We would expect the greatest difference in plant health between two groups of plants of the same species one group with mycorrhizae and one group without mycorrhizae in an environment?

Answer 1

Possible answers:

A) where nitrogen-fixing bacteria are abundant.

B) that has soil with poor drainage.

C) that has hot summers and cold winters.

D) in which the soil is relatively deficient in phosphorus.

E) in which the soil is relatively deficient in nitrogen.

Answer 2

A mycorrhizal association can enhance plant health by improving nutrient uptake, especially phosphorus. Therefore, in environments deficient in phosphorus, plants with mycorrhizae are likely to exhibit significantly better growth and health compared to plants without mycorrhizae. This difference may be less pronounced in environments where phosphorus is readily available to plants.
