Question

Options

• time for the development of the soil horizons

• more time for the development of a seed bank

• colonization by organisms that are farther away

• redevelopment of the atmospheric gases

Answer 1

Primary succession takes much longer than secondary succession because it involves time for the development of the soil horizons.

Explanation:

It involves the gradual formation and development of soil horizons, as soil is essential for supporting plant life and the further development of the biological community. This process is slow, as it requires rock weathering and the accumulation of organic matter before other organisms can establish. In contrast, secondary succession begins where soil already exists, making it faster.
