How does high turbidity affect aquatic ecosystems?

Question

a) Increases photosynthesis
b) Reduces light penetration, affecting photosynthesis
c) Improves oxygen levels in water
d) Has no impact on aquatic life

Answer 1

b) Reduces light penetration, affecting photosynthesis

High turbidity can decrease light penetration in water bodies, which negatively impacts photosynthetic organisms like aquatic plants and phytoplankton. This can disrupt the food chain and overall health of the aquatic ecosystem.

Answer 2

Which of the following is a potential solution to reduce turbidity in water bodies?
a) Increasing industrial activity
b) Planting vegetation along riverbanks to reduce runoff
c) Adding more nutrients to the water
d) Increasing the number of aquatic organisms

Answer 3

b) Planting vegetation along riverbanks to reduce runoff

Planting vegetation along riverbanks can help stabilize soil and reduce runoff, which in turn can decrease turbidity by minimizing the amount of sediment and contaminants entering the water body.

Answer 4

How does turbidity affect dissolved oxygen levels in water?
a) High turbidity increases dissolved oxygen.
b) High turbidity decreases dissolved oxygen by reducing light for photosynthesis.
c) Turbidity does not affect dissolved oxygen levels.
d) High turbidity improves oxygen production in water.

Answer 5

b) High turbidity decreases dissolved oxygen by reducing light for photosynthesis.

High turbidity can limit light penetration in water, which affects the ability of aquatic plants and phytoplankton to perform photosynthesis. This reduction in photosynthetic activity can lead to lower oxygen production, ultimately decreasing dissolved oxygen levels in the water.
