Answer:

So where then did all the carbon that living organisms are built of come from? It turns out that most of the carbon we use today came from a collision with another smallish planet about 4.4 billion years ago.

In Alaska, grizzly bears must eat 10 fish and drink up to 25 liters of water to live. A
EleoNora [17]

The fish is the limiting factor because its population <u>determines the survival and availability  of the grizzly bears.</u>

A limiting factor is  resources(biotic or abiotic) that affects or determine the availabity and growth of an organism or group of an organism within an ecosystem.

The more fish it takes, the more the liver produces urea, and kidney tubules  makes use of the urea in it tubules for urine formation in the loop of Henle. The urine formation and loss, leads to intake of water and the sequence continues.

This is an example of a biological limiting factor because the bear  predate on the fish for survival and population.

If the population of the fish drops,( <u>the limiting facto</u>r) the bear drinks less water based on above, and therefore <u>disruptions  of the ecosystem</u>.

explain : in order to get rid of any effects of agricultural insecticides in the fruits, it is advised to soak them in a diluted
Vedmedyk [2.9K]

As we have studied in junior classes <em>that all animals including bacteria contain a plasma membrane around their cell which controls the movement of water and materials to and from the cell.</em>

The bacteria are the main hazard in pesticides and if we study about its structure, it contains both cell membrane and cell wall. Now another point in that bacteria lives in a moist or hypotonic environment in which the concentration of water inside the cell is less than the concentration of water outside the cell. This results in more movement of water from outside to inside the cell since we know that water moves from a place of higher concentration to a place of lower concentration.

Now when the water moves inside the bacterial cell, it can burst bacterial cell but thanks to the presence of cell wall which donot lets the burst caused.

So coming towards sugar solution, when bacteria are dipped in dilute sugary , the outside environment around a cell is sugary, and the concentration of water in the solution is less than inside the cell and water tends to leave the cell. the major effect of sugary solution is that it withdraws water from inside the body of micro organisms if the external concentration of sugar is high enough. When the water will move out of their body, they will die and their spores will not be able to germinate too.

This will eventually make our food (vegetable, fruit or any other) clean.

Hope it helps!
