Fill in the blank:
astra-53 [7]

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.

Describe how each of Newton’s laws may be observable during a car trip.
aleksandrvk [35]
According to Newton's first law, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Any passengers in the car will also be decelerated to rest if they are strapped to the car by seat belts. Also if a car was going straight but another car (unbalanced force) bumps into it causing the motion of the car to change.
