What environmental factors have the greatest effect on determining regions for crop production?

ANSWER:

The environmental factors that affect determination of regions of crop production are terrain, soil, water and climate.

EXPLANATION:

Crops need proper water and climate so that they can grow in the required manner. They also need fertile soil for their growth. The terrain of the land determines the types of crops that can be grown in a region.

For instance, in plains, the soil is fertile and water is easily available for crops. In addition, the climatic conditions of plains allow the growth of crops like rice.  

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
