Question

Which of the following is an example of how soil invertebrates affect fungal competition?

		Selective feeding on some fungi can benefit the non-predated species.
		Invertebrates can transport fungal spores.
		Invertebrates that die provide resources/habitat that can become colonized by fungi.
		Invertebrates can disrupt the soil structure where fungi grow.

Which of the following statements is not supported in Crowther et al.(2011)? “Outcomes of fungal interactions are determined by invertebrate grazers”

		Fungi can not break down wood.
		Invertebrates can affect fungal community composition.
		Fungi contribute to carbon and nutrient cycling in soils.
		A fungal species can emit chemicals that harm or decrease growth in another species.

Answer 1

Question:

Answer:

(A): Selective feeding on some fungi can benefit the non-predated species.

Fungi communities and competition is not affected by predators very much but it effected by bottom parameters, i.e., available nutrients, competitive fungal species. Many invertebrate feed in some selective fungi which decrease the competition in that area by feeding whole fungi community.

(B): Fungi cannot break down wood.

Fungi release some chemicals which effect the growth of nearby species which is known as competitive inhibition. Invertebrate can affect the competition between fungal species by feeding on few of them. Fungi can grow on organic compound in recycle them. Fungi can grow on wood. Activity of invertebrates help them in providing nutrients easily.
