Select a food chain from the food wob and use it to drow a fully tabellod food pyramid of energy 4 trophic levels.

To create a food pyramid of energy with four trophic levels, we can use the following food chain as an example: 1. **Producers**: Grass (plants) 2. **Primary Consumers**: Grasshoppers (herbivores) 3. **Secondary Consumers**: Frogs (carnivores) 4. **Tertiary Consumers**: Snakes (top predators) ### Energy Pyramid Structure 1. **Producers (Grass)** - Energy Source: Sunlight - Energy Level: Highest (100% of energy) 2. **Primary Consumers (Grasshoppers)** - Energy Level: Approximately 10% of the energy from producers (10% of 100% = 10%) 3. **Secondary Consumers (Frogs)** - Energy Level: Approximately 10% of the energy from primary consumers (10% of 10% = 1%) 4. **Tertiary Consumers (Snakes)** - Energy Level: Approximately 10% of the energy from secondary consumers (10% of 1% = 0.1%) ### Energy Pyramid Table | Trophic Level | Organisms | Energy Level (%) | |-----------------------|------------------|------------------| | Producers | Grass | 100 | | Primary Consumers | Grasshoppers | 10 | | Secondary Consumers | Frogs | 1 | | Tertiary Consumers | Snakes | 0.1 | ### Explanation - **Producers** are at the base of the pyramid and have the highest energy level because they convert sunlight into energy through photosynthesis. - **Primary consumers** (herbivores) obtain energy by eating producers, but they only receive about 10% of the energy from the plants they consume. - **Secondary consumers** (carnivores) eat primary consumers and receive about 10% of the energy from them. - **Tertiary consumers** (top predators) receive only about 10% of the energy from the secondary consumers. This structure illustrates the energy loss at each trophic level, which is a fundamental concept in ecology.
