You create a hybrid with two crops at one time (2 parents for sexual reproduction).
The offspring of the hybrid can then be bred with a third crop, or even another hybrid.
Presumably with genetic manipulation, genes could be taken from more than 2 parents, but one typically only has 2 sets of chromosomes.
See wikipedia article on types of Hybrids.
No, a 100W lamp will consume more energy than two 60W lamps. The total power consumption of two 60W lamps would be 120W, which is more than the 100W lamp.
Two is more stronger themselves
Perennials are the plants that live for more than two growing seasons.
Angiosperms that live for more than two years are calledperennials.
Many of the planets have more than one element. Two of these planets that have more than one element are Earth and Jupiter.
species
No. The two species are from different families, and are too genetically diverse to hybridize.
intercropping is the practice of growing two or more crops in proximity.
The disadvantages of an economy based on one or two cash crops is that if those crops fail, the economy fails. Most countries and areas have quite a few crops they grow which leads to a more stable economy.
Wheat and spelt were two important crops.
No. The blood orange and satsuma are two different species. (Though they can sometimes hybridize) The blood orange has dark red flesh, the satsuma light orange. The satsuma is also tarter than the blood orange.
No, three is more than two.
Two main reasons: 1) Crops and livestock tend to be mutually beneficial. The crops feed the livestock, and the livestock waste feeds the crops. 2) The more diverse a farm is, the more protected the business is from changes in the market. If a farm only produces one or two crops, the farm is at much greater financial risk from a downturn in the market, whereas it is much less likely that four or more products will all be down in the market at the same time.

A composite number has more than two factors.
corn,wheat,barley,oats and more but i don't know
If by "has more than two whole numbers" you mean more than two factors, the answer is all composite integers.
