Ques: Q: What's the term for the gradual progression from simple plants to larger more complex ones in an area? Read this paragraph and choose the correct option from the provided answers: The pioneer species is soon replaced by other populations. Abiotic factors such as soil quality, water, and climate will determine the species that continue the process of succession. Mosses and grasses will be able to grow in the newly created soil. During early succession, plant species like grasses that grow and reproduce quickly will take over the landscape. Over time, these plants improve the soil and a few shrubs can begin to grow. Slowly, the shrubs are replaced by small trees. Small trees then are succeeded by larger trees. Since trees are more successful at competing for resources than shrubs and grasses, a forest may be the end result of primary succession. Choices: - complex progression - pattern progression - primary pattern - primary succession A:
Ans: primary succession
