Choose the word for each blank.
In a new study 1 in the journal Nature Communications, scientists from the universities of Nottingham and Durham and the British Geological Survey (BGS), have discovered the cause of a mass extinction within marine organisms called foraminifera. Foraminifera are an important group in relation to biomass in the deep ocean and the cause of their extinction was 2 unknown. Scientists tested various possible 3 for the mass extinction and were able to discount others such as ocean cooling. 4 they discovered that the extinction was caused by a global change in plankton at the surface of the ocean.
