Hydrologic Cycle
when water vapor turns into liquid water
What is condensation?
Gas that makes up about 78% of the Earth's atmosphere.
What is Nitrogen?
the main source of phosphorus in ecosystems
What are rocks and minerals?
Process plants use to convert carbon dioxide into glucose.
What is photosynthesis?
process plants perform that releases oxygen into the atmosphere
What is photosynthesis?
This is the stage in the hydrologic cycle when water is released by plants from their leaves.
What is transpiration?
the process by which nitrogen is converted from the atmosphere into a form usable by plants
What is nitrogen-fixation?
Describe how phosphorus is released into the soil from rocks
What is through weathering?
These are ways carbon is released back into the atmosphere.
What are through respiration, burning fossil fuels, and air pollution?
The relationship between photosynthesis and the oxygen cycle is this.
What is photosynthesis produces the oxygen in the atmosphere that is used to undergo cellular respiration?
This is the main source of energy that drives the hydrologic cycle
What is the sun?
Name one human activity that affects the nitrogen cycle.
What are agricultural fertilizers, burning fossil fuels, and deforestation?
Phosphorus is important to living things because of this.
What is it is necessary for DNA, RNA and ATP?
These are roles of fossil fuels in the carbon cycle.
What is burning fossil fuels contributes excess CO2 to the atmosphere?
A major source of oxygen in the environment is this.
What are green plants in forests and photosynthetic algae and bacteria?
Describe how water moves from the ground to the atmosphere in the hydrologic cycle.
Through evaporation and transpiration, water vapor rises into the atmosphere and eventually cools and condenses into clouds.
Describe the role of bacteria in the nitrogen cycle.
What is bacteria convert atmospheric nitrogen into ammonia and nitrates, which plants can use?
How plants acquire phosphorus from the soil
What is through absorption from the soil?
This is the impact of deforestation on the environment.
What is deforestation reduces the amount of trees to absorb CO2 from the atmosphere?
Oygen is cycled by animals through these steps.
What is animals consume oxygen for respriation and release CO2 into the atmosphere?
Explain the importance of the hydrologic cycle to ecosystems.
The hydrologic cycle is crucial for water availability, influencing weather patterns, and supporting ecosystems.
Explain how the nitrogen cycle is essential for plant growth.
What is Nitrogen is a vital nutrient for plants, as it is a key component of amino acids and proteins?
This explains how human activities disrupt the phosphorus cycle.
What are activities such as agriculture and wastewater discharge lead to eutrophication and disrupt the cycle?
Discuss how the carbon cycle relates to climate change.
What is excess carbon dioxide and carbon monoxide in the atmosphere contribute to the amount of green house gases that keep the planet warner than usual?
Expain how the oxygen cycle is important.
What is it is necessary for sustaining life?
