Detailed explanation-1: -In a pond, which of the following changes would most likely result in terrestrial succession? An increase in water plants growing in the pond.
Detailed explanation-2: -The lifespan of a pond is determined by how fast it “fills in.” The natural succession is for a pond to turn into a bog, then a bog into a field, then a field into a forest. However, with proper maintenance, the pond will remain a pond as long as possible.
Detailed explanation-3: -The rate of succession will be faster in a forest destroyed by fire because here some soil or sediment is present leading to secondary succession while in a newly created pond the succession is primary, therefore, it is slow.
Detailed explanation-4: -Autogenic succession can be brought by changes in the soil caused by the organisms there. These changes include accumulation of organic matter in litter or humic layer, alteration of soil nutrients, or change in the pH of soil due to the plants growing there.
Detailed explanation-5: -In terrestrial ecosystems, succession can occur as either primary or secondary succession. Primary ecological succession is the type of succession that occurs when an area experiences a disturbance that is so severe that none of the original species survive and the ecosystem must rebuild from bare rock.
