When the moon is in the middle of earth and the sun.
An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system. <span>

<span>The biogeochemical cycles move through mainly the biotic and abiotic components of the earth, more elaborately the spheres -biospheres, lithosphere, hydrosphere and atmosphere regions of the ecosystem. These biogeochemical cycles, from its terminology and discernable word morphology- involves the biological, geological and chemical components that make out to complete an exact and purposed cycle. The purpose in these cycles are to maintain balance and to ensure the ongoing process of the living and non-living organisms in the environment. These cycles’ help to living organisms survive and thrive. One popular example is the water cycle.

Answer:
The Quebec-City-Windsor Corridor
Explanation:
The population density of Canada is 4 people/km².
The most densely-populated urban areas are Vancouver and Montreal (4800/km²).
The most densely populated region of Canada (80/km²) is the Quebec-City-Windsor Corridor. It contains almost half the population of Canada.
There are two main reasons for this.
(a) Climate
The region is entirely below the 47th parallel, so the summers are warm, the winters are not harsh, and the area is suitable for agriculture.
(b) Location
The corridor is close to the border with the United States and carries the bulk of Canada's trade with them. It makes sense for people to live as close to the US border as possible.
