5 0

Answer:

A. Nitrogen is the most abundant .

B. Oxygen is the most plentiful gas about 21% by volume.

Explanation:

Nitrogen is the most abundant  gas present in the atmosphere about 78 % by volume while the second most abundant gas is oxygen which is about 21 % in the atmosphere which is used by the living organism for breathing and energy production. Nitrogen is used by the plants for the production of amino acids and enzymes formation. Carbon-dioxide is present in a very low amount about 0.03 % in the atmosphere which is used by the plants during photosynthesis process.

Why would a vascular system be an adaptation for a plant on land?
Olin [163]

Answer:

Vascular have a system that is intricate and the plant can move water to distribute it to the whole plant. Vascular plants are able to grow bigger due to this ability. Example of this would be a tree or a flower Non vascular plants are usually small plants that are close to the ground.

Explanation:

Bryophytes, which evolutionarily precede tracheophytes, are plants that lack true vascular tissues by which to circulate liquids. These plants include mosses, hornworts and liverworts. Tracheophytes, which comprise about 93 percent of all land plants, all possess vascular systems that permit the internal circulation of liquids and nutrients.

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.
