    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.

        value: measurement value
    description: Elevation of the sampling site is its height above a fixed reference
      point, most commonly the mean sea level. Elevation is mainly used when referring
      to points on the earth's surface, while altitude is used for points above the
      surface, such as an aircraft in flight or a spacecraft in orbit.
    title: elevation, meters
    comments:
    - All elevations must be reported in meters. Provide the numerical portion only.
    - Please use https://www.advancedconverter.com/map-tools/find-altitude-by-coordinates,
      if needed, to help estimate the elevation based on latitude and longitude coordinates.

      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.

      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.

    - All elevations must be reported in meters. Provide the numerical portion only.

    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.
