Seasonal Cycles
A regular, repeating pattern of change
What is a cycle?
The Earth system that includes all of Earth's water
What is the hydrosphere?
The movement of carbon between the atmosphere, the earth, and organisms
What is the carbon cycle?
The movement of nitrogen compounds between the atmosphere, the earth, and organisms
What is the nitrogen cycle?
This stress does not have a definite beginning or ending
What is a drought?
A person who studies plants and animals that live in or near the water
What is an aquatic ecologist?
God uses regular cycles of change to do this
What is maintain His earth?
When liquid water is changed to water vapor, or gas
What is evaporation?
Cellular respiration adds this to the atmosphere, and photosynthesis removes it from the atmosphere
What is carbon dioxide?
This gas makes up most of the Earth's atmosphere
What is nitrogen?
Between drought and flood, this is more likely to cause fires
What is a drought?
A type of organism that no longer exists
What is extinct?
The average temperature throughout the year changes according to these
What are seasons?
Precipitation can fall as both of these states of matter
What are liquid and solid?
These help break down wastes and bodies of dead organisms, which releases carbon back into the atmosphere
This forms most of the usable compounds from nitrogen gas
What is bacteria?
What is habitat destruction?
What is endangered?
Winds that blow across water and land, creating wet and dry seasons
What are monsoons?
When water vapor is released from plant leaves through the stomata
What is transpiration?
During cellular respiration, cells use oxygen for this
What is breaking down sugar into usable energy?
This changes a small amount of nitrogen gas into usable compounds, which are then carried to the earth by rain
What is lightning?
A series of gradual changes in the populations of organisms in an ecosystem; can be caused by natural or man-made stresses
What is succession?
An organism is this if its population could become endangered soon
What is threatened?
What is precipitation?
During these two processes of the water cycle, the state of matter changes from a liquid to a gas
What are evaporation and transpiration?
What are water, carbon dioxide, and energy from the sun?
Decomposers are part of the nitrogen cycle because they return this back to soil for plants
What are nitrogen compounds?
This is one way that a natural stress can benefit an ecosystem
What is it can put an ecosystem back into balance?
OR
What is by recycling nutrients into the soil?
An organism that has been introduced to a new ecosystem and can cause harm
What is an invasive organism?
