Question

question 1 - 18
what is the likely impact of increased turbidity on a pond ecosystem?
decreased plant growth due to limited light
improved light perception and photosynthesis
increased oxygen availability
increased diversity of species

Explanation:

Increased turbidity in a pond ecosystem reduces light penetration, which in turn decreases the rate of photosynthesis in plants, leading to decreased plant growth. Improved light perception and photosynthesis are incorrect as turbidity blocks light. Turbidity doesn't directly increase oxygen availability and usually leads to a decrease in species diversity due to habitat - change and reduced light for primary producers.

Answer:

Decreased plant growth due to limited light
