Marine Science 1- Chapter 13/14 Flashcard

Front

What is vertical zonation in intertidal zones?

Back

Vertical zonation refers to the distinct bands of organisms that are arranged in layers at different heights in the intertidal zone, influenced by factors such as tidal action and exposure to air.

Front

What type of producers are benthic diatoms?

Back

Benthic diatoms are microscopic algae that live on the bottom of aquatic environments, particularly in mudflats, and are key primary producers in these ecosystems.

Front

How do mangroves adapt to high salinity?

Back

Mangroves adapt to salty environments by developing salt glands that excrete excess salt, allowing them to thrive in coastal areas.

Front

What is the function of osmoregulators in marine organisms?

Back

Osmoregulators are organisms that maintain their internal water balance by actively transporting salts and water through their gills and kidneys.

Front

What role do bioturbators play in mudflat ecosystems?

Back

Bioturbators are organisms that disturb and mix the sediment in mudflats, which helps aerate the soil and promote nutrient cycling.

Front

Define phytoplankton and their role in marine ecosystems.

Back

Phytoplankton are microscopic plants that float in water and are primary producers, forming the base of the marine food web.

Front

What is the significance of mudflats in coastal ecosystems?

Back

Mudflats provide critical habitat for various species, serve as feeding grounds for birds, and play a role in nutrient cycling and sediment stabilization.

Front

Explain the concept of salinity and its impact on marine life.

Back

Salinity is the concentration of salts in water, which affects the osmoregulation of marine organisms and influences species distribution.

Front

What adaptations do organisms in intertidal zones have for survival?

Back

Organisms in intertidal zones have adaptations such as strong attachment mechanisms, ability to tolerate desiccation, and specialized feeding strategies to survive fluctuating conditions.

Front

Describe the process of bioturbation.

Back

Bioturbation is the reworking of soils and sediments by animals, which can enhance nutrient availability and influence the physical structure of the habitat.
