1. What is the primary function of a wetland ecosystem?
A. Industrial water storage
B. Flood regulation, water filtration, and habitat provision
C. Groundwater extraction
D. Urban development support
Answer: B
Rationale: Wetlands naturally regulate flooding by absorbing
excess water, filter pollutants through biological and chemical
processes, and provide critical habitat for diverse plant and
animal species.
2. Which soil type is most commonly associated with wetlands?
A. Sandy, well-drained soil
B. Rocky, impermeable soil
C. Hydric soil
, D. Volcanic soil
Answer: C
Rationale: Hydric soils are saturated long enough during the
growing season to develop anaerobic conditions, which are
characteristic of wetlands.
3. What defines a hydrophyte?
A. A drought-resistant plant
B. A salt-tolerant desert plant
C. A plant adapted to grow in water-saturated soils
D. A plant that grows only in forests
Answer: C
Rationale: Hydrophytes are plant species specifically adapted to
thrive in wet or flooded conditions.
4. Which of the following is a key indicator of a healthy wetland?
A. Low biodiversity
B. High invasive species presence
C. Diverse native plant and animal populations
D. Absence of water
Answer: C
Rationale: Healthy wetlands support diverse native species,
indicating ecological balance and proper function.
,5. What is a common cause of wetland degradation?
A. Natural tidal cycles
B. Sediment accumulation
C. Urban development and pollution
D. Seasonal rainfall
Answer: C
Rationale: Human activities such as development and pollution
disrupt wetland hydrology and ecology.
6. Which process removes excess nutrients from wetland water?
A. Evaporation
B. Denitrification
C. Photosynthesis
D. Sedimentation
Answer: B
Rationale: Denitrification converts nitrates into nitrogen gas,
reducing nutrient overload in wetlands.
7. What is the main purpose of wetland restoration?
A. Increase industrial land use
B. Return ecological functions and biodiversity
C. Eliminate all vegetation
D. Drain wetlands permanently
, Answer: B
Rationale: Restoration aims to reestablish natural hydrology,
vegetation, and ecological processes.
8. Which vegetation type is commonly found in marshes?
A. Conifer trees
B. Grasses and reeds
C. Desert shrubs
D. Alpine mosses
Answer: B
Rationale: Marshes are dominated by herbaceous plants like
grasses, sedges, and reeds.
9. What is hydrology in wetland science?
A. Study of rocks
B. Study of atmospheric pressure
C. Study of water movement and distribution
D. Study of animal behavior
Answer: C
Rationale: Hydrology examines how water flows, accumulates,
and interacts within ecosystems.
10. Which organism type is often used as a bioindicator in
wetlands?
