflora grows in the seaward marsh whereas S. patensis grows in the high marsh. When S. alterniflora is removed, the S. patensis grows to a smaller portion whereas if S. patensis is removed, the S. alterniflora covers all the land.
This shows that although both are different species but they share a niche and the marsh land is the fundamental niche of the S. alterniflora as it can grow in all parts and therefore its distribution is limited by only a realised niche.
Thus, Option-4 is correct.
