There are many different types of ecosystems. Climate conditions determine which ecosystems are found in a particular location. A biome encompasses all of the ecosystems that have similar climate and organisms.

Answer 2

HEY DEAR,  HERE IS YOUR ANSWER.....  An undisturbed eco system has an environment that is conducive to the life forms.. there is a biotic balance.. a mutual inter dependence and harmony in it..  Any thoughtless invasion into its domain for undue exploitation of its resources would tilt the natural balance adversely and pave way for environmental and biotic imbalance of sorts..  I shall illustrate with an example. The farmers used to control the pests on field crops by spraying chemicals.. There are natural enemies of pests in the ecosystem which help to keep the pest:predator ratio at a certain level, in the normal course.. When the farmer kills the pests en masse through chemical spray, the predators that live on the pests, die of starvation.. And when the new flush of pests hatched by escaped pests or the escaped eggs (not touched by chemical adequately to have it killed) are hatched, there is no adequate predators to keep the natural check (as they have also died in large number).. Without the natural control in operation, pests out number and cause great damage to crops.. Sometimes they develop resistance to pesticide and are not killed easily by repeat sprays.. Thus nature asserts its right for survival and we have to give up our aggressive strategies to fall in line with the nature's choice.. Now farmers have learnt to preserve the predators (also called defenders) and have the pests controlled..  I hope the position is somewhat clear.. But the way the nature preserves a favourable environment for the sake of the life forms is complex and a subject of great promise, interest and continuous revelation to researchers...  HOPE IT HELPS YOU.. &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& THANKS..  MARK ME BRAINLIEST PLZ IF ITS HELPFUL....  :)
