Description of Ecosystem

An ecosystem is a community of living organisms (plants, animals and microbes) in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.[2] These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows.[3] As ecosystems are defined by the network of interactions among organisms, and between organisms and […]

Biotic component

Biotic components are the living things that shape an ecosystem. A biotic factor is any living component that affects another organism, including animalsthat consume the organism in question, and the living food that the organism consumes. Each biotic factor needs energy to do work and food for proper growth. Biotic factors include human influence. Biotic components are contrasted to abiotic components, which are non-living […]

Abiotic Component

In ecology and biology, abiotic components (also called abiotic factors) are non-living chemical and physical factors in the environment, which affect ecosystems. Abiotic phenomena underlies all biology. In biology, abiotic factors can be classified as radiation (light), temperature, water, atmospheric gases, or soil. The macroscopic climate often influences each of the above. Pressure and sound waves may also be considered in the context of marine or sub-terrestrial environments.[1] All of these factors affect different organisms to different extents. If there is […]

Water Quality Parameters for Freshwater Fish

Fish Culture: The following water quality parameters are typically of highest importance to freshwater fish being raised under aquaculture conditions: Water temperature, which is measured in units of degrees Farenheight (oF) or Centigrade (oC). Dissolved oxygen (DO) is the amount of oxygen (O2) dissolved in water and is measured in units of percent saturation or […]

Principles of Aquaponics

Aquaponics is the symbiotic cultivation of fish and plants in a re-circulating water system. The word “aquaponics” is a combination of the words aquaculture and hydroponics. Aquaponics systems can be as small as a household fish tank, or as large as a football field. In all cases, the principles of aquaponics are the same: Humans feed fish. Fish excrete waste into water. […]

Properties of Water

Water is the only substance on Earth that exists naturally in three states–solid, liquid, and gas.  Water is made of oxygen and hydrogen.  The way these elements come together or bond creates a molecule, H2O, with unique properties.  Water can stick to itself; it is cohesive.  This allows water to flow and go thru plants or pipes.  Water is […]

Oxygen

From Wikipedia: Oxygen is a chemical elementwith symbol O and atomic number 8. Its name derives from the Greek roots ὀξύς (oxys) (“acid”, literally “sharp”, referring to the sour taste ofacids) and -γόνος (-gοnos) (“producer”, literally “begetter”), because at the time of naming, it was mistakenly thought that all acids required oxygen in their composition. At standard temperature and pressure, two atoms of the element bind to form […]
