Tropical biomes are abundant in regions of hot and wet climate, while desert biomes are found in hot and dry climate.

Explanation:

Tropical Biomes:
Tropical biomes are characterized by their high temperatures and abundant rainfall throughout the year. These biomes are typically found near the equator and include rainforests, tropical seasonal forests, and tropical savannas. The combination of high temperatures and ample rainfall creates a lush and diverse ecosystem, with dense vegetation and a wide variety of plant and animal species. The high levels of rainfall support the growth of large trees, while the warm temperatures promote rapid decomposition of organic matter, leading to nutrient-rich soils.

Desert Biomes:
Desert biomes, on the other hand, are characterized by their extreme aridity and lack of precipitation. These biomes are typically found in regions with hot and dry climates, such as the Sahara Desert in Africa or the Mojave Desert in North America. Deserts receive very little rainfall, usually less than 250 millimeters per year, and experience high temperatures during the day and cooler temperatures at night. The lack of water limits plant growth, resulting in sparse vegetation, and the extreme temperatures and aridity make it difficult for many organisms to survive.

Contrasting Characteristics:
The key difference between tropical and desert biomes lies in their climatic conditions, particularly the amount and distribution of rainfall. While tropical biomes receive abundant rainfall throughout the year, desert biomes have very little precipitation. This difference in rainfall leads to distinct vegetation patterns and adaptations among the plant and animal species that inhabit these biomes.

Tropical biomes are characterized by their dense and diverse vegetation, with a wide variety of plant species, including tall trees, shrubs, and grasses. The high levels of rainfall support the growth of large trees, and the warm temperatures allow for year-round growth and high productivity.

In contrast, desert biomes have limited vegetation, with plants adapted to survive in arid conditions. These plants have developed various adaptations to conserve water, such as small leaves, thick waxy coatings, and deep root systems. Desert animals have also evolved to withstand extreme temperatures and limited water availability, with some species able to survive for long periods without drinking water.

In conclusion, tropical biomes are abundant in regions of hot and wet climate, while desert biomes are found in hot and dry climate. The key difference lies in the amount and distribution of rainfall, which leads to distinct vegetation patterns and adaptations among the plant and animal species that inhabit these biomes.
