Explain why a significant spring death of adult shrews will lead to a sharp and prolonged decline in the population, while the complete destruction of all adult May beetles that emerged in spring will not lead to a similar result.
The population of shrews in spring is represented exclusively by adult animals of the last year of birth. May beetles, whose larvae develop in the soil for 3–4 years, have a complex age structure of the population. If adults die one spring the next year, they will be replaced by beetles that have developed from another generation of larvae.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
