Question

number correct 14 number incorrect 3 a volcanic island forms as lava from the earth builds up and cools to form rock in the ocean. lichens start to grow, followed by small plants, then larger plants, and eventually trees. animals also start to colonize the island as the plant communities change. ultimately a rainforest ecosystem thrives on the island and remains for a long period of time. this process is called... a. secondary succession b. primary succession c. a climax community d. pioneer species

Explanation:

Primary succession occurs in an area where there was no previous soil or life, like on a new volcanic island. Lichens are pioneer species that start the process, followed by other plants and animals until a climax community (like the rainforest ecosystem here) is reached. Secondary succession occurs in an area that had previous life and soil. Pioneer species are the first - colonizing organisms, and a climax community is the stable, final stage of succession. Since this is the start of life on a new, barren island, it's primary succession.

Answer:

B. primary succession
