Answer:
The correct answer is "plants"
Step-by-step explanation:
Biomes are defined as large communities found in nature at which species of animals and plants coexist and interact. An ecologist could guess what type of biome is studying if she or he knows what type of plants are in the area. Plants function as the producers in the biome, and since they are the higher thropic level in the food chain, it is possible to predict which type of herbivores and carnivores would live in the same area.
