To understand why hydras might avoid reproducing asexually when conditions are difficult, we need to consider the advantages and disadvantages of sexual and asexual reproduction.
Asexual reproduction is a form of reproduction that involves only one parent, and the offspring are genetically identical to the parent. This process is usually simpler and faster than sexual reproduction. However, it lacks genetic variation and does not provide an opportunity for adaptation to changing environments.
On the other hand, sexual reproduction involves the fusion of gametes (egg and sperm) from two parents, resulting in offspring with a combination of genetic traits from both parents. This genetic variation enhances the chances of survival, as it increases the potential for adaptation to changing conditions.
In difficult conditions, such as limited resources or increased competition, hydras would benefit from genetic variation that sexual reproduction provides. This allows for the potential production of offspring that may have advantageous traits, enhancing their survivability in challenging environments. Sexual reproduction also allows for the shuffling and rearrangement of genes, which can create new combinations of traits that may be beneficial for coping with difficult conditions.
In contrast, asexual reproduction in difficult conditions would lead to the production of genetically identical offspring, which lack the genetic diversity necessary for adaptation. This can be a disadvantage for hydras when faced with an unfavorable environment, as they would be limited to their existing genetic traits and have a reduced ability to respond and adapt.
Therefore, in order to increase their chances of survival and successful adaptation in challenging conditions, hydras would prefer to reproduce sexually, as it provides a broader range of genetic diversity and potential advantage over asexual reproduction.

Hydras may avoid reproducing asexually when conditions are difficult for several reasons:
1. Genetic Diversity: Sexual reproduction allows for genetic recombination, leading to offspring with different combinations of genes. This genetic diversity increases the chances of survival in changing and challenging environments.
2. Adaptation to New Environments: Sexual reproduction allows for the creation of new gene combinations, which may result in beneficial traits that can help individuals adapt and thrive in difficult conditions.
3. Resisting Diseases and Parasites: Sexual reproduction promotes genetic variability and helps prevent the accumulation of harmful mutations. This variability can enhance the Hydra's ability to combat diseases and parasites, which tend to become less effective when confronted with diverse genetic material.
4. Reproductive Flexibility: Sexual reproduction enables hydra to respond to changes in environmental conditions by producing offspring that are better suited to the current conditions. This flexibility can be crucial in challenging environments where asexually produced offspring may be less adaptive.
5. Long-term Survival: By avoiding asexual reproduction in difficult conditions, hydra can maintain a higher level of genetic diversity, improving their chances of long-term survival as compared to populations relying solely on asexual reproduction.
These are some possible reasons why hydra would avoid reproducing asexually when conditions are difficult.
