In diffusion, the net movement of a substance travels down its concentration gradient
Explain using the image below.

Answers

Answer:

The diagram is a representation of the diffusion.

Explanation:

In this image, there are molecules or concentrations of a particular substance is represented by the purple circle on both sides of the box in left side concentration is higher than the right side.

So the movement of these molecules is from the left corner to the right down the concentration gradient, this type of movement of the substance is known as the diffusion which moves from high concentration to low concentration.

Diffusion is the movement of molecules from the higher concentration to lower concentration.

Diffusion is the movement of molecules from the area of higher concentration to the area of lower concentration. In the image, higher concentration of molecules are present on the left side whereas lower number of molecules are present on the right side of the image.

So here diffusion occurs by movement of molecules from higher concentration to lower concentration means from left to right side of the image until the concentration becomes equal so we can conclude diffusion is the movement of molecules from the higher concentration to lower concentration.

four students drew different illustrations to show the flow of energy in a field ecosystem. Which of the illustrations below is most accurate?

Answers

The correct answer is the second illustration

Explanation:

Energy flows from one level or organism to another as one organism takes nutrients from another. In this context, the first level is plants including oats and these take nutrients from the sun and the soil to obtain energy. On the second level are herbivores including mice that feed on plants. These can be followed by other organisms such as carnivores, for example, foxes and even top predators. Finally, the last level is decomposers these include bacteria and other organisms that can obtain nutrients from plants and animals as they die and decompose.

According to this, the correct diagram is the second one because these shows accurately how energy flow from the sun to plants oats), then to animals (mouse), and finally the energy of plants and animals flows to the decomposers.

Answers

Answer:

near the Equator

Explanation:

The part of the Earth that receives the most amount of solar radiation is always near the Equator. This is because the Earth itself revolves around the run in a tilted motion, since the Earth is round this makes the Equator always closest to the sun which means it will always get the most direct amount of Sun Radiation. This radiation causes more heat which ultimately causes a greater amount of water to be evaporated in this location.
