The Cycles Of Matter (Quiz)

Actinobacteria sp. are fermenting organisms (which do not use oxygen to breathe) referred to as chemoorganohetereotrophs. This means they break down organic material and convert it to inorganic material. Which part of the carbon cycle does this describe? A.) Photosynthesis B.) Respiration C.) Decomposition D.) Assimilation

Which of the following would be a result of eutrophication of nitrogen? A.) Undergrowth of water plants B. Hypoxia, or low levels of oxygen C.) Decreased decomposition D.) Inactivity of fertilizers

Plants use the process of _______________________ to remove carbon dioxide from the air.

Which are limiting nutrients for plant growth? A.) Water and nitrogen B.) Nitrogen and carbon C.) Carbon and phosphorus D.) Phosphorus and nitrogen

What is the name of the process that plants use to remove carbon from the atmosphere? A.) Transpiration B.) Photosynthesis C.) Respiration D.) Decomposition

Which statement best describes a human influence on the biogeochemical cycles? A.) Increased eutrophication caused by high levels of nitrogen and phosphorous B.) Increased nitrates available due to inaccurate methods of denitrification C.) Increased global warming due to alternative energy sources D.) Increased amount of water that is available to freshwater ecosystems

Which process allows water to enter the atmosphere? A.) Evaporation B.) Condensation C.) Precipitation D.) Freezing
