Ecology Quiz

What is the purpose of creating a model tracking carbon atoms between inorganic and organic molecules in an ecosystem?

• To understand the reproductive cycles of plants

• To explain human impacts on climate

• To analyze the migration patterns of animals

• To study the effect of sunlight on photosynthesis

Why are biogeochemical cycles critical for ecosystem function?

• They help in the construction of ecosystems.

• They are critical for the cycling of matter in the biosphere.

• They decrease biomass in ecosystems.

• They represent the transfer of energy in mathematical models.

What is the purpose of analyzing examples of ecological succession?

• To understand the reproductive cycles of plants and animals

• To identify and explain the order of events responsible for the formation of a new ecosystem

• To study the effects of pollution on ecosystems

• To classify different types of plants and animals within an ecosystem

Which of the following best describes the role of decomposers in an ecosystem?

• They produce oxygen through photosynthesis.

• They consume primary producers.

12D: Students designed an experiment to model the carbon cycle. The students combined water and carbon dioxide-producing disks in a sealed flask. The flask represented Earth’s atmosphere, and the lamp represented the sun. Their design is shown. Which component can be added to the flask to reduce the concentration of carbon dioxide in the model atmosphere created by the disks?

• Bacteria to use carbon during nitrification

• Plants to absorb carbon in the process of photosynthesis

• Snails to use carbon through cellular respiration

• Mushrooms to absorb carbon during decomposition

What cycle is demonstrated in the diagram?

• The Carbon cycle
• The Water cycle
• The Nitrogen cycle
• The Life cycle

Animals inhale oxygen and exhale....
