B. frog
C. snake
D. grass

Answer

To determine the secondary consumers in the given food chain (grass-insect-frog-snake-hawk), follow these steps:

### Step 1: Identify the Producers
- In a food chain, the first level consists of producers, which are organisms that can produce their own food through photosynthesis. In this case, **grass** is the producer.

### Step 2: Identify the Primary Consumers
- The next level consists of primary consumers, which are organisms that eat producers. Here, the **insect** consumes the grass, making it the primary consumer.

### Step 3: Identify the Secondary Consumers
- The next level in the food chain consists of secondary consumers, which are organisms that eat primary consumers. In this case, the **frog** eats the insect, making it the secondary consumer.

### Step 4: Identify the Tertiary Consumers
- The level above the secondary consumers consists of tertiary consumers, which eat secondary consumers. In this food chain, the **snake** consumes the frog, making it a tertiary consumer.

### Step 5: Identify the Quaternary Consumers
- Finally, the top level consists of quaternary consumers, which are the top predators in the food chain. Here, the **hawk** consumes the snake.

### Conclusion
- Therefore, in the food chain grass-insect-frog-snake-hawk, the secondary consumers are **frogs**.
