Answer to Question #127699 in Ecology for Kylie

Question

. All of the following are associated with microbial soil ecology except ____.
1. organic matter.
2. carbon to nitrogen ratio.
3. humus.
4. marine snow.

Answer 1

Answer:- option 4.marine snow.

Explanation:- organic matter, C to N ratio and humus is part of microbial soil ecology, except Marine Snow.

Microbial soil environment which includes bacteria, fungi and other microbes is comprised of mainly plant roots, microbial and animal biomass, organic matter, and mineral materials etc.

In which soil organic matter is organic matter components of soil environment.and this organic matter form detritus at various stages of decomposition of cells and tissues of plant and animal by soil microbes and substance that synthesis by soil microbes.

Carbon to Nitrogen ratio is also a part of microbial soil ecology as C/N ratio is a ratio of mass of C to the mass of N in a substance.

C to N ratio is useful for understanding sedimentary organic matter , which can lead to easy study of soil ecology, and climate.

Humus is component of microbial soil ecology no dought, as humus is cellular cake structure characteristics of plant and animal including soil microrganism.

It's a dark organic matter formed in soil environment, by death of plant and animal , which breakdown further through anaerobic organism.

Marine Snow last option is not a part of microbial soil ecology, because it's made up of mostly of organic matter, fecal matter of various marine organisms and small animal included dead animal and phytoplanktons , protista etc. In Marine or Ocean ecology.

Thank you.
