when water vapor turns into liquid water

What is condensation?

100

Gas that makes up about 78% of the Earth's atmosphere.

What is Nitrogen?

100

the main source of phosphorus in ecosystems

What are rocks and minerals?

100

Process plants use to convert carbon dioxide into glucose.

What is photosynthesis?

100

process plants perform that releases oxygen into the atmosphere

What is photosynthesis?

200

This is the stage in the hydrologic cycle when water is released by plants from their leaves.

What is transpiration?

200

the process by which nitrogen is converted from the atmosphere into a form usable by plants

What is nitrogen-fixation?

200

Describe how phosphorus is released into the soil from rocks

What is through weathering?

200

These are ways carbon is released back into the atmosphere.

What are through respiration, burning fossil fuels, and air pollution?

200

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?

300

This is the main source of energy that drives the hydrologic cycle

What is the sun?

300

Name one human activity that affects the nitrogen cycle.

What are agricultural fertilizers, burning fossil fuels, and deforestation?

300

Phosphorus is important to living things because of this.

What is it is necessary for DNA, RNA and ATP?

300

These are roles of fossil fuels in the carbon cycle.

What is burning fossil fuels contributes excess CO2 to the atmosphere?

300

A major source of oxygen in the environment is this.

What are green plants in forests and photosynthetic algae and bacteria?

400

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.

400

Describe the role of bacteria in the nitrogen cycle.

What is bacteria convert atmospheric nitrogen into ammonia and nitrates, which plants can use? 

400

How plants acquire phosphorus from the soil

What is through absorption from the soil?

400

This is the impact of deforestation on the environment.

What is deforestation reduces the amount of trees to absorb CO2 from the atmosphere?

400

Oygen is cycled by animals through these steps.

What is animals consume oxygen for respriation and release CO2 into the atmosphere?

500

 Explain the importance of the hydrologic cycle to ecosystems.

The hydrologic cycle is crucial for water availability, influencing weather patterns, and supporting ecosystems.

500

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?

500

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?

500

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?

500

Expain how the oxygen cycle is important.

What is it is necessary for sustaining life?
