What is one difference between primary and secondary succession?

a. primary succession is rapid and secondary succession is slow.
b. secondary succession begins on soil and primary succession begins on newly exposed surfaces.
c. primary succession modifies the environment and secondary succession does not.
d. secondary succession begins with lichens and primary succession begins with trees.

One difference between primary and secondary succession is that; the secondary succession begins on soil while primary succession begins on newly exposed surfaces.

The difference between the primary and secondary succession is that the primary succession initiates in the newly exposed surface and the secondary succession begins on the soil.

Further Explanation:

Succession is the continuous process by which a biological community evolves with the time.

There are two kinds of succession. They are:

1. Primary succession: Generally occurs in the area where there was no life earlier or it is the newly exposed surface formed due to flow of lava, newly formed rocks or a sand dunes.

2. Secondary succession: Generally occurs in the region where community already existed and later it was removed due to some disturbances. This leads to retention of nutrient in that environment.

Both the succession leads to development of the continuous changing diversity of species within a community as disturbances of different intensities, frequency and sizes changes the landscape.

The preceding habitants modifies the environment for the growth of later species.

The succession at some areas reaches the climax stage that develops a stable community or an equilibrium stage in which there develops a strong web of biotic interaction.

i don't think that you should. it looks amazing to me! it is definitely a lot better than the things that i can draw ; ~ ;

either online or traditional classroom can work for students. which is better will depend on students and teacher. students may have trouble following a lesson in classroom while they can study at their own pace online. other students may have trouble staying focus on their own in online classes. teachers are more used to classroom teaching but they may also be more worry about their jobs teaching online classes and work harder.
