What are abiotic factors in the photic zone?
The abiotic factors that affect the photic zone are availability of light and depth of the photic zone, temperature, stratification, salinity, nutrients, and currents and tides.
How do abiotic factors affect 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.
What are two abiotic factors that affect organisms in a stream?
Abiotic factors are the nonliving components that form the environment in which the organisms subsist in a stream (freshwater ecosystem). These include factors such as light, current, temperature, substrate and chemical composition.
What Zone has the highest productivity and biodiversity in the ocean?
the neritic zone
When the water is relatively clear, photosynthesis can occur in the neritic zone. The water contains silt and is well-oxygenated, low in pressure, and stable in temperature. These factors all contribute to the neritic zone having the highest productivity and biodiversity of the ocean.
Which oceanic zone includes the photic zone?
pelagic realm
The benthic zone extends along the ocean bottom from the shoreline to the deepest parts of the ocean floor. Within the pelagic realm is the photic zone, which is the portion of the ocean that light can penetrate (approximately 200 m or 650 ft).
What are the differences in the abiotic factors of the open ocean photic zone compared to the open ocean photic zone?
The difference is about the primary production and the oxygen concentration and so the pH of the water. In the aphotic zone, there is no light, so vegetal organism can’t grow and realize the photosynthesis, the CO2 is accumulated, there is less Oxygen and the pH is lower than in the photic zone.
How do abiotic and biotic factors work together in the ocean?
The biosphere includes biotic factors such as living plants and animals it also includes abiotic (non-living) factors such as soil, water, temperature, light and salinity. The abiotic factors help the ocean to work. Phytoplankton which is the base of the food chain need light, nutrients and CO2 to photosynthesize.
How biotic and abiotic factors that make up the stream ecosystem function together?
In general, abiotic factors like rock, soil, and water interact with biotic factors in the form of providing nutrients. The water, phosphorus, nitrogen, and carbon cycles are examples of this. Another way biotic and abiotic factors interact is that biotic factors often change the geology and geography of an area.
What is the limiting factor responsible for the low productivity of the open ocean in the saltwater biome?
However, in open oceans nutrients are often in short supply. They are an important limiting factor for productivity in aquatic life zones. Phosphorus is the main limiting nutrient in freshwater life zones, whereas nitrogen is the main limiting nutrient in saltwater life zones.
Which conditions in the ocean promote high productivity?
The proximity to land and its nutrient sources, the interception of sinking organic matter by the shallow seafloor, and the propensity for coastal upwelling all result in highly productive ecosystems.
What are the biotic and abiotic 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.
What factors affect the productivity of ocean primary productivity?
Abiotic factors like solar radiation and nutrients, and biotic factors like zooplankton predation may affect ocean primary productivity. Productivity varies with the season, and also locally and globally.
How do non-living abiotic factors affect an ecosystem?
The non-living abiotic factors control which organisms live in an ecosystem, where they live and how many of them are there. Even slight changes in abiotic factors can have a significant effect on organisms in and ecosystem.
Why is ocean life not evenly distributed?
Due to interactions of abiotic factors such as salinity, temperature, oxygen, pH, light, nutrients, pressure, substrate and circulation, ocean life is not evenly distributed temporally or spatially, i.e., it is “patchy”.
