What is the difference between primary and secondary succession?

• Primary succession already has soil.

• Primary succession has soil and secondary succession does not.

• Soil is present in both primary and secondary succession.

• Primary succession has no soil and secondary succession has soil.

Why does primary succession take longer to reach climax community?

• Because trees do not perform photosyntheses.

• Because climax community is in a forrest.

• Because primary succession already has soil

• Because primary succession does not have soil
