Elements like Carbon and Oxygen move throughout the ecosystem in a…
Cyclic Pattern
Nitrates are added by;
- Nitrogen Fixing Plants
- Fertilizers/ Compost/ Manure
- Lightining
Nitrates are taken away by;
- Bacteria
- Water carries away nitrates
- Harvesting Plants
Nitrates are taken away by;
- Bacteria
- Water carries away nitrates
- Harvesting Plants
Natural Processes;
- Chemical Cycles- cycling of elements and compounds
- Cellular Respiration- Food chemicals and oxygen are used to make the body energy
Define Agricultural Activities
Farmers use chemicals to help control the growth of their crops
What do the numbers on a fertilizer bag stand for
20-20-20
Nitrogen-Phosphate-Potash
(N,P,K)
Define Crop Rotation
Crops tha t are nitrogen fixing increase soil nitrates
Define Organic Foods
Are grown in sn environment free of pesticides
Define Solid Wastes
The garbage from homes and industry that cannot be recycled is put into landfills
Define Wastewater/ Sewage
Water containing dissolved and undissolved materials is carried by pipes to septic tanks
Define Septic Tank
The underground container where bacteria break down organic materials before they are moved out into the soil
Define Sewage Treatment Plant
Treats wastewater from homes and industry and releases it ( called EFFLUENT)
Define Storm Sewers
Collects street water
Define Fuel Combustion
Oxygen is used to burn fossil fuels and energy is released
