Verified step by step guidance1
Begin by understanding what a biome is: a biome is a large ecological area on the Earth's surface, with fauna and flora adapting to their environment. Biomes are defined by factors such as climate, soil, and vegetation.
Consider the statement about biomes occurring on every continent. While some biomes, like deserts or forests, can be found on multiple continents, not every biome type is present on every continent due to varying climatic conditions.
Evaluate the statement regarding unique groups of species. Biomes are indeed characterized by specific groups of plants and animals that have adapted to the particular conditions of that biome, making this statement generally correct.
Analyze the statement about human activity. Human activity, such as deforestation, urbanization, and pollution, significantly impacts most biomes, altering their natural state and sometimes leading to degradation.
Reflect on the statement about temperature and precipitation. These are indeed the major factors affecting the distribution of biomes, as they determine the climate conditions that define each biome's characteristics.
