Answer is: active transport.
In active transport<span> because energy is required to move the sodium and potassium ions against the concentration gradient. There is two type of active transport:
1) </span>Primary active transport directly
uses metabolic energy (adenosine triphosphate- ATP) to transport molecules
across a membrane.
2) In secondary active transport (coupled
transport) there is no direct coupling of ATP, energy derived from
the pumping of protons across a cell membrane.

Explanation:
Precipitation is basically the weather, the people that come to the park would want a clean park which means that that would increase, and temperature is based on weather.
1. Living and non living things in an ecosystem are called biotic and abiotic factors respectively.
Living things include: plants, animals, microorganisms and non-living things include: sunlight, temperature, gases, water etc.
2. Ecosystem, population, biosphere, community.
The question above is about an experiment that was performed on eyes.
The experiment involves covering the left eyes of the experimental subject while the right eye is exposed to light at different distances and the correspondent size of the pupil measured.
In the graph given for the experiment, the largest decrease in the size of the pupil take place between 7 and 8 distances. At distance 7, the size of the pupil is 4mm while at distance 8, the size is 1mm, which means that, there is a decrease of 3mm in pupil size. This is the largest decrease on the graph.
