What is the main difference between primary and secondary succession?
A.) The climax of primary succession is a pine forest.
B.) Primary succession begins with bare rock.
C.) Secondary succession begins ith mosses and linches.
D.)Secondary succession includes frequent fires.
The correct answer is B. All I need to know is, WHY it is B. I'm doing corrections and it wants to know WHY it's correct. Any ideas?
Please someone help
No, I need a reason why it is correct not just something about it, to be honest, I don't even know what it's asking. That why I got it wrong, I guessed.
It still might help though let me read it.

The main difference between primary and secondary succession is that primary succession begins with bare rock, while secondary succession occurs in areas that already have soil (due to a previous disturbance such as a fire or a clearcut).
To understand why option B is the correct answer, let's examine the definitions of primary and secondary succession:
- Primary succession: This type of succession occurs in an area where no soil exists, such as on bare rock exposed after a volcanic eruption or glacial retreat. The process starts with pioneer species, such as lichens and mosses, that colonize the bare rock and begin to break it down, eventually forming soil for other plant species to grow. Over time, larger plants and trees can establish themselves, leading to the development of a climax community.
- Secondary succession: This type of succession occurs in an area that has previously been disturbed but still has some existing soil. Disturbances that can lead to secondary succession include fire, logging, or natural events like hurricanes or landslides. After the disturbance, the area is colonized by plant species that can readily grow in the existing soil, such as grasses, shrubs, or fast-growing pioneer tree species. These initial colonizers help stabilize the area and create conditions for other, more established plant species to return and eventually form a climax community.
In the given options, option B correctly states that primary succession begins with bare rock. This is a key characteristic of primary succession, as it differentiates it from secondary succession, which starts with existing soil. The other options mentioned in the question (options A, C, and D) are not accurate representations of the main difference between primary and secondary succession, making option B the correct answer.
It's correct by definition.

Succession. ... In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
