The butterfly finds flowering plants for nectar in the meadow. In the process of sucking nectar, they pollinate the plants. The meadow plants such as grasses, forbs and sedges plants provide food for field mice that eat their leaves , roots, and bulbs. The mice also create burrows in the meadow where they breed their young. This, therefore, provides a good hunting ground for owls that prey on mice.

(a) Total power of magnification 100x because ocular lens is 10x magnification maultiplied by 10x objective lens.
(b) Widht of the onion cell can be calculated as follows:
If the number of units observed for an onion cell through ocular micrometer (10x) under microscope is 'A'.
Then, the widht of the cell will become = A X 9.5 (Calibration factor of ocular unit and total power fo magnification is 100x)
So, for example if the observation through ocular micrometer is 13, then the widht of the onion cell will be = 13 X 9.5 = 123.5 μm
Answer:
B. Hermit crabs and fish that hide in shells compete with each other for shelter.
Explanation:
Hermit Crabs hides from their predator by hiding in old seashells (e.g those of gastropods) for protection and/or shelter. This is a form of camouflage exhibited by hermit crabs for survival. Now, if peradventure some species also uses the same mechanism for adaptation and survival, vigorous competition will sets in between hermit crabs and those species because the availability of empty shells ata ny given place depends on the relative abundance of gastropods which is crucial for the survival of both organisms from their predators. Sometimes, they may even have to fight or kill a competitor in order to gain access to the shell that favors them.
