It erodes

Inorganic phosphate

Taken up by roots of plants and incorporated into tissues

Heterotrophs

Eat plants and drink water

Extraction and decomposition

Releases phosphorus into soil

Where can it be stored?

In rock sediment

Use fertilizer, flush waste, clear cutting

Phosphate ions are absorbed by plant roots and used to build two organic molecules like?

ATP and DNA

Low phosphorus levels in freshwater lakes limits the overgrown of what?

Algae

An excessive increase in phosphorus, or other nutrients is called?

Euthrophication

Phosphorus Cycle

The movement of phosphorus atoms from rocks through the biosphere and hydrosphere and back to rocks.

Photosynthesis, cellular respiration

_____ and cellular respiration are the 2 main biotic processes of the carbon cycle.

cellular respiration

What is process 4?

Combustion

What process adds carbon to the atmosphere (in the form of CO2)?

CO2

Carbon (in the form of _____) is removed from the atmosphere by producers that do photosynthesis.

Photosynthesis

____ removes CO2 from the atmosphere. This is only done by autotrophs.

photosynthesis

What is process 2?

Consumption

What is process 5?

decomposition

What is process 7?

combustion (burning of fossil fuels)

What is process 1?

decomposition

What is process 6?

fossil fuels

formed by process 9

O2

molecular formula for oxygen gas

CO2

molecular formula for carbon dioxide

CO2

gas made by cellular respiration

O2

gas made by photosynthesis

greenhouse gases

gases in the atmosphere that trap heat (eg. water vapour, carbon dioxide, methane..)

Abiotic

Non-living

Biotic

Living

Exchange

Carbon released from the ocean into the air or from the air to the ocean.

Sedimentation

Carbon dioxide dissolved in ocean combines with calcium ions in water to form calcium carbonate.

extraction

Taking up the carbon that is buried within in the Earth

Nitrogen

An important element needed by living things.

Nitrogen is needed to build proteins.

Nitrogen is a key component in DNA (body's genetic program for life)

Nitrogen Cycle

The cycling of nitrogen between organisms, soil, water, and the atmosphere (Earth's spheres)

Nitrogen gas (N2)

78% of the atmosphere is made of nitrogen gas.

Plants and animals cannot get the nitrogen they need in this form.

Nitrogen Fixation

Process of converting nitrogen gas into nitrogen compounds, which are a usable form of nitrogen that plants can use.

Certain types of Bacteria and also Lightning can turn nitrogen gas into nitrogen compounds.

Lightning

converts nitrogen gas from the air into a usable form of nitrogen plants can use.

Denitrification

Process of converting nitrogen compounds into nitrogen gas, which is then released into the atmosphere.

Denitrifying bacteria carry out the process of denitrification.

Decomposition

A chemical reaction that breaks down compounds into simpler products.

When plants and animals decompose, nitrogen compounds are returned to the soil.

Bacteria

Microscopic living organisms that play an important role in the nitrogen cycle.

Nitrogen fixing bacteria change nitrogen gas to nitrogen compounds plants can use.

Denitrifying bacteria change nitrogen compounds to nitrogen gas to release back into the atmosphere.

Animals

Animals, including humans, get the nitrogen they need by eating plants or other animals that contain nitrogen.

When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water.

Animals also release nitrogen through their animal waste.

Plants

Plants take in the nitrogen they need through their roots. The nitrogen has to be "fixed" in a usable form.

Some plants (legumes) contain nitrogen fixing bacteria that live on their roots. The bacteria change nitrogen gas into nitrogen compounds the plants can use.

Soil

Nitrogen Compounds are found in the soil.

Nitrogen fixing bacteria change nitrogen gas to nitrogen compounds in the soil.

Denitrifying bacteria change nitrogen compounds in the soil to nitrogen gas.

Decomposers break down dead plants and animals and return the nitrogen to the soil.

Water Cycle

the process of recycling water

Evaporation

liquid water changes to gas

Condensation

gas changes to liquid

Precipitation

water falling from the sky

Transpiration

water from plants evaporating

Run off

water that flows along the ground returning to rivers, ponds, lakes, and oceans.

Ground Water

the water that gets absorbed and collect by the ground

Collection

places where water collects and then gets evaporated. Includes lakes, ponds, seas, and oceans.

Water Vapor

the gaseous form of water

Radiation

a type of heat energy from the sun that is responsible for heating and evaporating water from bodies of water

Water Droplet

a droplet of water

Snow

a type of solid precipitation

Rain

a type of liquid precipitation
