kirill [66]

The biodiversity will decrease due to an increase in pollution is the effect will have on the biodiversity on the river ecosystem.

Biodiversity is the actual collection of total amounts of flora and fauna present in a particular ecosystem. The river ecosystem consists of the aquatic plants, the aquatic animals like fishes,etc and even the surrounding land plants and animals, who utilize the river water for their living.

The inclusion of the polluted sewage of the surrounding area into the river directly mixes several chemicals to the water, which are potentially harmful for all the animals living there.

Aloiza [94]

3 peaks

Explanation:

Topographic map is used to show different landforms using different symbols. There are two important elements of landforms that include elevation and slope. It uses contour lines to portray different features of lands on the map such as slope and elevation.

<em>According to topographic maps, more close are the counter lines, more elevation are in the landforms. </em>

Peak is the pointed top of mountains. In this topographic maps peaks or elevation is shown in the form of irregular spherical shape. There are 4 elevations in the map but only 3 shows the peak according to counter line formation and the fourth elevation will not have peak on the top.

Hence, the given topographic map has only 3 peaks in the landform.
