Cycles of Matter

Biogeochemical Cycles

The cycling maintains homeostasis

(balance) in the environment as they

move from abiotic parts of an

ecosystem into biotic parts and back

again.

1. Water cycle

2. Carbon cycle

3. Nitrogen cycle

4. Phosphorus Cycle

All cycles change the matter

from one form to another

Water cycle-

•Water changes

through the

following
processes:
Evaporation,
transpiration,
condensation,
precipitation

Carbon cycle-

•Carbon cycles through out Earth and can be found

in the atmosphere, bodies of water, in rocks and

soil, in organisms and in fossil fuels

•All living things are organic, meaning they contain

carbon.

Nitrogen cycle-

The cycling of nitrogen which can be found in the
atmosphere, plants, animals and the soil. Nitrogen
is essential to form proteins and Nucleic Acids.

Lightning and bacteria convert nitrogen into usable
forms through Nitrogen Fixation.

Animals get useable nitrogen by eating plants

Phosphorus (P) Cycle

Component of DNA, RNA, ATP, proteins &
enzymes

- The source of Phosphorus (P) is rock.

- Phosphorus is released into the cycle

through erosion or mining.

-Phosphorus is taken up by plant roots,

then travels through food chains.
