Option C) are capable of living independently is not supported by the endosymbiosis theory concerning organelles
Explanation:

- These organelles have their own separate DNA.
- The separate DNA present in them is capable of making their own proteins.
- They are membrane- bound organelles.
However, these organelles can now not live separately outside of the cell. This might be because of the evolutionary changes which occurred in these cells during the long period of time.

Answer:
Grinnell was the scientist who coined the term niche. An ecological niche the place where the species and their members live together. Niche is quite different from habitat.

For example, a lake can be considered as a habitat for fish but a lake can provide a different niche for fishes. A big fish hunting a small fish in a portion of a lake is a niche and a small fish hunting an insect in another portion of the lake is another niche.
