Question
Chapter 35, Problem 2ITD
Summary Introduction
To review:
The ratio of lignin to nitrogen in leaf litter seems to correlate with total litter nitrogen content.
Introduction:
Plants require essential nutrients in the form of macronutrients (carbon, hydrogen, oxygen, and nitrogen) and macronutrients (zinc, chlorine, copper, iron, and manganese). They are required for the formation of some of the key structural components of plants.

Students have asked these similar questions
We have 2 types of soils. One soil has bulk density of 2.75g/cm^3; second has bulk density of 1.5g/cm^3. What guess will we get from this information about the following soil properties for both soils?
a. Soil structure
b. Porosity
c. Root penetration
d. Presence of organic matter
Which of the following is not a soil structure types?
Group of answer choices
True
False
a) Granular,
b) Crystalline
c) Angular blocky
d) Columnar/prismatic
e) Platy
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.
