How does nutrient cycle work
The nutrient cycle involves the movement of essential elements like carbon, nitrogen, and phosphorus through plants, animals, and decomposers, ensuring nutrients are recycled and available for new growth.
what happens when something wring happens in the cycle
global warming
If there is too much evaporation or not enough precipitation (due to climate change), it can cause droughts
- What happens when the farmer uses fertiliser with massive amounts of nitrogen in it WAH
Water Pollution – Extra nitrogen washes into rivers and lakes, causing eutrophication,
Air Pollution – Excess nitrogen can be released as nitrous oxide a greenhouse gas that contributes to global warming
Harm to Plants and Animals – High nitrogen levels can burn plant roots
- What happens if the carbon cycle if we release massive amounts of carbon dioxide or methane GOD
Global Warming – CO₂ and Methane are greenhouse gases that trap heat in the atmosphere
Ocean Acidification – Excess CO₂ dissolves in seawater, forming carbonic acid
Disruption of Ecosystems – Higher temperatures and changing weather patterns
NITROGEN CYCLE————————————————————————————- NNAAD
Nitrogen fixation
Nitrates
Assimilation
Ammonification
Denitrification
STEP 1 Nitrogen fixation
Turn into a form that can dissolve in water, and that form is called ammonia
STEP 2 Nitrates
is what a plant wants (ammonia converts into nitrates bacteria)
STEP 3 Assimilation
Nitrates absorbed by the plants --------(food chain)
STEP 4 Ammonification
Nitrogen is now form of protein and DNA they live there lives and they die into soil and the bacteria break them down as ammonia
STEP 5 Denitrification
Ammonia turns into nitrogen gas by denitrifying bacteria and released into the atmosphere
Eutrophication
Nitrogen gets into water and the plants grow and use up all the oxygen and they end up dying
Why we need bacteria
nitro bacteria help convert nitrogen gas from the air into forms that plants can use, such as nitrates and ammonium.
Other bacteria break down dead plants and animals, returning nutrients to the soil through decomposition.
Why nitrogen gas is problem
Excess nitrogen in the atmosphere can produce pollutants such as nitrogen oxides, which contribute to the formation of ozone and particulate matter. These pollutants can impair respiratory health, reduce air quality, limit visibility, and disrupt plant growth by altering nutrient balances.
Where is nitrogen useful KFNHE
key part of proteins, which help build muscles and tissues in animals,
found in DNA, which carries genetic information. In plants
nitrogen makes chlorophyll, the green pigment that allows them to absorb sunlight for photosynthesis.
helps plants grow strong and healthy by supporting the formation of new cells.
ensuring that plants and animals have the nutrients they need to survive.
Why plants need nitrogen
Nitrogen is a key element in making proteins, which help build plant cells and tissues. It is also needed to produce chlorophyll, the green pigment that allows plants to carry out photosynthesis and make their own food.
CARBON CYCLE rpcdo—————————————————————————————
RESPIRATION
PHOTOSYNTHESIS
COMBUSTION
DECOMPOSITION
OCEAN
Respiration ⬆CO2
returns carbon in the form of CO2 back into the atmosphere
- Sugar+ oxygen = carbon dioxide+ water+ energy
Photosynthesis ⬇CO2
- Plants take in carbon dioxide from the atmosphere released as respiration
- Carbon dioxide + water+ sunlight = sugar + oxygen
COMBUSTION ⬆CO2
Fuel burns in oxygen releases carbon dioxide
Occurs when a substance and oxygen gas react to release heat and light energy
DECOMPOSITION ⬆CO2
- Living things die, decomposition breaks down releases carbon dioxide into the atmosphere
OCEANS ⬇CO2
CO2 absorbed and stored in the ocean
what is a nutrient cycle
- New elements cannot be recycled and nutrients are limited in supply
Biogeochemical cycle
nothing new can be added, and nothing can be taken away, resources such as nutrients must be recycled so they can be reused
what is nitrogen the building blocks of
- building blocks of proteins and nucleic acids such as DNA
Why ammonia is problem
Health Risks: Ammonia irritates the respiratory system and worsens asthma.
Water Pollution: Toxic to aquatic life and contributes to eutrophication.
Soil Acidification: Can harm plant growth and reduce biodiversity.
Nitrogen Overload: Excess nitrogen disrupts ecosystems and agriculture.
Movement of carbon
transfer of carbon between the atmosphere, oceans, land, and living organisms.
why is too much carbon dioxide bad
Extreme Weather – More droughts, storms, and heatwaves. (because of climate change)
Ocean acidification: Acidic waters harm marine life like coral reefs, shellfish, and plankton, disrupting food chains.
how has carbon dioxide increased DAGOE
Through the burning of fossil fuels
Deforestation – Reduces forests that absorb CO₂.
Agriculture – Contributes through soil disturbance and livestock.
Global Warming – CO₂ traps heat, causing rising temperatures.
Ocean Acidification – Oceans absorb CO₂, making them more acidic.
Whats carbon dioxide
Carbon dioxide is a greenhouse gas, it forms a layer around the earth keeping heat in. Radiation from the sun enters the atmosphere bounces off the surface and is trapped by the carbon dioxide.
Enhanced greenhouse effect
- CO2 levels are too high
- Too much heat trapped
- Global temperatures increase
Why do we care about climate change
- Rising sea level = flooding, more droughts and wildfires, changes in plant life cycle
- The weather gets worse because global weather patterns are getting messed up
why too much nitrogen bad
Air Pollution: Nitrogen oxides create smog and ozone, harming health.
Water Pollution: Nitrates contaminate drinking water, causing health risks.
Eutrophication: Excess nitrogen causes algae blooms, depleting oxygen in water.
Soil Acidification: Nitrogen overload harms plant growth and biodiversity.
Difference between carbon and carbon dioxide
Carbon is an element and carbon dioxide is a compound which is made up of elements of carbon and oxygen
why plants need nitrated and ammonia
