Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations in check. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. For their part, protozoa are important food sources for many larger organisms, including insects and worms.

In general, the trend from the nineteenth century to now when it comes to masturbation and sexual intercourse is one of increasing acceptance. However, this is not true in all communities. During the nineteenth century, people considered masturbation to be wrong in all situations, while sexual intercourse was only proper between married couples for the purpose of procreation. While some people disagreed with these views, those who disagreed generally kept quiet as this was a social taboo. Nowadays, many people still have these views and still consider the subjects taboo, but the situation is a lot less universal.
If I had lived in the nineteenth century, it is very unlikely that I would have been able to discern the cultural values and taboos surrounding these practices. This is because people are generally not very good at examining the contingency of the values of their own time period. In the same way, I generally agree with the values that are promoted nowadays regarding these topics.
