IB Biology SL 3.4.7 Biomes and Biosphere Question Bank

G3. (a) correctly named biome; temperature range;
dominant plant/ecosystem characteristics;

Marking guidance:

Allow any other appropriate characteristic. e.g.: temperate deciduous forest;
warm $/ 15-18^{\circ} \mathrm{C}$ summers and cold $/ 3-7^{\circ} \mathrm{C}$ winters / significant annual temperature variation;
broad leaf trees (that lose leaves annually) / significant diversity of understory plants;

The following provides further examples of biomes that may be addressed. Answers do not need to be shown in a table format.

named biome

temperature range

dominant plant / ecosystem characteristics

desert;

hot ( $30^{\circ} \mathrm{C}+$ ) in day and cold (below zero) at night ;

xerophytes / succulent / sparse lowlying bushes adapted to water conservation;

savannah;

hot ( $20-30^{\circ} \mathrm{C}$ );

grasslands with widely spaced trees;

tropical rainforest;

very hot $\left(25-30^{\circ} \mathrm{C}\right)$;

epiphytes / trees and wide leaf plants in undergrowth / huge diversity / tall mature trees of many species;

taiga;

cold (below $0-15^{\circ} \mathrm{C}$ );

coniferous/evergreen trees densely packed (few species);

tundra;

minus temperatures for most of the year;

small and close to ground / grasses and mosses with a few small trees (perennial herbs grow in summer);
