Chapter 35.3, Problem 1R
Summary Introduction
To review:
The changes that may occur if a land is suddenly irrigated heavily after being dry for many years and the result of cutting down a deciduous forest and replacing it with crops that have to be harvested every year.
Introduction:
Soil is a medium, in which plants grow and various living organisms thrive. The quality of the soil is dependent on environmental factors. Soil degradation has serious impacts on the ecosystem as plant growth depends on the soil quality. If the flora dies, the fauna in that area, in consequence, will die too.

Students have asked these similar questions
How can soil erosion lead to desertification?
It reduces the level of organic matter
It promotes flooding that destroys vegetation
It promotes salinization that destroys soil structure
Which of the following is not a factor that may lead to urban sprawl?
Pollution
Immigration
Overpopulation
Which statement is NOT true about soil salinization?
Soil dehydrates due to decrease in accumulation of water underground.
Starts by attempting to wash the salts out of the topsoil by pumping more water.
Results to the damage and killing of plants as saline water surrounds its deep roots.
Which would most likely happen if too much nutrient entered a freshwater ecosystem?
Algae will decrease, leaving few food resources, for fish.
Nutrients would sink to the bottom, increasing soil deposition.
Algae breakdown lowers dissolved oxygen, causing fish to suffocate.
Which of the following accurately describes life in soils?
A: Soil food webs lack complexity compared to above-ground ecosystems.
B: Soils contain both decomposers and predators that perform important functions.
C: We would need to collect a large soil sample size to find many species.
D: Soil biota sometimes support plants in taking up nutrients.
E: B and D.
F: B, C, and D.
Think about how humans rely on soil. From a human point of view, how has glaciation had a good and bad effect on Canada’s soils? A soil can include particles ranging in size from very fine clay to coarse sand. Why is neither of these soils ideal for plant growth, including agriculture?
