What is the similarity between primary and secondary succession?

Answer 1

Primary succession occurs on land that is new and has never had a flora and fauna example: glacier retreats, lava flows. Secondary succession occurs on land that has been cleared example: by fire, of flora and fauna, but which still has viable seeds and spores in the soil.

Answer 2

They both taking along time period to form the forest back.

Primary approximately thousands of year because they started from an empty land.

Secondary approximately only take hundreds of years because they started from forest that have been destroyed by natural disaster, burning, or whatever reason that destroyed the forest but it still has some soil.

Answer 3

Similarity;

Both part of succession.

Difference;

Primary-

• nothing there before
• happens after volcanic eruption
• occurs when there is no good nutrient-filled soil
• slower than secondary succession; gradual
• needs pioneer species (look this up either in a dictionary or wikipedia.com)

Secondary;

• occurs after an ecological disturbances and disruption
• happens after forest fires, tsunamis, floods, harvesting, and hurricanes
• faster than primary succession
• no need for pioneer species
• reforestration happens sometimes

Bold=look up in dictionary or, as highly recommended, Wikipedia.com

Answer 4

the result of primary succsion would be that something like a forest start to grow in a place it didnt exsist before like in a barren land whilst a secondary would that something would stat to grow after it was primarly destroyed ex: a forest fire happens a few weeks later or even years another grows either naturally or someone plants it hope it helped ;))

Answer 5

Primary comes from nothing and secondary comes from a previous community.
