Human Impact
What types of humans would be affected most if the Phosphorus cycle was gone. And why ??
Farmers, phosphorous is a fertiliser to help the crops grow.
The plants
True or false. Phosphorus helps animals build strong bones and teeth
true.
Why is the Phosphorus cycle important?
is important to life on Earth because it allows energy and matter to move between plants, animals, and the environment and for all living things to survive.
This human activity adds a large amount of phosphorus to the environment, through runoff and spreading of material.
what is agriculture and livestock operations.
is there such thing as too much phosphorus in water?
yes. Too much phosphorus in water causes rapid algae growth called an algal bloom.
why is Phosphate such an important nutrient on Earth
It connects plants, animals, and the environment in a continuous system that supports life. All living things need this cycle to survive
Name 3 important roles the phosphorus cycle has/does.
keeps O2 and CO2 balanced in the atmosphere
provides energy for living things
It connects plants, animals, and the environment in a continuous system that supports life
or anything else that would count*
Is phosphorus in water the same as the phosphorus found in rocks?
Yes it is regardless of being in different forms.
This can happen to fish and aquatic life when algae use up oxygen in the water.
What is fish death/oxygen depletion (dead zones)? This occur when dissolved oxygen levels in a body of water drop so low that aquatic life can no longer breathe
Phosphorus is needed for BLANK and BLANK which controls growth and cell function.
DNA and RNA. This is also known as ribonucleic acid. Nucleic acids that store and transfer the genetic information required for life.
This group of organisms breaks down dead plants and animals and recycles phosphorus
What are decomposers? Decomposers are organisms that break down dead plants, animals, and waste materials into simpler inorganic nutrients.
why does phosphorus drive crop growth by acting as the backbone for energy storage
Because phosphorus is a primary plant macro-nutrient
excess phosphorus in waterways can upset ecosystems by causing algae blooms that block the sunlight and reduce this important gas needed by fish and other aquatic organisms.
What is oxygen?
True or False: The Photosynthesis cycle needs phosphate to thrive
True
Phosphorus helps a healthy photosynthesis and overall plant development
Unlike the carbon and nitrogen cycle, the phosphorous cycle does not normally include this part of the Earth
It does not include the atmosphere
When excess phosphorus causes rapid algae growth in water, it is called this.
What is eutrophication? It is the process by which a body of water becomes overly enriched with nutrients (like nitrogen and phosphorus).
Explain one major way humans affect the phosphorus cycle and one environmental consequence.
Humans add excess phosphorus through fertilizers, sewage, or mining, which can cause eutrophication, algal blooms, and oxygen loss in water ecosystems.
This type of consumer obtains phosphorus directly from plants.
What is a primary consumer/herbivore?
This household product used to contain high amounts of phosphorus before regulations limited it.
what are detergents? (example laundry detergents)
