In what cycle is photosynthesis by plants and algae the primary way that carbon is removed from the atmosphere?
What is the carbon cycle?
What is the water cycle?
Nitrogen is an element needed to build proteins of
the dirt, living things, only humans, or air
What is all living things?
Brings phosphorus into our waterways.
Precipitation, fertilizer runoff, transpiration, or condensation
What is fertilizer runoff?
This predator is the consumer at the top of the food chain.
During respiration oxygen is consumed and what is released?
nitrogen, carbon dioxide, oxygen, or waste
What is carbon dioxide?
When a plant releases water vapor into the air
condensation, evaporation, precipitation, or transpiration
What is transpiration?
Nitrogen makes up how much of the atmosphere?
100%, 25%, 38%, or 78%
What is 78%?
Decomposers return phosphorus into the soil in what cycle?
What is the phosphorus cycle?
Producers such as grass release what gas into the atmosphere
What is oxygen?
Which two organism released carbon from waste and dead organisms back into the environment?
fungi, bacteria, horses
What is fungi and bacteria?
Maintaining this is important to keep an ecosystem healthy.
water levels, biodiversity, oxygen levels, or geodiversity
What is biodiversity?
The process is how plants get nitrogen and absorbs it from soil into roots
fixation, nitrification, assimilation, or bacteria
What is assimilation?
Most mined phosphorus is used to make
rock, salt, fertilizer, or food
What is fertilizer?
Animals and humans release what gas into the atmosphere
What is carbon dioxide?
How is energy released from food in most animals?
What is respiration?
What would happen if the Sun is removed from the water cycle?
The water cycle would not exist due to:
no precipitation, no evaporation & transpiration, or no formation of clouds
What is no evaporation & transpiration?
Some species are more important to an ecosystem than others. The are called what kind of species?
extinct, endangered, keystone, or apex
What is keystone?
Phosphorous is needed in organisms for the production of all these EXCEPT...
ATP, Cell Membranes, DNA, Oxygen sources
What is Oxygen sources?
The flathead catfish is an invasive predatory species fish. What would be the effect of the introduction of the flathead catfish on the native fish in the rivers of the United States?
What is population decrease?
The trees absorb what type of gas from the atmosphere in order to generate oxygen gas?
What is carbon dioxide?
Plants use water, carbon dioxide, and what else to make food?
oxygen, light, or soil
What is light?
This is not a process of the nitrogen cycle:
nitrogen fixation, nitrification, assimilation, or bacteria
What is bacteria?
Too much phosphorus in waterways (rivers, lakes, etc...) can lead to...
Massive algal blooms, erosion, decomposition, or diseases
What is massive algal blooms?
What is the name of the organisms that break down dead matter in an ecosystem?
