AP BIOLOGY

Detailed explanation-1: -Explanation: Biomes with higher temperatures and less precipitation tend to have shorter and less dense vegetation. Plants need water to growth by performing photosynthesis, therefore, less precipitation leads to short vegetation such as the one found in grasslands.

Detailed explanation-2: -The correct response is desert. The desert environment is characterized by low rainfalls (less than 25 cm per year). They are one of the most dry biomes on the planet. The desert biome also has highly variable temperature swings, with high temperatures during the day and low temperatures at night.

Detailed explanation-3: -Because climate determines plant growth, it also influences the number and variety of other organisms in a terrestrial biome. Biodiversity generally increases from the poles to the equator. It is also usually greater in more humid climates.

Detailed explanation-4: -The tropical rainforest biome has the most vegetation and biodiversity. It is the most species-rich biome, and contains the most amount of vegetation per unit area.

Detailed explanation-5: -That said, areas that have more precipitation tend to have more vegetation, and areas with less precipitation have less vegetation (refer again to the first image). On one extreme end of the spectrum, both the desert and tundra biomes receive very little rain, thus neither are very lush in terms of greenery.
