It means that all the organisms in that community rely on one another to survive.
Not just a woman, but any astronaut:
The air in the suit would rush out, lungs will collapse and you will pass out in 15 seconds (That's how long it takes the body to use up the oxygen). Death by oxygen deprivation
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.
