Hydrothermal Vents and its Organisms! A hydrothermal vent is a fissure in a planet’s surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places‚ areas where tectonic plates are moving apart‚ ocean basins‚ an hotspots Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Common land types include hot springs‚ fumaroles and geysers. Under the sea

The range of an organism and its dispersal is limited or affected by many things in its surroundings. These things can be slightly different in their specifics from organism to organism but generally‚ for all organisms‚ these are the main restrictions to their range and dispersal (either natal or breeding). The first limiting factor to the distance they can travel from their population or parent is the resources available. One artificial barrier is habitat fragmentation by humans and their use of

important as human and animal food‚ important companions to plant roots‚ as parasites‚ and some disease producers in both plants and animals including ringworm‚ athletes foot‚ and thrush. The characteristics of fungi include that they are usually multicellular without flagella‚ they absorb food‚ they have a haploid life cycle with windblown spores during sexual and asexual reproduction. Most fungi are saprotrophs that decompose dead remains‚ a mycelium which is a mass of filaments called hyphae‚ makes

Microbial Diversity and Ubiquity Microorganisms are microscopic organisms that are so small that that they can only be visualized by the aid of a compound-brightfield microscope. While we generally cannot see individual microorganisms with the naked eye‚ they are present in virtually every habitat known to man. Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae‚ protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because

Origin of Earth and Evoluation of the Environment MODULE - 1 Environment through Ages 1 ORIGIN OF EARTH AND EVOLUTION OF THE ENVIRONMENT We live on a beautiful planet called earth‚ along with a wide variety of plants‚ animals and other organisms. Our earth‚ however‚ is part of a vast universe. The universe is about 15 to 20 billion years old. The age of the earth is approximately 4 to 5 billion years‚ while human beings evolved only around 2 million years ago. In this lesson‚ you shall learn

THE SEARCH FOR BETTER HEALTH 1.What is a healthy organism? Discuss the difficulties in defining the terms ‘health’ and ‘disease’ * Health – state of physical‚ mental and social wellbeing. It is not just absence of disease * disease – any condition which effects the functioning of any part of a living organism * difficulties in defining health and disease; * health 1) the definition of health varies with age eg stiffness in the joints is probably more common in a 90yo
