As you are walking through a forest in Ohio, you notice that there are many large, mature trees. But you also notice patches of
young seedlings where storm damage has cleared some openings. From a distance, the forest looks like it is made of all large and mature trees. But now, it is clear that the forest consists of young and old trees in a sort of mosaic of different ages and species. As you walk along, you notice that the understory is largely free of woody debris. This particular forest represents the __________ stage of forest succession.
Secondary succession occurs when the existing vegetation is removed by some disturbances and soil is already present in the region to support the growth of new species. During succession, the early species are being replaced by later successional species.
In the given example, the forest has patches of early species and later species. This means that the forest is in the transition period of succession where early species were not completely replaced by the new species. Once the early species will be removed and the climax community develops, the forest has reached the final stage of succession.
Yes, it does, but not the way people think. it doesn't gain it from the weight of all the people. the earth takes mass from elsewhere, as our population continues to grow.
