Measure the amount of energy in the phytoplankton and the amount of light entering the aquarium. Then measure the amount of energy in the phytoplankton after exposure to the light and determine the difference.
Explanation:
Phytoplanktons like most of the plants use chlorophyll, sunlight and carbon di-oxide for photosynthesis but it depends on other organisms to consume extra energy as they are unable to gain enough energy from their consumption of light. This differs among the different species of planktons.
It can be observed in an aquarium that a phytoplankton is gaining less energy than the energy they have absorbed by the light and this can be done by measuring the energy before and after the photosynthesis.
Given what we know, we can confirm that among the options listed, the more appropriate example of positive phototropism is the <u><em>houseplant </em></u><u><em>growing towards the </em></u><u><em>window</em></u><u><em>. </em></u>
<h3>What is positive phototropism?</h3>
- This is a photosensitive reaction that occurs in plants.
- Positive phototropism is described as the growth of plants towards the source of light.
- While negative phototropism is when the plants lean away from the light.
- Sunflowers and bananas, which lean towards the sun as they grow, are prime examples of positive phototropism.
Therefore, given the definition of positive phototropism as the growth of an organism towards a source of light, we can confirm that the option stating that the <u><em>houseplant </em></u><u><em>grows towards the window</em></u> is the best example of this concept, given that the window is the source of light for the plant.

The primary function of the chloroplasts in a plant is to convert light
from the sun into glucose and energy in a process that is known as
photosynthesis. This energy is then used by the plant cells for
incredibly important functions such as growth and repair, so the chloroplasts are amongst the most necessary parts of any plant.
