  RELATIONSHIP BETWEEN MICROORGANISMS AND ATMOSPHERE      AEROMICROBIOLOGY ·        Aeromicrobiology is the study of living microorganisms which are suspended in the air. These microbes are referred to as Bioaerosols. BIOAEROSOLS ·        Bioaerosols are a sub-category of particles released from Terrestrial and Marine ecosystems into the Atmosphere. ·        Charles Darwin was the first to observe the transport of dust particles but Louis Pasteur was the first to research microbes and their activity within the air. ·        Bioaerosols include Bacteria, Fungi, Viruses and Pollen. ATMOSPHERE ·        The Atmosphere of earth is the layer of Gases, commonly known as Air that surrounds the planet earth and is retained by Earth's ...

  ORGANIZATION OF BIOSPHERE   BIOSPHERE ·        The Biosphere (also known as the Ecosphere), is the worldwide sum of all Ecosystems. ·        The Biosphere is made up of the parts of Earth where life exists. ·        Scientists describe the Earth in terms of Spheres. a)      Lithosphere or Geosphere - The solid surface layer of the Earth. b)      Atmosphere - The layer of air that stretches above the Lithosphere. c)      Hydrosphere - The earth’s water, on the surface, in the ground, and in the air. d)      Cryosphere – The portions of Earth's surface where water is in solid form, including sea ice, lake ice, river ice, snow cover, glaciers, ice caps, ice sheets, and frozen ground. Thus, there is a wide overlap with the Hydrosphere.   ...
