2. In 2012 some Harvard graduates were asked a simple question: Where does a plant get
its mass? Many of the students answered incorrectly that plants gained mass from
"eating" the soil.
a. Using specific information from your equational model, explain where plants
actually get their mass.
b. Propose a simple experiment that could support your explanation.

The mass of a tree is primarily carbon.

Explanation:

The carbon comes from carbon dioxide used during photosynthesis.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
