Answer:
the answer is volcanoes
Explanation:
The oceanic crust collides with the continental crust to form a convergent boundary. At the convergent boundary, the denser oceanic crust sinks under the lighter continental crust. The rocks of the oceanic crust reach very high temperatures of about 12,000°C, which is enough to melt the rocks. These molten rocks travel upward through cracks and crevices in the continental crust. They then erupt on the surface as volcanoes. Therefore, the feature expected to form at point X as the result of converging plates would be volcanoes.
Competition help to regulate population growth since only those who are able to obtain food survive.
Crop plants and weeds may compete for water and for sunlight.
Farmers spray herbicides early in the growing season to avoid competition between crop plants and weeds.
<h3>What is the effect of competition on population?</h3>
Competition among species help to regulate population growth by ensuring that only those who are able to obtain food survive. Thus, only fit individuals of a species survive.
Crop plants and weeds may compete for water because water enables them to carry out metabolic activities of growth and development.
Crop plants and weeds may also compete for sunlight and they need sunlight to carry out photosynthesis.
Farmers spray herbicides early in the growing season in order to avoid or reduce competition between crop plants and weeds.
In conclusion, competition among species helps to control overpopulation.
