In aquatic ecosystems, the limiting factor for productivity is light.
What are the main limiting factors in aquatic ecosystems?
Most aquatic organisms do not have to deal with extremes of temperature or moisture. Instead, their main limiting factors are the availability of sunlight and the concentration of dissolved oxygen and nutrients in the water.
What factors affect the productivity of an aquatic ecosystem?
In aquatic ecosystems, primary productivity is driven by the availability of nutrients and light and, to a lesser extent, by temperature and other factors. Primary productivity is important because it is the process that forms the foundation of food webs in most ecosystems.
What factors limit productivity in an ecosystem?
Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input, temperature and moisture levels, carbon dioxide levels, nutrient availability, and community interactions (e.g., grazing by herbivores) 2.
What is the most significant limiting factor in ocean primary productivity?
Lack of water is the main limit on primary production on the Earth’s surface.
What are the 4 main factors that affect aquatic ecosystems?
Factors that affect aquatic ecosystems include water flow rate, salinity, acidity, oxygen, light levels, depth, and temperature.
What are 3 possible limiting factors for an aquarium ecosystem?
In the freshwater biomes, limiting factors include:
- dissolved oxygen.
Which 3 ecosystems have the highest productivity and which 3 have the lowest productivity?
The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
What two main factors determine ocean 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.
What are some factors that limit photosynthesis in the ocean?
The major limiting factors in this process are light intensity, temperature, and carbon dioxide levels. For both light intensity and temperature, if the level is too low or too high, the rate of photosynthesis declines rapidly.
