b. It is similar but faster than primary succession
c. It begins on bare rock
d. It occurs on deforested site

Answer 1

Hint: Secondary succession is a type of ecological succession, where the plants and animals and all living organisms reorganize because of any forest fire, and natural disaster, and any lava flow, etc, where life is there but the area is changed.

Complete answer:
In case of secondary succession, where disturbance cannot take all the life and eliminate them because even though in case of fire accidents, the plants are burned, it does not mean the completely eliminated because the nutrients and all are buried on the earth and can be utilized later.

In some plants, even though they are eliminated the seeds fall on the ground, can germinate and rise again and develop into new species.
Where some species are habituated to some disturbances, for example, jackpine is usually seen in the USA and Canada where it requires heat from wildfire in order to open their cones, before the spread of seeds to the ground.

In case of some catastrophic disturbances, like volcanic eruptions and Like groceries, in these cases the biological species is completely eliminated, even though some seeds are all present they are covered with a large amount of those substances and make them separate and If it grows it has to start a new generation in that isolated area, where it can be again should be done by primary succession.

Hence, the correct answer is option (B).

Note: In some pioneer species both primary and secondary successions look similar, where these species develop slowly and they form again a new community species over many years before the climax community is established.
