The main kinds of organisms in aquatic ecosystems are free-floating, very small organisms called plankton, strongly swimming organisms called nekton, bottom-dwelling organisms called benthos and decomposers, such as bacteria.
People also ask, what 5 factors determine the types and numbers of aquatic organisms found in the layers of aquatic life zones?
In aquatic systems, the key factors determining the types and numbers of organisms are temperature, dissolved oxygen, sunlight availability, and nutrient availability.
- The producers in this ecosystem are planktonic algae.
- The primary consumers include such animals as microscopic crustaceans and rotifers – the so-called zooplankton.
- The secondary (and higher) consumers are swimming insects and fish. These nekton usually move freely between the littoral and limnetic zones.
Subsequently, what are aquatic life zones definition apes?
aquatic life zones that include lakes, rivers, streams, and inland wetlands. plankton. are any drifting organisms (animals, plants, archaea, or bacteria) that inhabit the pelagic zone of oceans, seas, or bodies of fresh water.
What are the four life zones?
Explanation: The epipelagic zone, mesopelagic zone, bathypelagic zone, abyssopelagic zone, and the hadalpelagic zone are the major marine life zones. Each zone is characterized by depth, with the hadalpelagic zone being the deepest.
What are the zones under horizontal ocean zone?
The ocean is divided into horizontal zones based on the depth of water beneath: the intertidal, neritic, and oceanic.
What are the zones under vertical ocean zone?
The vertical zones in the ocean include the epipelagic, mesopelagic and bathypelagic zones. The zones are based on the amount of light that penetrates the ocean waters. The epipelagic zone is also called the sunlit zone because it receives enough sunlight to support photosynthesis.
What are three major life zones of the ocean?
Explanation: The epipelagic zone, mesopelagic zone, bathypelagic zone, abyssopelagic zone, and the hadalpelagic zone are the major marine life zones. Each zone is characterized by depth, with the hadalpelagic zone being the deepest.
What four life zones are found in deep lakes?
The zones discussed are the Littoral Zone, Limnetic Zone, Profundal Zone, Euphotic Zone, and Benthic Zone.
What major ecosystem and economic services are provided by marine systems What are the three major life zones in an ocean?
Aquatic systems are enormous reservoirs of biodiversity: different ecosystems, species, genes, and biological and chemical processes. What are the three major life zones in an ocean? Coastal zone, intertidal zone,open sea.
What plants and animals live in the aquatic?
Seaweeds, algae, snails, crabs, small fishes, mollusks, worms, clams, and crustaceans live in the coastal area. The pelagic zone consists of open ocean farther from the land and contains surface seaweeds, fish, whales, and dolphins.
Which of the following are examples of aquatic ecosystem services?
Aquatic ecosystems (rivers, lakes, groundwater coastal waters, seas) support the delivery of crucial ecosystem services, such as fish production, water provisioning and recreation.
