Answer:
The answer is: option I, II and III (i.e I. increasing the turbidity and cloudiness of the water.II. reducing sunlight penetration and thereby decreasing productivity of aquatic plants. and, III. clogging gills of fish and bottom dwellers.
Explanation:
Activities such as road construction, building construction, logging, remove the protective vegetative covering from soils. As a natural part of the ecosystem, and, formed by the most common mineral that is found on or near the surface of the Earth, Sediments classified by origin are of four types: cosmogenous, hydrogenous, lithogenous and biogenous. Sediment is fine-grained particles like silt and clay that is broken down by processes of weathering and erosion. Wind, force of gravity acting on the particles, water and ice help carry these particles to rivers, lakes and streams.
Sediment increases the potential for flooding. Loose sediments are washed into the streams with surface water runoff during rain storms
Some of the ways sediment pollution affects the waterways is by:
- Making the water cloudy, thereby preventing visibility in water. Even, animals in the water are prevented from seeing food.
- Sediment can clog fish gills, affecting fish egg and larvae development.
- High levels of turbidity limit penetration of sunlight into the water, thereby depriving the aquatic plants from sunlight needed for optimum productivity.
