Biology Biogeochemical Cycles Test Study Guide Flashcards
(20 cards)
Matter Cycles through living and nonliving components of the ecosystem.
(Water, Carbon, Nitrogen)
Water, Carbon, and Nitrogen
Cannot happen without decomposers like bacteria.
Carbon and Nitrogen
Has stages that occur underground.
Water, Carbon, and Nitrogen
Matter takes different forms as it cycles.
Carbon and Nitrogen
Entire cycle is driven by the sun.
Water
When water returns to the atmosphere via plants.
Transpiration
A step in the Carbon cycle that didn’t really exist before the industrial revolution.
Combustion
When Nitrogen get captured from the atmospheres by bacteria or even lightning.
Nitrogen Fixation
Water is absorbed underground and can be stored in aquifers.
Infiltration
Water is not absorbed underground but collects on the surface of the earth.
Runoff
Fungi and bacteria return nutrients from dead organisms to the soil.
Decomposition
Bacteria in the roots of plants convert nitrogen into usable forms such as NO2.
Nitrification
Organism eat other organisms as a food source.
Consumption
Organisms capture sunlight and store the solar energy as a chemical energy in molecules like carbohydrates.
Photosynthesis
When nitrogen is returned to the atmosphere by bacteria as N2.
Denitrification
Water falls from the sky as snow, sleet, or rain.
Precipitation
When organisms breakdown carbon-based molecules for energy and release CO2 as a result.
Cellular Respiration
List an example of human impact of the water cycle.
Deforestation: Decrease in transpiration
List an example of human impact of the carbon cycle.
Combustion: Increase of CO2 (Carbon Dioxide) in the atmosphere
List an example of human impact of the nitrogen cycle.
Fertilizers: Increase of N (Nitrogen) in the soil creates an imbalance
