Answer:
D. service
Explanation:
Most people in the US work in jobs that require providing a service to others, whether it's at a restaurant, a department store, a school, etc. Yet, those who work in specialised jobs like agriculture, fishing, and mining are more rare because they need to live in a certain area that is optimal for such positions.
Thus, the answer is D.
2nd choice is the correct one
No, and the environment also adds on to influencing traits.
Hope this helps. If not, I apologize.
Answer:
Nutrient
Explanation:
Ecology can be defined as the scientific study of the relationship between living organisms such as plants and animals in relation to their physical and biological environment.
Nutrient inputs to the system come from weathering of rocks, from windblown dust, and from precipitation, which can carry material great distances. Various amount of nutrients are transported or transfered from terrestrial ecosystems through erosion and then deposited in aquatic ecosystems such as oceans, seas, and associated lowlands.
Erosion can be defined as a geological process which typically involves the wearing out of earthen (soil) materials and the transportation of these materials by natural forces like water, wind, etc. Soil erosion is greatest when the soil is steep.
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
