The current increase of carbon dioxide in the atmosphere is as a result of human activities that began in the late 1700s. This period sparked the beginning of the Industrial Revolution and this is when we began to use fossil fuels. The burning of fossil fuels coupled with widespread global deforestation has led to a rise in CO2. Excess carbon dioxide in the oceans causes it to become more acidic. This acidity will affect marine species with shells like mussels and lobsters. <span />
Answer:
Soil
Explanation:
Ecological succession, which refers to the series of changes that occurs in an ecosystem over time, is of two types viz: primary succession and secondary succession. In primary succession, a new or barren area (usually a rocky surface) is colonized by organisms such as lichens called PIONEER SPECIES.
However, in secondary succession, an ecological disturbance such as natural disasters disrupt the ecosystem causing the area, which was made void, to be recolonized by organisms. Note that, despite the disturbances, a key factor which is SOIL is still present in the environment to sustain the growth of the recolonizing organisms in secondary succession
