What are the key characteristics of tropical rainforests located near the equator, and why do they support such high biodiversity?
Tropical rainforests near the equator have consistently high temperatures and significant rainfall year-round, leading to dense vegetation with vertical layering. This creates diverse habitats, supporting over 50% of the world's species and resulting in extremely high biodiversity. How do savannahs differ from tropical rainforests in terms of climate and vegetation, and what ecological processes are important in savannahs?
Savannahs, or tropical grasslands, have a warm climate with a long dry season and scattered trees among grasslands. Frequent wildfires, driven by the dry season, are important ecological disturbances, and many species are adapted to survive drought and fire. What adaptations do plants and animals in deserts near the equator have to survive their environment?
Plants and animals in deserts have evolved adaptations to conserve water and tolerate extremely dry conditions, as deserts are characterized by low precipitation, low biomass, and highly variable temperatures. What climatic conditions are typical of tropical rainforests near the equator?
Tropical rainforests have consistently high temperatures and significant rainfall year-round. These conditions support dense vegetation and high biodiversity. How does vertical layering in tropical rainforests contribute to biodiversity?
Vertical layering creates multiple habitats at different heights, allowing many species to coexist. This structural complexity supports over 50% of the world's plant and animal species. What distinguishes savannahs from regular grasslands in terms of vegetation?
Savannahs have expansive grasslands with scattered trees, unlike regular grasslands which lack significant tree cover. The presence of scattered trees is a key distinguishing feature. How does the climate of savannahs differ from that of tropical rainforests?
Savannahs have a warm climate with a long dry season and a distinct wet season, while tropical rainforests have high rainfall throughout the year. The dry season in savannahs leads to frequent wildfires. Why are wildfires important in savannah ecosystems?
Wildfires are an important ecological disturbance in savannahs, shaping the ecosystem by clearing old vegetation and promoting new growth. Many species in savannahs are adapted to survive these fires. What are the main environmental challenges faced by plants and animals in deserts near the equator?
Deserts have extremely low annual precipitation, low biomass, and highly variable temperatures. Plants and animals must conserve water and tolerate dry conditions to survive. How have desert organisms adapted to survive in their harsh environment?
Desert plants and animals have evolved adaptations to conserve water and withstand extreme dryness. These adaptations are crucial due to the scarcity of liquid water in deserts.
