Answer :
In a wetland ecosystem experiencing a drought, the predator-prey relationship between a frog and a blue heron would likely be affected in the following ways:
1. **Decreased Prey Availability**: The drought can lead to a decrease in the water levels of the wetland, resulting in a reduction in the availability of aquatic prey for the blue heron, such as fish and frogs. This scarcity of prey can lead to increased competition between predators for limited food resources.
2. **Increased Predation Pressure**: With fewer places to hide due to lower water levels, frogs may become more exposed to predators like the blue heron. This heightened predation pressure can result in a decline in the frog population as they become more vulnerable to predation.
3. **Migration or Adaptation**: Some frogs may try to migrate to other wetland areas with more favorable conditions during the drought to escape predation by the blue heron. Alternatively, frogs may exhibit behavioral adaptations, such as changing their activity patterns or seeking refuge in remaining water bodies within the wetland.
4. **Impact on Food Chain**: The decrease in frog population due to predation by the blue heron can disrupt the food chain in the wetland ecosystem. This disruption can have cascading effects on other species that rely on frogs as a food source, potentially leading to imbalances in the ecosystem.
Overall, the effects of a drought on the predator-prey relationship between a frog and a blue heron in a wetland ecosystem highlight the interconnected nature of ecological systems and how environmental changes can influence species interactions and population dynamics.
