5.0 AQUATIC AND MOSQUITO EXAMINATION
TEST 2026 FULL QUESTIONS AND CORRECT
ANSWERS
◉How can excessive plant growth adversely affect the ecology and uses
of a water body? Answer: Prevent recreational water uses, impart tastes
or odors to drinking water, hamper water treatment operations, adversely
affect aesthetics, resort trade, and waterfront property values, produce
toxins, and harm ecology
◉What are the growth habits of Emergent aquatic plants? Answer:
Rooted plants with most of their growth extending above the water line
(i.e. cattails, rushes). Emergent aquatic plants root in shallow water or
water-saturated soils
◉What are the means of dispersal of emergent aquatic plants? Answer:
They spread via root system and can occur almost anywhere
◉What are the potential problems caused by emergent aquatic plants?
Answer: very little (excluding purple loosestrife which can quickly
outcompete native plants)
, ◉What are the growth habits of submergent aquatic plants? Answer:
Rooted plants with all (or most) of their growth occurring below the
waterline (i.e. pondweeds)
◉What are the growth habits of free-floating and rooted floating-leaved
aquatic plants? Answer: Plants whose leaves float on the water surface
(i.e. water lilies)
◉What are the growth habits of free-floating, filamentous, and "rooted"
algae? Answer: Primitive, simple plants that lack systems, leaves, and
vascular conductive system
◉What are the means of dispersal of submergent aquatic plants?
Answer: Pondweeds reproduce vegetatively (from roots); Plants with
whorled leaves when uprooted also move via wind
◉What are the means of dispersal of free-floating and rooted floating-
leaved aquatic plants? Answer: wind
◉What are the means of dispersal of free-floating, filamentous, and
"rooted" algae? Answer: wind
◉What are the potential problems caused by submergent aquatic plants?
Answer: Most pondweeds are very valuable to fish and wildlife; plants
with whorled leaves can clutter shorelines
