Sedaia [141]

Answer

Ocean acidification results from the solubility of CO2 in oceans increasing the H+ concentrations, and depletion of bicarbonates concentrations.

Therefore, human activities which increases the concentration of CO2 in the atmosphere, will raise the atmospheric  CO2 concentration. CO2 is constantly being absorbed by green plants maintaining   its concentration through carbon cycle,Therefore massive deforestation  which removes green plants, cutting  down photosynthesis is one of human activities which  raises CO2 levels of the atmosphere.The CO2 dissolves in  the oceans to raise its acidic levels.Lower pH.

Another source is fossil fuels emissions which add more CO2 to the atmosphere.

What is the likely effect of removing the wildcat on the population of ows and rabbits.
emmasim [6.3K]

Answer:

Rabbits would survive because there's 1 less predator preying on them, therefore they will reproduce more rabbits and rabbits will overpopulate. And the same thing will happen with the mice, therefore the owls will have less competition over food and their population will grow.
