What is one difference between primary and secondary succession? Primary succession can start from bare rock; secondary successi
on starts from organic soils. Primary succession occurs in habitats with rich organic soil; secondary succession does not. Primary succession is always caused by human disturbances; secondary succession is not. Trees are often the first colonizing species in primary succession, but trees are never the first species in secondary succession.
Primary succession can start from bare rock; secondary succession starts from organic soils.
Explanation:
Primary succession is when the growth of pioneer species rake place in an bare and new environment. The secondary succession is when the growth of species take place due to the disturbances in the primary succession. The secondary succession is based on fire, floods, or any man-made disturbances in the region.
Protons have a positive charge. The number of protons in a nucleus determines the identity of the atom (element) and this number is called the atomic number.
