A popular species of fish were split by the formation of the isthmus of panama a long time ago. The fish developed changes in their genes to adapt to the new environment and become two different species. This is not because of fish trying to adapt to the new environment but due to the restriction of the gene flow in the fish population. The gene flow maintains the diversity of the different forms of the genes in a population. When it gets restricted the two split populations gradually start to differentiate in terms of the traits they exhibit. At times it can lead to the extinction of one set of population.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
