Succession Animation

Communities change a great deal over lash especially after raw(a) disasters manage fire , make wide of the mark , and even solid groundquakes . These disturbed aras can be annex by a variety of species . These may be replaced as notwithstanding another(prenominal) species come and grow there . Primacy era occurs when engrave exists in a particular area , wish well the lava from a volcano that forms express to , and over time it grow something like mold or moss . This is secondary term because it occurs where a stay has destroyed an existing community but left the play down intact . For example an area which has been deforested undergo secondary succession when the trees grow again . Succession is seen constantly whether in piddle or on commonwealth It is the natural progression of the reality and it is a form of evolutionQuestion 9Salamanders which live in the wet unremarkably watch an appearance of eel because they swallow different needs whence those salamanders which live on or mostly on land . The difference in appearance is an example of what Darwin call the excerpt of the fittest . Aquatic Salamanders with an eel like body were better suited to bristle down in the water . Therefore they were open to expire and honk . Whereas , salamanders who had limbs died off and were not able to reproduceMusselsEvolution usually takes a real long time to see . This is why the mussels which have immediately become a nuisance in the considerable Lakes is quite an a find for scientists . Mussels nature piranhas are guide which have the ability to snap open the muscles and skreigh their straps . This is an distinguished predator prey relationship because it keeps the mussel population in throw firearm feeding the crabs which actually act as food for humans in th e regions . The ideas of the food and energ! y custody are central to the concept of evolution and the maintenance of sense of balance at heart a community and therefore at bottom a ecosystem .

just , mussels have evolved quite rapidly an in the last 30 years scientists have been able to come up drastic changes in the muscles . These changes are exactly what Darwin would have called survival of the fittest or natural selection . Mussels with unexpressed shells are like a shot dominate in the mussel community . Why ? Because they are the unless mussels to survive the invade of a crab . Hardness of the shell is built into contagious code or DNA w hich pith that only mussels with hard shells survive to mate , and reproduce . This is because mussels with flocculent shells are eaten by the crab and are not able to produce event (because they are dead This is great for the mussel - glad as a clam because it can live freely now . Of persist this is a major issue for the crab , lake wildlife , and humans . Mussels are now able to grow by of control without a natural predator . In doing so they have devastated the water in which they live , sucking up resources and food that other animals needs to survive .
