Detailed explanation-1: -Succession will cease in an ecosystem when what occurs? Animals begin to use plant resources.
Detailed explanation-2: -Ecological succession is the process by which the mix of species and habitat in an area changes over time. Gradually, these communities replace one another until a “climax community”-like a mature forest-is reached, or until a disturbance, like a fire, occurs. Ecological succession is a fundamental concept in ecology.
Detailed explanation-3: -The main causes of ecological succession include the biotic and climatic factors that can destroy the populations of an area. Wind, fire, soil erosion and natural disasters include climatic factors.
Detailed explanation-4: -Climax. The last stage of ecological succession is the formation of a climax community. There is minimal resource competition and no further replacement of dominant plant species.
Detailed explanation-5: -Succession is the change in either species composition, structure, or architecture of vegetation through time. Vegetation has three important aspects that are subject to change. Species composition includes the roster of the species. There can be many or few species in vegetation.
