Final answer:
Lee chose to study tiny microorganisms, including algae, in a tidal pool for his science project, recognizing their importance in the aquatic ecosystem and potential uses like biodiesel production.
Step-by-step explanation:
For his science project, Lee chose to study the tiny microorganisms of a tidal pool. The unique characteristics of algae, which are often considered simple plants, make them an interesting subject within the discipline of microbiology. Algae play a crucial role in the food web by providing a food source for different species and by contributing to natural processes such as the production of oxygen through photosynthesis.
They can be grown in large quantities and have potential applications, like being turned into biodiesel. Leeuwenhoek, using his microscope, discovered various forms of microorganisms, including what he called 'animalcules', which are today known as bacteria. These microscopic organisms, like algae, form part of the vast diversity of life in aquatic ecosystems.
