Based on the abiotic factors described for the two biomes, the most reasonable statement about the biotic factors would be:
Animals in Biome A burrow into the loose sand to avoid the heat.
This statement is logical because Biome A is characterized by hot temperatures and loose, dry soil, which would likely lead animals to develop behaviors or adaptations to avoid heat, such as burrowing.
The other statements are less justifiable based on the abiotic conditions provided:
- Animals in Biome B having thick coats is less likely since it has moderate temperatures, which wouldn’t necessitate thick insulation.
- The assumption that conditions in Biome A are better suited for farming contradicts the limited rainfall characteristic of Biome A; it would not support farming as well as the moist, nutrient-rich soil of Biome B.
- There’s no supporting evidence that plants in Biome A would grow taller than those in Biome B given that Biome B has moist and nutrient-rich soil, which generally supports more substantial plant growth.
Thus, the first statement is the most reasonable choice.
