[Answer] How are primary and secondary succession similar and how are they different?

Answer: Primary and secondary succession both happen when plant life begins to grow again in a habitat that was once destroyed or is recovering. Secondary succession happens at an increased rate and often the plants grow thicker. An example of secondary succession is a wildfire. Primary succession happens after a habitat is completely destroyed and it finally starts to grow back but is much thinner. Plants that grow here are shrubs and bushes.

Secondary succession is one of the two types ecological succession of a plant’s life. As opposed to the first primary succession secondary succession is a process started by an event (e.g. forest fire harvesting hurricane etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species and as such secondary succession occu…

Secondary succession is one of the two types ecological succession of a plant’s life. As opposed to the first primary succession secondary succession is a process started by an event (e.g. forest fire harvesting hurricane etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil. Many factors can affect secondary succession such as trophic interaction initial composition and competition-colonization trade-offs. The factors that control the increase in abundance of a species during succession may be determined mainly by seed production and dispersal micro climate; landscape structure (habitat patch size and distance to outside seed sources); bulk density pH and soil texture (sand and clay). Simply put secondary succession is the ecological succession that occurs after the initial succession has been disrupted and some plants and animals still exist. It is usually faster than primary succession Soil is already presentSeeds roots and underground vegetative organs of plants may still survive in the soil.

Imperata Imperata grasslands are caused by human activities such as logging forest clearing for shifting cultivation agriculture and grazing and also by frequent fires. The latter is a frequent result of human interference. However when not maintained by frequent fires and human disturbances they regenerate naturally and speedily to secondary young forest. The time of succession in Imperata grassland (for example in Samboja Lestari area) Imperata cylindrica has the highest coverage but it becomes less dominant from the fourth year onwards. While Imperata decreases the percentage of shrubs and young trees clearly increases with time. In the burned plots Melastoma malabathricum Eupatorium inulaefolium Ficus sp. and Vitex pinnata. strongly increase with the age of regeneration but these species are commonly found in the secondary forest. Soil properties change during secondary succession in Imperata grassland area. The effects of secondary succession on soil are strongest in the A-horizon (0–10 cm) where an increase in carbon stock N and C/N ratio and a decrease in bulk density and pH are observed. Soil carbon stocks also increase upon secondary succession from Imperata grassland to secondary forest. • Secondary succession in Imperata -dominated grassland Oak and hickory forest A classic example of secondary succession occurs in oak and hickory forests cleared by wildfire. Wildfires will burn most vegetation and kill those animals unable to flee the area. Their nutrients however are returned to the ground …
