Ecological importance of frog is 

Options

A. reduce insects and forms important link of food chain
B. increases insects and forms important link of food chain
C. maintains prey numbers
D. amphibian animal to maintain temperature

Answer

### Step-by-Step Solution

1. **Understanding the Role of Frogs in the Ecosystem**: Frogs are amphibians that play a crucial role in their ecosystems. They are primarily insectivorous, meaning they feed on insects.

2. **Reduction of Insect Population**: By preying on insects, frogs help to control and reduce the population of these insects in their environment. This is important because an overpopulation of insects can lead to various ecological imbalances.

3. **Link in the Food Chain**: Frogs serve as an important link in the food chain. They are both predators and prey. As they consume insects, they help maintain the balance of the ecosystem. Additionally, frogs themselves are a food source for larger predators, such as birds and snakes.

4. **Maintaining Ecological Balance**: By controlling insect populations, frogs help maintain the overall ecological balance. This balance is crucial for the health of their habitats, as it ensures that no single species dominates the ecosystem.

5. **Conclusion**: The ecological importance of frogs can be summarized as follows: they reduce insect populations, serve as a vital link in the food chain, and contribute to the maintenance of ecological balance.

### Final Answer
The ecological importance of frogs includes reducing insect populations and forming an important link in the food chain.
