What is an Ecosystem?01:17

What is an Ecosystem?

Primary Production01:06

Primary Production

24.4K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

The Soil Ecosystem02:23

The Soil Ecosystem

23.6K
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

Oxygenic Photosynthesis01:26

Oxygenic Photosynthesis

438
Oxygenic photosynthesis is a fundamental process in which light energy is harnessed to drive the oxidation of water, leading to the production of molecular oxygen (O₂), adenosine triphosphate (ATP), and nicotinamide adenine dinucleotide phosphate (NADPH). This process is essential for sustaining aerobic life on Earth and is primarily carried out by cyanobacteria, algae, and plants. The core of oxygenic photosynthesis lies in the thylakoid membranes, where chlorophyll pigments facilitate...

Trophic Levels01:35

Trophic Levels

34.8K
All organisms in an ecosystem occupy a trophic level in the food chain. The lowest level consists of primary producers, which synthesize their food from either solar or chemical energy. Each subsequent level obtains energy from the levels below. Detritivores can occupy any of the levels above primary producers.

The Carbon Cycle01:14

The Carbon Cycle

42.3K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Area of Science:

  • Marine Biology
  • Ecology
  • Oceanography

Background:

  • The ocean surface is a critical habitat supporting diverse terrestrial and marine species.
  • Organisms living freely at the surface are termed neuston, including keystone species like Sargassum seaweed.
  • Neustonic communities are not uniformly distributed, forming unique ecoregions in specific ocean basins and latitudes.

Purpose of the Study:

  • To introduce the concept of neuston and their ecological significance.
  • To highlight the role of neuston in connecting various habitats.
  • To discuss the threats facing neustonic life and explore new research opportunities.

Main Methods:

  • This essay synthesizes existing knowledge on neustonic organisms and ecosystems.
  • It reviews the ecological connections and dependencies involving the ocean surface.
  • It identifies current threats, including climate change and pollution, impacting neuston.

Main Results:

  • Neuston represent a diverse group of organisms, including Sargassum, barnacles, snails, and cnidarians.
  • Many ecologically and economically important fish species depend on neuston.
  • Unique neustonic communities exist in specific oceanographic regions.

Conclusions:

  • The ocean surface ecosystem is vital for connecting disparate habitats and supporting numerous species.
  • Neuston face significant threats from climate change and pollution.
  • Further research into neustonic life is crucial for understanding and protecting marine biodiversity.
