What could be added to the diagram to show the tree’s contribution to the carbon cycle?

• arrows to show carbon dioxide entering the tree during photosynthesis

• arrows to show carbon dioxide leaving the tree during sedimentation

• decomposers breaking down the dead matter to release carbon

• an arrow from the chipmunk to the acorn to show the sharing of carbon

Biogeochemical cycles are evidence that the biosphere follows the law of conservation of mass. Based on the diagram, what happened to the matter that made up the needles of the trees that are burning?

• It was destroyed by the fire

• It became smoke, ash, and gases

• It fell to the ground unchanged

• It was converted to energy by the flames

During the forest fire, chemical potential energy is converted to thermal energy when trees and plants burn. How does this demonstrate the law of conservation of energy?

• Heat is transferring to the forest’s surroundings

• Energy is changing form

• Some plants and animals survive

• Energy continues to enter the ecosystem

During the forest fire, smoke from the fire moves into the surrounding ecosystem, blocking some sunlight. What effect might this have on the plants in those nearby ecosystems?

• They produce more leaves

• They take in more carbon dioxide

• They perform less photosynthesis

• They grow taller to reach the sunlight

The main function of photosynthesis is to produce food for the plant. However, something else happens during photosynthesis that supports animal life. Which part of the illustration shows the part of photosynthesis that is essential to animals, but is not related to food?

• the release of oxygen from the leaves

• the absorption of sunlight by the leaves

• the taking in of carbon dioxide by the leaves

• the production of glucose in the leaves

Why is sunlight so important to the process of photosynthesis?

• It transforms the carbon dioxide into oxygen that is released through the leaves

• It provides the needed temperatures to change glucose into water

• It provides the energy needed to combine the atoms in glucose

• It raises the levels of gases in the air so that water can change into oxygen

A student made the model of the carbon cycle seen in the diagram. She wanted to show how carbon moves through an ecosystem.

 

            How is carbon transformed during Process A?

• The plants take in oxygen from the atmosphere and convert it into  carbon dioxide

• The plants take in water from the atmosphere and release carbon compounds

• The plants take in carbon dioxide from the atmosphere and convert it  into glucose

• The plants change carbon compounds from the soil and release them into the air as carbon dioxide

Which of the following statements best explains if his results agree with the Law of Conservation of Mass?

• They do not, because mass should not be changing while he is stationary

• They do, because his mass stays consistent from test to test

• They do not, because this law does not apply to living organisms

• They do, because he exhales carbon dioxide through respiration during each test
