Ecology Niches, Realized And Fundamental?


5. Meadowfoam can be found growing in marshes and surrounding meadows. Bladderwort can be found growing in marshy habitats. When meadowfoam and bladderwort are found growing together, bladderwort is found growing in the marsh and meadowfoam is found in the meadow. Which of the following is correct.
a. The fundamental niches of meadowfoam and bladderwort are the same.
b. The realized niches of meadowfoam and bladderwort are the same.
c. The fundamental and realized niches of bladderwort are the same.
d. The fundamental and realized niches of meadowfoam are the same.
e. None of the above.
I am aware that fundamental niches are what the species can live in. And realized is what they species will actually live in.
So I would assume that the answer is “none of the above” since the fundamental niches are different since they both live in the same area normally. And since they both don’t occupy the same area when living together they are not the same.
Is this correct?

How Are Snake Holes A Niche?


I’m doing an ecology project where we had to go out and take pictures of lots of symbiotic relationships and my teacher mentioned that snake holes were niches. WHY are snakeholes niches?
