B They form a symbiotic association with plants, providing phosphorus and nitrogen water.
Correct Answer
C They are a significant food source for insects and other small animals.
D They produce potent mycotoxins that contaminate crops.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Mycorrhizae are symbiotic associations between fungi and plant roots. The fungi enhance the plant's uptake of water and nutrients (especially phosphorus and nitrogen), while the plant provides fixed carbon to the fungi. This is critical for forest ecosystems.

Hint

The name itself combines 'fungus' and 'root'.
