Relate this in terms of time, nutrients, and topsoil. Secondary succession is gradual, always moving toward the climax community.

Primary succession refers to the colonization of barren areas where no life previously occurred.Secondary succession refers to the colonization of areas where a previous ecological community existed and was either partially or completely removed by a disturbance.
