How do living things biotic factors interact in intertidal zones and estuaries ecosystem?

How do living things biotic interact in intertidal zones and estuaries ecosystem?

Estuaries and intertidal zones make up an ecosystem. Living things in these environments interact with each other. They exhibit feeding relationships that enable the nutrients and energy to cycle through them. Human lives depend to some extent on the abundant resources of estuaries.

How do abiotic factor affect the estuaries and intertidal zones?


Abiotic factors include the water temperature, amount of sunlight, soil composition, and dominate geographical features. Water Temperature: Since intertidal zones are all around the world, their climates change drastically, thus changing the temperature of the water.

What are the biotic factors of the intertidal zone?

Intertidal Zone Biotic Factors: Human Impact, Density of Algae/Kelp, Population of: Plants, Mollusks, Crustaceans, Worms, Fish, and Mammals. Intertidal Zone Abiotic Factors: Water Depth, Temperature, Turbulence, Salinity, Ph Balance, Tides, Winds, and Sediment.

Why are estuaries and intertidal zones important to living and nonliving things?

Estuaries provide vital environmental functions and values. … act as breeding places and nurseries for many estuary and marine species. provide essential ecosystem services such as food provision, carbon storage, filtering nutrients and sediment in runoff from the surrounding catchment area and storm protection.

How do living and nonliving things interact in estuaries and intertidal zones?

The estuary is an ecosystem – a group of living and non-living things interacting with each other. … The organisms within the estuaries, as with all ecosystems, are constantly competing, preying and/or co-operating with others to survive.

How do living and nonliving things interact in an intertidal zone?

Intertidal zones of rocky shorelines host sea stars, snails, seaweed, algae, and crabs. Barnacles, mussels, and kelps can survive in this environment by anchoring themselves to the rocks. … Organisms that cannot normally survive low tide conditions, like sea stars, shrimp, or fish, can take refuge in these pools.

What factors affect estuaries?

Common threats to estuaries

  • increased nutrients and algal blooms.
  • loss of habitat and biodiversity.
  • contaminants and pollutants.
  • accelerated rates of sedimentation.
  • disturbance of acid sulfate soils.
  • changes to freshwater and tidal flows.
  • invasive species.
  • climate change.

Why is important to monitor biotic factors in estuarine environments?

Why is it important to monitor abiotic factors in estuarine environments? Answer: It is important to monitor parameters such as pH, temperature, salinity, and DO because each of these factors must re- main within a certain range to ensure the survival of species living in the estuary.

What are the abiotic and biotic factors in intertidal zone?

c. Abiotic factors of intertidal zones include the water temperature, amount of sunlight, soil composition, and dominate geographical features like the size and type of rocks.

Why are estuaries and intertidal zones important to humans?

Importance of estuaries

Estuaries are very important to the lives of many animal species. … Estuaries filter out sediments and pollutants from rivers and streams before they flow into the ocean, providing cleaner waters for humans and marine life.

Why are intertidal zones and estuaries important?

The intertidal or littoral zone maintains a balance between the land and the sea. It provides a home to specially adapted marine plants and animals. Those organisms, in turn, serve as food for many other animals. The intertidal zone also staves off erosion caused by storms.

What are some abiotic and biotic factors in the ocean?

Biotic factors include plants, animals, fungi, algae, and bacteria. Abiotic factors include sunlight, temperature, moisture, wind or water currents, soil type, and nutrient availability. Ocean ecosystems are impacted by abiotic factors in ways that may be different from terrestrial ecosystems.

Why are organisms that live in the intertidal zone adaptable?

As the tides rise and fall, the salinity (salt concentration) constantly changes. Animals living in the intertidal zone must be able to tolerate wide salinity variations. If sufficient nutrients are available, intertidal animals reproduce rapidly, so they constantly compete for space, light, and food.

How will climate change affect estuaries?

Climate changes including rising sea levels, altered rain patterns, drought, and ocean acidification threaten to degrade estuaries. Rising sea levels will move ocean and estuarine shorelines by inundating lowlands, displacing wetlands, and altering the tidal range in rivers and bays.
