For Achieved, the student needs to describe a life process of a microorganism and describe an abiotic or biotic factor within an interconnected environment that affects the life process of the microorganism, using observations. 

The student has described reproduction and nutrition in Escherichia coli (only one life process needs to be described).

They have described a range of temperatures within the human host that affects the life process, using observations. This includes stating that there was slow growth at fridge and freezer temperatures, growth at 26 degrees Celsius, and restricted growth at 40 degrees Celsius. 

For Merit, the student could link a change to an abiotic or biotic factor of the interconnected environment to the effect on the life process of the microorganism, using observations.

For Merit, the student needs to link a change to an abiotic or biotic factor of the interconnected environment to the effect on the life process of the microorganism, using observations. 

The student has described movement in Phytophthora agathidicida and has described a range of soil moisture levels that affects the life process, using observations.  

They have linked a change in water availability in the ngahere to the effect on the movement of P.agathidicida, using secondary data. This includes linking the relative moisture levels of the soil to the ability of the zoospores to move towards the kauri roots.

For Excellence, the student could examine how the life process of the microorganism affects an abiotic or biotic factor of the interconnected environment, using observations. 

For Excellence, the student needs to examine how the life process of the microorganism affects an abiotic or biotic factor of the interconnected environment, using observations. 

The student has described respiration in yeast and has described a range of temperatures that affects the life process, using observations.  

They have linked a change in temperature to the effect on respiration in yeast, using observations.

The student has examined how respiration affects oxygen levels in the interconnected environment, using observations. This includes examining how using oxygen during respiration reduced oxygen levels in the interconnected environment.
