Put the following in order of introduction of fertilizer into the water cycle
Rain water washes fertilizer from farmland into rivers and lakes!
Aquatic plants and algae will grow quickly. The algae on the surface of the water restricts light energy from the sun from reaching the bottom of the river or lake!
The plants at the bottom of the lake cannot photosynthesize and therefore die! Bacteria increase decomposition due to the high population of plant death!
Microbes use dissolved oxygen in the water to go through cellular respiration! Therefore, the level of oxygen in the water decreases!
As the oxygen levels in the water lower, aquatic animals can suffocate and die! Thus, decreasing the number of species populations in natural ecosystems!
The process that occurs when water changes from a liquid to a gas caused by heat!
Evaporation
The cooling of water in the atmosphere changing gas to a liquid
Condensation
water droplets fall from the atmosphere in the form of rain, sleet, snow or hail.
Precipitation
That passage of water vapor from a plant to the atmosphere.
Transpiration
water that has saturated the soil, mineralized, and is a store of water that slowly moves toward the ocean.
Groundwater

The model is part of the carbon cycle. What type of organisms would be in box A?
plant
animal
virus
humans
Carbon cycles through the ecosystem through which two main processes? Select all that apply.
Plants performing evaporation
Plants performing photosynthesis
Animals performing cellular respiration
Animals performing transpiration
The model is part of the carbon cycle. What is the process in box B in the diagram?
cellular respiration
fermentation
anaerobic respiration
photosynthesis
Calculate the net change of carbon atoms going into and out of the atmosphere to answer the following question. What impact will this change have on the atmosphere?
Carbon dioxide is a greenhouse gas that releases heat to outer space, cooling the atmosphere. The increase of CO2 is making the atmosphere cooler.
Carbon dioxide is a greenhouse gas that traps and holds heat, warming the atmosphere. The increase of CO2 is making the atmosphere warmer.
Carbon dioxide is a greenhouse gas that releases heat to outer space, cooling the atmosphere. The decrease of CO2 is making the atmosphere cooler.
Carbon dioxide is a greenhouse gas that traps and holds heat, warming the atmosphere. The decrease of CO2 is making the atmosphere warmer.
During a forest fire, most of the carbon in a tree is released into which reservoir?
biosphere
geosphere
hydrosphere
Atmosphere
There is scientific evidence from ice cores showing that the concentration of carbon dioxide in the atmosphere is more now than it was several hundred years ago. Many scientists hypothesize that the increase in concentration is due to the burning of fossil fuels. Which of the following best explains the increases in carbon in the atmosphere?
Carbon that was removed from the atmosphere because of photosynthesis is released back into the atmosphere because of respiration
Carbon stays in the fossil fuel during combustion and causes the atmosphere to maintain its concentration of carbon dioxide.
Carbon that was stored in trees is released into the atmosphere during a forest fire.
Carbon that was not part of the normal cycle because it was trapped in fossil fuels buried in the ground became released into the atmosphere when a fossil fuel was burned.
