Question

categorize each description as an example of primary or secondary succession. primary succession secondary succession a volcano erupts, converting a field of grass to bare rock. a lichen and moss community colonizes the rock. a volcano erupts, converting a field of grass to bare rock. a forest community colonizes the rock. a glacier melts creating a lake from a valley. an aquatic community colonizes the lake. loggers remove an acre of trees from the middle of a jungle. other species of trees fill in the vacant space.

Explanation:

Primary succession occurs in lifeless areas where soil has not yet formed (e.g., bare rock from volcanic eruption, new lake from glacier melt). Secondary succession happens in areas where a disturbance (like logging) removes vegetation but soil and some organisms remain.

Answer:

• "A volcano erupts, converting a field of grass to bare rock. A lichen and moss community colonizes the rock." - primary succession
• "A volcano erupts, converting a field of grass to bare rock. A forest community colonizes the rock." - primary succession
• "A glacier melts creating a lake from a valley. An aquatic community colonizes the lake." - primary succession
• "Loggers remove an acre of trees from the middle of a jungle. Other species of trees fill in the vacant space." - secondary succession
