There is no or little farming in much or North Africa along with southern Africa because of the climate. It's getting farther away from the equator and the climate starts to get colder.
Most of North Africa is covered by the Sahara desert.
They are the people who live in North Africa. The majority of them are Nomads and a few are Muslims.
Algiers, Algeria
The desert receives little rainfall and plants have to compete for what little falls. They grow a distance for their neighbors to avoid competition and have a better chance of surviving.
Perhaps the question should have been ..could it grow in South Africa? It is indeed possible that ragweed could grow in South Africa if someone brought it into the country either by accident or otherwise. Its growth would depend upon the region as it tends to be found in temperate climate zones of which there are a few in South Africa that mimic same at least for part of the year.....i.e. areas of The Free State and KZN (Howick)
why are there so few ancient ruins in Africa
Few plants survive in a desert because the climate is too dry.Because there isn't enough water or moisture in the soil for plants to take up through their roots so normal plants can't survive in the desert.
Few plants grow tall on the forest floor because there is a lack of sunlight.
There are few plants and animals hardy enough to survive in the Sahara’s arid climate.
dessert
There are a few plants that grow better with morning sunlight. Some of the plants are spring bloomers, pansy and sunflowers.
There can be more plants. But very few people know it.
nonvascular plants
The venus fly trap grows in a small region in North and South Carolina. There are few plants left in the wild, and are considered threatened.
There are quite a few plants that grow in low moisture climates. These plants will typically have very thick protective tissues.
A desert
There are quite a few plants that are fun to grow. Marigolds, nasturtiums, peas, beansprouts, and mustard are all easy and fun to grow from seeds. You can even grow a plant from a carrot top.
Few plants grow in the waters of a swift-flowing stream because the water's movement makes it tough for the plants to attach to any surfaces. Often, plants are pushed to the tidal pools or the mouth of the streams.
