Explanation:
Two common types of oils are animal oil and vegetable oil.
Some of the commonest sources of animal oils are from the livers of the
cod and halibut, two kinds of fish. These oils are very nourishing. They are a
great source of vitamins, and hence are recommended for under nourished
children. We get oil from other creatures as well, but it is the whale that yields
the most. The whale has a thick coating of fat called blubber which protects it
from the extreme cold of the Arctic seas. Whales are often hunted for this oil.
To make this oil fit for human consumption blubber is stripped off from a dead
whale and boiled, most often on board the ship.
Vegetable oils are extracted from different plant parts such as seeds, nuts
and the flesh of fruits. They are widely used in cooking. From very ancient
times they have been used in households for various reasons. The oils of
certain flowers are extracted to make perfumes. Vegetable oils such as castor
oil are used as medicine and as lubricants. In recent times, there have been
debates on using waste vegetable oils as fuel.
