During interphase, the cell copies its DNA in preparation for the second stage of meiosis.
Prophase is the first stage of cell division, in which the chromosomes become visible as paired chromatids and the nuclear envelope disappears.
Metaphase is the second stage of cell division in which the chromosomes become attached to the spindle fibers.
Anaphase is the third stage of cell division, in which the chromosomes move away from one another to opposite poles of the spindle.
Telophase is the fourth stage of cell division, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
Cytokinesis is the division of a cell at the end of mitosis or meiosis that separates the cells into two individual daughter cells.
Answer:
Transition
Explanation:
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.
