How is soil a complex ecosystem?
Expert Solution & Answer
Summary Introduction
To determine: What makes soil a complex ecosystem.
Introduction: The interactions among the organisms that live together in a particular place and interaction among these organisms with their abiotic environment are referred to as ecosystem. Soils are rich ecosystems that consist of both living and non-living matter with a number of interactions between them.
Explanation of Solution
Soil consists of small particles that vary in size. They are formed by weathering of rocks. They are composed of various organic and inorganic components which are responsible for nutrient cycling, greenhouse emissions, modifying soil structure, and for enhancing plant health. Some farming practices can reduce the mineral content of the soil; the aim of soil conservation is to reduce the risk of soil damage. The number and type of species of microorganisms present in the soil depend upon the environmental conditions, aeration, temperature, pH, and variable food resources. Therefore, the soil may look static, but it is a rich and complex ecosystem.

The Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows:
aabb: yellow
AABB, AABb, AaBb, and AaBB: red
AAbb and Aabb: orange
aaBB: yellow
aaBb: ?
Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why?
Question 21 options:
orange because A is epistatic to B
yellow because A is epistatic to B
red because B is epistatic to A
orange because B is epistatic to A
red because A is epistatic to B

So you make the same cross again (between a homozygous black seeded, mold susceptible parent and a homozygous white seeded and mold resistant parent), and, again, advance progeny by SSD to create 100 F10 generation plants. Based on the information you obtained from your first crossing experiment (Question #4), how many F10 plants would you expect to have black seeds and be resistant to mold? Assume that a toxin produced by the mold fungus has been isolated. Only mold resistant seeds will germinate in the presence of the toxin. Could you use this toxin screening procedure to have segregation distortion work in your favor in the F2 generation? Explain your answer. Info from Question 4 a. P Locus (Seed Color): Hypothesis: The null hypothesis (H₀) is that seed color is controlled by alleles at a single locus.
