 rapidly, have no natural 
 in their new habitat, and can tolerate variation in their habitat condition.

The question describes traits that make invasive species successful: rapid spread, lack of natural enemies, and tolerance to environmental variation.

Option for 空白1: 'reproduce' 
- This fits logically: invasive species often proliferate quickly by reproducing at high rates, leading to rapid population growth and spread in a new environment. Other possibilities like 'disperse' or ' compete' would not directly capture the core biological mechanism of rapid expansion, whereas 'reproduce' specifically addresses the speed of population increase.

Option for 空白2: 'predators' 
- Placing 'predators' in the blank completes the idea that invasive species have 'no natural predators' in the new habitat, which reduces top-down control on their populations. While 'parasites' or 'competitors' could be relevant terms in broader discussions, the standard description of invasives emphasizes a lack of natural predators, making 'predators' the correct pairing here.

Why the other potential readings are less accurate:
- If 空白1 were something like 'disperse' or 'migrate', the sentence would not emphasize the intrinsic reproductive capacity that drives establishment and establishment speed, which is central to invasion biology.
- If 空白2 were 'competitors' or 'parasites', the sentence would shift focus to interactions other than the classic lack of natural enemies; though these factors matter, the conventional statement highlights 'no natural predators' as the key condition.

In summary, the intended fills are: 空白1 = reproduce and 空白2 = predators, aligning with the well-established idea that invasives often rapidly reproduce and experience reduced predation pressure in the new habitat, enabling tolerance of varied conditions and successful establishment.

Invasive species have various characteristics that promote their success. Specifically, they are likely to rapidly, have no natural in their new habitat, and can tolerate variation in their habitat condition.
