Water Flashcards
matter cannot created nor destroyed. It can only be transformed from one form to another.
• Law of conservation of mass states that
Therefore, matter cycles through the biosphere. It is called
biogeochemical cycle.
anything that takes up space and has mass –provides the nutrients needed for organisms to function.
Matter–
a chemical substance that an organism must obtain from its environment to sustain life and undergo life processes.
Nutrient–
Essential elements are stored in ?, places where elements are kept for long period of time
Reservoir
water in plants → water vapor
- Transpiration -
solid water to water vapor
S ublimation:
Water vapor condenses to form water droplets (clouds, fog, dew)
- Condensation –
Water droplets fall (rain, snow or ice/hail
. Precipitation –
. – Water vapor into ice (snow and frost)
Deposition:
the rate at which water enters a soil
- Infiltration:
The rate at which water moves through a soil
Percolation
flow of water to drainage basin or watershed
. Runoff:
Storage
It is the framework for all biomolecules.
Crbon
Plants take up carbon dioxide from the air and carry out photosynthesis. This is when carbon enters the land food webs.
Photosynthesis
Plants and all living things carry out aerobic respiration. Carbon returns to the atmosphere as carbon dioxide.
Cellular respi
Carbon diffuses between the atmosphere and the ocean. Carbon dioxide becomes bicarbonate when it dissolves in ocean water.
- Formation of bicarbonate ion (HCO3-).
Marine producers take up bicarbonate for use in photosynthesis, and marine organisms release carbon dioxide produced by aerobic respiration.
- Aquatic photosynthesis and cellular
respiration.
