Detailed explanation-1: -Ecological succession is the process by which natural communities replace (or “succeed”) one another over time.
Detailed explanation-2: -The trees do not replace grasses as they require more water than grasses and this would lead to water scarcity for other species. Also, trees are prone to catch fire and the fire spreads swiftly. Due to these reasons, trees do not replace the grasses as a part of ecological succession.
Detailed explanation-3: -The change in an ecosystem that happens when one community replaces another as a result of changing abiotic and biotic factors is ecological succession.
Detailed explanation-4: -Secondary Succession This type of succession is faster because the soil is already in place. In this case, the pioneer species are plants such as grasses, birch trees, and fireweed. Organic matter from the pioneer species improves the soil.
