Answer:

The first organisms present during primary succession are typically organisms such as lichens, algae, and other pioneer species that are very hardy and do not require soil.

Explanation:

While this will depend somewhat on the exact environment, the first organisms present during primary succession are typically organisms such as lichens, algae, mosses, fungi, and other pioneer species that are very hardy. These pioneer species or colonizers are able to survive and thrive in environments (bare rock, sand, etc.) that other organisms would not.

When they die, they decompose and their remains enrich the environment and make it easier for other species to grow. Pioneer species are a crucial part of any newly forming soil, providing nutrients and adding organic material.
