What is ecological balance and measure to prevent it? |
| Answer» Ecological balance is a state of dynamic equilibrium within\xa0a community of organisms in a habitat or ecosystem. It can happen when the diversity of living organisms remains relatively stable. Gradual changes do take place but that happens only through natural succession. It can also be explained as a stable balance in the numbers of each species in an ecosystem. This occurs through competition and cooperation between different organism s where the population remains stable. This balance is brought about by the fact that certain species compete with one another determined by the environment in which they grow. This balance is also attained by the fact that some species depend on others for their food and sustenance. Such accounts are encountered in vast grasslands\xa0where the herbivorous\xa0animals (deer, zebras, buffaloes, etc.) are found in plenty.\xa0Ecological balance may be disturbed\xa0due to the introduction of new species,\xa0natural hazards or human causes.\xa0Human interference has affected the\xa0balance of plant communities leading\xa0to disturbances in the ecosystems. Such\xa0disturbances bring about numerous\xa0secondary successions. Human pressure\xa0on the earth’s resources has put a heavy\xa0toll on the ecosystem. This has destroyed its originality and has caused adverse\xa0effects to the general environment.\xa0Ecological imbalances have brought\xa0many natural calamities like floods,\xa0landslides, diseases, erratic climatic\xa0occurrences, etc. There is a very close\xa0relationship between the plant and\xa0animal communities within particular\xa0habitats. Diversity of life in a particular\xa0area can be employed as an indicator of\xa0the habitat factor. Proper knowledge\xa0and understanding\xa0of such factors\xa0provide a strong base for protecting and\xa0conserving the ecosystems. | |
