Answer

  1. Slowly increasing

Explanation:

Ecological succession is the gradual process by which ecosystems change and develop over time.

With the habitats, constantly changing, succession is of two types- primary and secondary.

Succession develops through increasing complexity until it becomes stable or self-perpetuating as a climax community where the ecosystem is balanced and there is less risk of any interfering event or change to the environment.
