Accepted Answer

The sentence refers to the effect of altered ocean currents on ecology. Since ocean currents are part of the marine environment, the correct word to describe the ecology affected by ocean currents is 'marine'. 'Grassland' and 'landscape' are terrestrial terms and do not relate to ocean currents. 'Biosphere' is a broader term encompassing all ecosystems but is less specific than 'marine' in this context. Therefore, 'marine' is the most appropriate choice.
