Mangrove Day 1

What is an Ecotone

• A homogeneous area dominated by a single ecosystem.

• A boundary where two ecosystems meet and integrate

• A specialized habitat that supports only endemic species

• A region with uniform climatic and soil characteristics.

Porous tissue present on aerial roots of Mangroves which helps in gaseous exchange

Which of the following is not a characterstic of Mangrove ecosystem

• High Salinity

• Waterlogged Soils

• Low Oxygen

• Nutrient rich soil

Which of the following is not a characterstic of Mangrove roots

• Presence of root hairs

• Narrow casparian strips

• Exarch Protoxylem

• Longer elongation zone

Mangroves are found in

• Temperate region

• Tropical region

• Subtropical region

• Aquatic region

Which on the following belongs to Pneumatophores

• Heart roots

• Cone roots

• Stilt roots

• Pencil roots

Mangroves is an example of

• Divergent Evolution

• Convergent Evolution

• Adaptive evolution

• Parallel evolution

Salt tolerant species are also known as

Why are aerial roots present in mangroves?

• To provide structural support in strong winds and waves.

• To facilitate gas exchange in oxygen-deficient soil.

• To absorb nutrients directly from saline water.

• To store excess water during low tide.

Why are mangrove ecosystems considered dynamic?

• They are limited to stable and uniform soil conditions.

• They remain unaffected by tidal fluctuations and salinity changes.

• They experience constant interaction between terrestrial and marine environments.

• They have a fixed biodiversity and unchanging ecological roles.
