Given what we know, the example that most appropriately described an organism's niche is that Panda bears have a very limited diet, primarily feeding on bamboo in their environment.
<h3>What is a niche in ecology?</h3>
- It is described as a role filled by an organism.
- This role or trait is specific to the environment of the organism.
- It describes the adaptation of the organism to the resources present.
Therefore, given the definition of a niche as an adaptation or role filled by an organism that is specific to their environment, we can confirm that the example with the panda bears fits this description since they will only eat bamboo, being the <u>only bear species to not be carnivorous</u>.

Answer:
Part 1. The amount of calcium is independent variable.
Explanation:
An independent variable is a variable in an experiment which is changed to see its effects on dependent variable.
In this experiment, to know about the causes of osteoporosis, the Ca level in blood or calcium intake in changed.
So the concentration of calcium will be independent variable.
Part 2.
The risk of bone fractures is could be changed with calcium.
Explanation:
In this experiment osteoporosis or risk of bone fracture is dependent variable.
Dependent variable are results of experiment which can be changed by independent variable.
As in experiment, Calcium concentration is independent variable.
So the risk of osteoporosis depends can change with calcium.
