Question

large rocks at the back of a beach cause the wind speed to reduce. windblown sand begins to drop and build small sand piles, which create another windbreak and more sand is deposited. gradually, salt - tolerant grasses will begin to stabilize the sand dune with a vast network of root systems.
the process described is called __________.
○ primary succession
○ community ecology
○ secondary succession
○ ecosystems ecology

Explanation:

Primary succession occurs in an area where there was no previous community, starting from bare rock or sand. Here, the process starts with sand dunes forming due to wind - blown sand deposition and then plants colonizing the area, which is characteristic of primary succession. Community ecology focuses on interactions between species in a community. Secondary succession occurs in an area where a community previously existed but was disturbed. Ecosystems ecology looks at the flow of energy and matter in an ecosystem.

Answer:

primary succession
