Question

56 A. A single litterbag with poplar leaf litter has been placed on the forest floor at Coweeta. This bag was harvested and arthropods extracted from it.

At which stage of decomposition is the leaf litter in this litterbag when it was harvested?

A) Fresh

B) Early

C) Mid

D) Late

56 B. How do microarthropods interact with soil fungi?

Check all that apply:

A) Microarthropods distribute fungal spores to new substrates.

B) Microarthropods provide new substrates for fungi by producing nutrient-rich fecal matter.

C) Microarthropods increase utilization of litter for fungi by fragmenting coarse litter.

Explanation / Answer

(A) The poplar plant is at Late stage. When we say litter we say it a waste, then when we say mites, they accumulate over late leafs, (B) microarthropods carry fungal spores stuck on their legs so that they get new substrate. Fungus grow over decaying organic matter indicating that the leafs are in late satge.
