Question

Find out in the past if these were some biotic and abiotic factors in the ecosystems you have selected. But now they are not found. If this is the situation, find out the reasons for their diminution.

Answer 1

Change is a fundamental factor in determining whether a plant or animal species survives, moves out of an environment or goes extinct. Changes come in the form of both abiotic and biotic factors. Abiotic factors include all non-living items within an ecosystem, such as temperature and rainfall. Biotic factors are all the living organisms within an ecosystem. Unfavourable abiotic or biotic factors may have dire consequences for a species. There were some biotic and abiotic factors found in the past but they are not existing now because they were unable to evolute according to the changed surroundings.
