Growing Root Classes

Hierarchy of molecular organisation  All biomolecules derived from very simple low-molecular-weight precursor like CO2,H2O, atmospheric nitrogen.... Organisms convert these precursor to complex building block biomolecules through a series of metabolic intermediates of progressively increasing molecular size and complexity. They link covalently to make micro molecules such as amino acids to proteins monosaccharides to polysaccharides... Soon this high molecular weight macromolecules assembles with each other to form supramolecular complexes such as lipoproteins(lipid + proteins ) glycoproteins (sugar+proteins )glycolipids (sugar + lipids)..  These are not bonded with covalent bonding they stick together through week non-covalent forces like hydrogen bonding ionic bonding hydrophobic interactions Van der Waals force of interaction, these bondings are stable and very specific. Soon this supramolecular complexes are further assembles into cell organelles such as nucleus mitocho

INTRODUCTION Biotic components of an ecosystem are the following  #producers/autotrophs #consumers/heterotrophs #decomposers #Transformers/converters PRODUCERS *  Energy fixation and organic matter productions - producers fixing the solar energy with carbon dioxide and water does it produce organic matter such as carbohydrates, proteins, lipids etc.. * Incorporation of minerals into protoplasm - plants can absorb nitrogen phosphates iron magnesium... From soil or water and incorporate with into their protoplasm. *Serves as a source of energy for heterotrophs - the energy and the food stored by the producers/ plants are taken or consumed by heterotrophs, in that way the heterotrophs get nourished. * Provide habitat - plants provide suitable habitat for environment for many other organisms. * Environmental modification - aisi no some autotrophs are involved in the weathering of Rock ( formation of soil from rock ) , modification of climate by breaking the wind. HETEROTROPHS *
