7. (FGV) O estudo de uma cadeia alimentar em ambiente natural e equilibrado forneceu dados para a montagem da pirâmide ecológica 1. Tempo depois, uma das espécies dessa cadeia alimentar sofreu interferência antrópica direta, resultando em desequilibrio ecológico. Novos dados obtidos permitiram a construção da pirâmide ecológica 2. Essa dinâmica ecológica está representada nas imagens. A espécie que sofreu interferência antrópica direta nessa cadeia alimentar compõe o nível trófico correspondente aos a) produtores. b) consumidores primários.

## Step 1: Understanding the Pyramid Structure<br />### In ecological pyramids, the width of each layer typically represents the biomass or energy at each trophic level. The topmost layer usually represents the apex predators or tertiary consumers, while the bottom layer represents the producers.<br /><br />## Step 2: Analyzing "Pirâmide 1"<br />### "Pirâmide 1" shows a typical natural and balanced ecosystem where the producers (bottom layer) have the smallest biomass, followed by primary consumers, secondary consumers, and tertiary consumers (topmost layer) with the largest biomass.<br /><br />## Step 3: Analyzing "Pirâmide 2"<br />### "Pirâmide 2" indicates an imbalance caused by anthropic interference. Here, the second layer (primary consumers) has become the widest, suggesting an increase in their population or biomass. This implies that the primary consumers are thriving due to reduced predation or increased availability of resources.<br /><br />## Step 4: Identifying the Affected Trophic Level<br />### Given that the primary consumers' layer has expanded significantly in "Pirâmide 2," it suggests that the species which suffered direct anthropic interference were likely predators of these primary consumers. As a result, the primary consumers faced less predation pressure and their numbers increased.<br /><br />## Step 5: Conclusion<br />### The species that suffered direct anthropic interference are not the producers but rather those that interact directly with the primary consumers, leading to an increase in the latter's population.
