Answer:
Step-by-step explanation:
A calcifuge is a plant that does not tolerate alkaline (basic) soil. The word is derived from the Latin 'to flee from chalk'. These plants are also described as ericaceous, as the prototypical calcifuge is the genus Erica (heaths).
What is the difference between calcicole and calcifuge?
Calcicole species (which grow on calcareous soil) exude much oxalic acid/oxalate, whereas calcifuges are much less able to do so, if exposed to calcareous soil or otherwise nutrient-poor conditions.
What is the habitat of a calcifuge?
Plants can be classified into two groups, calcifuges (e.g., rhododendrons, heaths, and azaleas), which grow in acid soils with low calcium, and calcicoles (e.g., the Brassicaceae family including cabbage, broccoli, and kale), which require calcium-rich soils.
