The correct response is: No, because complex organisms like starfish and plants use asexual reproduction more often.
While it is common for multicellular, complex organisms to reproduce sexually, there are many exceptions where complex organisms can also reproduce asexually. For example, certain plants can reproduce through methods such as fragmentation or budding, and some animals, like starfish, can regenerate lost limbs and reproduce asexually. Additionally, some complex organisms, such as komodo dragons, can reproduce both sexually and asexually (parthenogenesis). Therefore, the statement is not always true.
