No, this statement is not always true. While it is generally true that complex organisms tend to reproduce sexually and simple organisms tend to reproduce asexually, there are exceptions to this rule. There are some complex organisms that reproduce asexually, such as certain species of plants and fungi, while some simple organisms, such as some bacteria and protists, can reproduce sexually. Additionally, there are some complex organisms that have the ability to reproduce through both sexual and asexual means. Therefore, while the statement may hold true in many cases, it is not always the case and there are exceptions.
