Question
1, In what kind of micro environments would we find bacteria and archaea?(I think this is a trick question? Int it that Bacteria and Archaea can be found in all sorts of environments even ones that we would think impossible or to extreme for the survival of life? For example around hydro thermal vents in the ocean? Or in the most coldest of places? Or is there a specific "micro environment" required for bacteria and archaea to survive?)
2. What are the unique characteristics of fungi? Why are they important?
3.Why are there so many animals?
(This also seems very broad of a question to me. I want to say that there are so many different animals because of evolution and the adaptation of organisms over a wide variety of different environments, but at the same time I'm not sure if that is a good enough explanation for such a big question. I guess I'm just looking for the best way to explain this and I'm not sure if my explanations are enough. What am I missing?)
Explanation / Answer
1. Bacteria are found everywhere and anywhere on earth. They have no specific microenvironment to survive. They are found in all types of environments, conditions and habitats. Whereas the Archea were seen as extremophiles that lived in harsh environments (hot springs, salt lakes, soils, oceans, marshlands and the human colon). For example: - Acidophiles (found in sulfur rich environments), Thermophiles (found in extremely high temperatures) etc. Archea are found in large numbers, particularly in oceans. ------------------------------------------------------------------------- 2. Unique characteristics of fungi: - i) Cell wall: - Cell wall is rigid and contain chitin. ii) Cell type: - Mostly multicellular and filamentous in nature. The filaments are called hyphae. A limp of hyphae consitutes the mycelium. iii) Nutrition: - They are heterotrophic and depend on other organisms (either dead or living) for food. Many parasitic fungi possess special food absobing structures called Haustoria or modified hypae. iv) Reproduction: - Asexual and sexual reproduction is common. Both sexual (meiotic) and asexual (mitotic) spores may be produced, depending on the species and conditions. Importance of fungi: - i) They decompose dead organism and releasw their nutrients for reuse by the living. ii) They live in a mutually beneficial symbiotic relationship with another organisms (often a plant), giving more-efficient mineral uptake and sugar translocation to the root by the plant. iii) They are helpful in production of alcoholic beverages (like beer and wine) through fermentation of sugars to ethanol and carbon dioxide. Example: -Saccharomyces cerevisiae - a budding yeast. iv) They are useful in commercial production of some vitamins. v) They are useful in baking (baker's yeast). --------------------------------------------------------------------------------- 3. There are so many animals because they have sufficient food, suitable surrounding environment and diversified habitats, depending on the species. Living things cannot surivive without a suitable environment condition, food and habitat. If these are lacking, species want to adaptate or migrate or involve in evolution. So, it would be the main reason for increased population in any living species. iv) They are useful in commercial production of some vitamins. v) They are useful in baking (baker's yeast). --------------------------------------------------------------------------------- 3.
