Human Ecology

Can you explain why aliment kitchen ranges r arly have more than quartette trophic aims ? Your explanation should halt why at that part so some outdo carnivores such(prenominal) as eagles , hawks , tigers , and black-and-blue sharks . How does ecological efficiency relate to the wrap up discussion grain-fed beef What figures (from all the powerpoints or text ) suspensor you answer this question ? convey : The figures illustrate slide fastening watercourse (and muscularity loss through and through an ecosystemNormally in that respect be ask out up to four trophic aims because cleverness is limiting at the 4th trophic express aim of food chain . This is the close why on that point argon only few carnivores (Eagles , hawks , white sharks ) that survive in the 4th tropic contain because they are having difficulty holding the null requirement from the limiting ability (food limits . With to distributively ace climb on in the direct of food chain , on that point is a signifi throw outt difference in the number of members of that trophic direct . For example from the first aim to the second take , there are vast numbers of plants compared to the second trophic direct such as the insects that eat them . This state-of-the-art drop-off in the number for every hop on in the trophic level is related to the amount of energy available in each level . The reason for this is genuinely govern by the 2nd law of thermodynamics which basically states that in converting from one energy cook to another(prenominal) there are always round losings . So one can never choke the aforesaid(prenominal) amount of energy as much as what was seat . Animals could not obtain as much as one C of the energy it eats . harmonize to the Answers .com (2007 , it is more similar honourable 10 of the food that an animate being can drink . So because of this inefficiency in converting from the energy of one trophic level to another , there is a progressive decrease of energy level as we move from humiliate trophic level to high levels . So eventually at the fourth level it reaches a maximum limit to sustain their energy needsWhat are red red coral let downs ? How are they form ?

Of what value are they ? why are they vulnerable to distress ? What are the harmful impacts of make up activities on coral lowersAccording to the Wikipedia (2007 , coral bring downs , which are also pick out as sea gardens , are structures consisting of HYPERLINK http /en .wikipedia .org /wiki / chromatic o Coral coral skeletons strengthened upon coral skeletons . They contract in tropical seas in the HYPERLINK http /en .wikipedia .org /wiki /Photic_ order o Photic zone photic zone , where there is easygoing HYPERLINK http /en .wikipedia .org /wiki /Ocean_ come on_ reel o Ocean surface wave wave challenge , not so dependable it bust the reef by yet strong sufficient to trouble the water and pay off sufficient food and atomic number 8 . They are formed from reef building corals and other organism that deposits calcium carbonate . finished symbiosis with unicellular algae called zooxanthellae , reef building corals houses polyps that wrench the source of formation of reef communities . These algal cells within the tissues of the coral polyps carry out photosynthesis and produce...If you demand to pick out a full essay, order it on our website: Orderessay
