Question
The food web below shows the feeding relationships of six different populations in an ecosystem.
The energy pyramid diagram below is separated into three sections. The lowest section represents producers, which have the largest populations in stable ecosystems. The middle section represents primary consumers. The top section represents secondary consumers. In ecosystems where secondary consumers are the top trophic level, these populations are the smallest in the ecosystem.
Based on the food web, place the name of each population in the correct box on the energy pyramid diagram.
ladybug
aphid
grass
owl
mouse
snake

To place the populations in the correct sections of the energy pyramid based on the given information:
1. **Producers (Lowest Section)**: This is where the organisms that produce their own energy (photosynthetic organisms) will be placed. In this case, the **grass** should go here.
2. **Primary Consumers (Middle Section)**: This section includes herbivores or organisms that eat producers. In this food web, the **aphid** (which eats grass) and the **mouse** (which may also eat plants or herbivores) would be considered primary consumers. Therefore, both **aphid** and **mouse** should be placed in this section.
3. **Secondary Consumers (Top Section)**: This section includes organisms that are carnivores that eat primary consumers. In this case, the **ladybug** (which eats aphids), the **snake** (which may eat mice), and the **owl** (which could eat both mice and snakes) would be classified as secondary consumers. Therefore, **ladybug**, **snake**, and **owl** should be placed in this section.
Here's how the energy pyramid will look:
- **Producers**: Grass
- **Primary Consumers**: Aphid, Mouse
- **Secondary Consumers**: Ladybug, Snake, Owl
