Question

A fungus increases the ability of a plant to grow under high-salt conditions. For the plant, this association is a _______ mutualism?

1) trophic
2) formic
3) chemical
4) habitat

Answer 1

The association between a fungus and a plant that increases the plant's ability to grow under high-salt conditions is an example of chemical mutualism. (option 3)

Step-by-step explanation:

The association between the fungus and the plant, where the fungus enhances the plant's growth under high-salt conditions, is an example of chemical mutualism. In this mutualistic relationship, the fungus likely contributes by aiding the plant in nutrient absorption, particularly under challenging conditions like high salinity. The fungus may assist in nutrient mobilization or provide the plant with protective mechanisms against salt stress, leading to improved growth and survival.

Chemical mutualisms involve the exchange of biochemical signals or substances that benefit both organisms involved. In this case, the plant and fungus collaborate chemically to enhance the plant's ability to thrive in high-salt environments. Such mutualistic interactions are essential for the adaptation and resilience of plants in diverse ecological conditions.

The chemical mutualism between the fungus and the plant exemplifies the collaborative exchange of substances, demonstrating the adaptability of organisms to challenging environmental conditions and highlighting the intricate relationships in ecosystems.
