What are some problems with eating fish from higher trophic levels?

1 answer:

4 0

Trophic levels refer to where organisms fall on the food chain. Fish from higher trophic levels are often larger and have a higher dollar value at market, resulting in overfishing and the depletion of those species from the wild. If those fish are continued to be consumed at a high level, the loss of predators at the top of the food chain could throw off the balance in the ecosystem.

Which of the layers of the Earth has the following characteristics? i. It is solid and extremely hot. ii. It is the innermost la

Stella [2.4K]

Answer:

b. inner core

Explanation:

To solve this problem let's start by listing the information given. This will help us find which option best fits the characteristics provided to find the correct answer.

characteristics of mystery layer:

i. it is solid and extremely hot

ii. it is the innermost layer of the Earth

iii. it is around 800 miles thick

Now let's go through each option to determine which best matches the characteristics.

option a

outer core

The first characteristic of the mystery layer is 'it is solid and extremely hot.' The outer core of the earth, however, is a fluid layer. Therefore, this option cannot be correct.

option b

inner core

The inner core is a solid 'ball' and is about 10,800°F. It is also the inner, or last layer, of the earth and is around 800 miles thick. Therefore, it matches all characteristics of the mystery layer so, this must be the correct answer. If you would like to be sure, I also reviewed the last two options below.

option c

crust

Because the crust is the outermost layer of the planet, it does not match the second characteristic of the mystery layer. Therefore, this cannot be the correct answer to the question.

option d

mantle

Although the mantle does match the first characteristic, it does not match the second characteristic, which requires the layer to be the innermost layer of the earth. The mantle is one of the outer layers of the earth.

Now that all options are reviewed, we have determined the best solution to the problem. The correct answer to this question is b. inner core.

Identify two ways to reduce wind erosion and how do they work? Please write in complete sentences with correct capitalization, g

enot [183]

Answer:

Two ways to reduce wind erosion are: Covering the Surface of the Soil and Making use of Shelterbelts.

Explanation:

Wind erosion is a natural activity where a soil is moved from one place to another mainly because of the wind power. If so happens that a strong blow of wind comes and takes away with it the volume of soil particles and transfers it to other place creating dust storms.

Wind erosion can be reduced by Covering the Surface of the Soil. This can be done by growing vegetation which will protect the soil by the keeping the wind off the soil surface. Another way to reduce wind erosion is by making use of Field Shelterbelts. Shelterbelts are the best way because it not only reduce the wind erosion but at the same time it also conserve the soil moisture. Shelterbelts is a planting method where fields are planted in rows of varied crops.
