    description: Altitude is a term used to identify heights of objects such as airplanes,
      space shuttles, rockets, atmospheric balloons and heights of places such as
      atmospheric layers and clouds. It is used to measure the height of an object
      which is above the earth's surface. In this context, the altitude measurement
      is the vertical distance between the earth's surface above sea level and the
      sampled position in the air

  ecosystem:

    description: An ecosystem is a combination of a physical environment (abiotic
      factors) and all the organisms (biotic factors) that interact with this environment.
      Ecosystem is in position 1/5 in a GOLD path.
    comments:
    - The abiotic factors play a profound role on the type and composition of organisms
      in a given environment. The GOLD Ecosystem at the top of the five-level classification
      system is aimed at capturing the broader environment from which an organism
      or environmental sample is collected. The three broad groups under Ecosystem
      are Environmental, Host-associated, and Engineered. They represent samples collected
      from a natural environment or from another organism or from engineered environments
      like bioreactors respectively.

    comments:
    - The Environmental ecosystem (for example) is divided into Air, Aquatic and Terrestrial.
      Ecosystem categories for Host-associated samples can be individual hosts or
      phyla and for engineered samples it may be manipulated environments like bioreactors,
      solid waste etc.

    comments:
    - The Aquatic ecosystem category (for example) may have ecosystem types like Marine
      or Thermal springs etc. Ecosystem category Air may have Indoor air or Outdoor
      air as different Ecosystem Types. In the case of Host-associated samples, ecosystem
      type can represent Respiratory system, Digestive system, Roots etc.

    comments:
    - The abiotic factors play a profound role on the type and composition of organisms
      in a given environment. The GOLD Ecosystem at the top of the five-level classification
      system is aimed at capturing the broader environment from which an organism
      or environmental sample is collected. The three broad groups under Ecosystem
      are Environmental, Host-associated, and Engineered. They represent samples collected
      from a natural environment or from another organism or from engineered environments
      like bioreactors respectively.

      is the vertical distance between the earth's surface above sea level and the

    comments:
    - The abiotic factors play a profound role on the type and composition of organisms
      in a given environment. The GOLD Ecosystem at the top of the five-level classification
      system is aimed at capturing the broader environment from which an organism
      or environmental sample is collected. The three broad groups under Ecosystem
      are Environmental, Host-associated, and Engineered. They represent samples collected
      from a natural environment or from another organism or from engineered environments
      like bioreactors respectively.

      air as different Ecosystem Types. In the case of Host-associated samples, ecosystem
      type can represent Respiratory system, Digestive system, Roots etc.
