Environmental Science Unit 4: Land Use & Human Impact 4. 3 I can compare the efficiency of different methods of food production.
Animals are farther up the food chain, therefore receive less energy
Plants provide more nutrients per gram
Meat is more expensive than vegetables, therefore it has more calories in it
Animals are always larger than plants, therefore always need more space
Rice, corn
Plants, animals

Soybeans, grains

Crop varieties
Soybeans
Pesticides
Sunlight
Crop rotation
Biological pest control
Composting waste
Genetically modified crops

Removing weeds by hand
Monoculture (planting only one crop variety on a plot of land)
Raising animals requires more nutrients from the soil
Animals require more energy, space, and resources to raise
Animal waste pollutes the land
Plants require more energy, space, and resources to grow
