Verified step by step guidance

Understand the concept of a biome: A biome is a large ecological area characterized by specific types of plants, animals, and climate conditions. It is influenced by abiotic factors such as temperature, precipitation, and soil type.

Recognize the role of climate: Climate, which includes temperature and precipitation, is the primary factor that determines the types of plants and animals that can thrive in a biome. For example, deserts have low precipitation and high temperatures, supporting drought-resistant plants and animals, while rainforests have high precipitation and warm temperatures, supporting diverse species.

Eliminate irrelevant factors: The altitude of the nearest mountain, the number of rivers present, and the age of the biome are not primary determinants of the types of plants and animals in a biome. These factors may influence local ecosystems but are secondary to climate.

Connect temperature and precipitation to adaptations: Plants and animals in a biome have adaptations that allow them to survive in the specific climate conditions. For instance, cacti in deserts store water to survive low precipitation, while animals in tundras have thick fur to endure cold temperatures.

Summarize the importance of climate: Climate sets the foundation for the biome's ecosystem by shaping the environment and determining which organisms can survive and reproduce. Temperature and precipitation are the key components of climate that directly influence biodiversity in a biome.
