Question

The dominance of therophytes in a particular area would indicate that climate is (i) warm and dry (ii) warm and moist (iii) extremely cold (iv) cold and dry​

Answer 1

Answer:

the dominance of the therophytes in a particular area would indicate extremely cold climate

Answer 2

Temperature control in a particular area may indicate that the climate (iv) is cold and dry:

• Hemicryptophyte and chamaephyte dominance is common in cooler climates and has a number of features that apply to large, mesh, and small climates.
• Therophyte dominance is often associated with adverse dry conditions.
• A high percentage of therophytes in any region indicated that the region had a dry climate and disturbed habitats.
• On the other hand, the chamaephyte exhibits a cool phytoclimate.
• Thus, the apparent dominance of therophytes followed by chamaephytes over other species in the Riyadh region is evident.
• On the basis of hemicryptophyte and therophyte dominance, local phytoclimate as the term Raunkiaer means can be described as a Hemicrypto-Therophytic type.
• The high percentage of hemicryptophyte and therophyte is a feature of the dry climate and the Ladakh region reflects this type of climate.
