Why are ticks in nature?

Ticks, posing a threat to humans, also perform important functions in nature:
1. They are part of the food chain, being food, for example, for ants.
2. Ticks act as a regulator of natural selection. Some animals die after being bitten, while others survive. Thus, the number of individuals is regulated: the weak are eliminated, the strongest survive.
3. In addition to the above, ticks are also saprophages. Consuming and processing organic matter, they increase soil fertility.
