ECOSYSTEM TYPES

Which grassland has scattered trees?

A savanna is a tropical or subtropical grassland in which a continuous or nearly continuous herbaceous layer coexists with scattered trees and shrubs. Seasonal rainfall supplies enough water for some woody plants but not enough, or not consistently enough, to maintain a closed forest canopy. Fire and grazing are equally important: grasses can regrow from protected basal tissues, whereas frequent burning and herbivory limit many tree seedlings. Adult trees often have deep roots, thick bark, small leaves, or drought-deciduous foliage. The balance among rainfall, fire, soil, herbivores, and human

Which biome is most affected by seasonal fires?

“Savanna” for which biome is most affected by seasonal fires. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. A biome label describes a broad climatic and structural pattern rather than a single taxonomic assemblage. Similar climates can produce convergent vegetation on different continents even when the species themselves are unrelated. The remaining alternatives—“Tundra”, “Taiga”, “Temperate forest”—refer to different states, processes, or scales and therefore do not express the same causal rela

Which plant group dominates the savanna biome?

“Grasses” for which plant group dominates the savanna biome. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Terrestrial biomes are distinguished primarily by long-term temperature and precipitation regimes, their seasonality, and the vegetation physiognomy those conditions support. Latitude is informative only because it often covaries with climate. The remaining alternatives—“Trees”, “Shrubs”, “Epiphytes”—refer to different states, processes, or scales and therefore do not express the same causa
