Problems With Overgrazing

1 answer:

4 0

The weak, overgrazed pasture will be particularly vulnerable to interrill, rill, and gully erosion, which can result in the loss of important topsoil, a decrease in soil organic matter, and a drop in the nitrogen pool available to feed your fodder. Compaction of the soil is exacerbated by excessive grazing.

Goshia [24]

Sean, who weighs the least of the three, will have the highest blood alcohol concentration (BAC).

The less a person weighs, the more they will be affected by a given amount of alcohol. People of the same weight, even the same gender, individuals with a lower percentage of body fat will have lower blood alcohol concentration than those with a higher percentage of body fat.

Hope this helps! :)

Give the role of air in an ecosystem

Radda [10]

Sustain Life and Growth

Air consists one of the main life-sustaining gas called oxygen. Almost all living things breathe in and breathe out this air. Nitrogen and Carbon dioxide are also other gases that are vital for plants and their growth.

Combustion

Apart from this, air supports burning or combustion. The oxygen present in air help in burning of the fuels to basically carry out activities like cooking food, running industries and vehicles as well as generating heat and electricity.

Temperature Control

Another important aspect of air is that it helps in maintaining the temperature on the earth surface by circulating hot and cold air. Air acts as a conductor of heat as well. Even phenomena such as water cycle are dependent on air.

Supplier of Energy

Air which consists of energy is one of the main suppliers of energy. Living things are made up of cells and these cells extract oxygen within the blood to produce energy usually in the form of ATP. This biochemical generation of ATP is essential to maintain life on the earth.

Photosynthesis

Carbon dioxide, which is a component of air is used by plants during the process of photosynthesis. Here oxygen is also released by plants. And we already know how vital oxygen is.

Which part of the cell theory do these results most support:

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2>

$\huge\textbf{Cell Theory}$

the Cell Theory was give by German scientists, Schleiden and T.Shwan in 1839. It stated that,

All organism are composed of one or more cells

The cell is the structural and functional unit of life
It is a de novo structure, that means it COULD arise from non living thing which was incorrect.

It was corrected by the German pathologist Rudolf Virchow in 1855. He made a convincing case, corrected and added the third point of the cell theory. It is,

Cells can arise only by a division of pre-existing cell. It is <u>NOT</u> a de novo structure.

Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.

$\huge\textbf{Question:}$

<u>Flask 1</u>: It is observed that there are no micro-organism, this is because the meat is sealed and no micro-organism could enter through it.
<u>Flask 2</u>: It is observed that there are micro-organism present because meat is not sealed but open.
<u>Flask 3</u>: As the S tube is used, the micro-organism are not able to reach the meat because of the curvy path

These observations support the point that<u> cells could arise only by a division of pre-existing alive cells</u> because in Flask 1 when there were no micro-organism present so there was no organisms found so no micro-organism arised, In flask 3 the S tube was used so no micro-organism could reach the meat thus there were no organism there which could divide to reproduce. The flask 2 was open, so the micro organisms reached the meat so they divided which means Cells can only arise by a division of pre-existing cells.
