This speed capability is vital when the fish will either try to avoid a predator or, if it is a predator itself, catch its prey.
Answer:
Data on distribution of population among the administrative areas are useful for several purposes. They

The concepts of population distribution and density are so closely related to each other that it would be
appropriate to discuss them in the same chapter. However the two concepts are different, as distribution
is based on location while density is a ratio. Population distribution denotes the spatial pattern due to
dispersal of population, formation of agglomeration, linear spread etc. Population density is the ratio of
people to physical space. It shows the relationship between a population and the size of the area in
which it lives.

<u>Answer:</u>
a) The land which supplies water to a "river system" is called a <u>watershed.
</u>
b) Pollution from a single, identifiable source is called <u>point source pollution</u>.
c) Pollution which is very difficult to link to a particular origin is called <u>non-point source pollution.
</u>
<u>Explanation:</u>
- A watershed serves as a feeder to the rivers in a particular river system.
- When a certain type of pollution has a single point of origin, it is called 'point' source pollution.
- When a certain type of pollution "cannot be traced back" to a single origin and is recognized to have multiple sources, it is known as 'non-point' source pollution.
