Acid rain and other forms of pollution can cause soil acidification, which decreases the number of decomposers in the soil. What
Liono4ka [1.6K]

Answer:The question is incomplete because the options are not given. Here are the options.

a. The level of energy available in the ecosystem would increase, which would cause the population of autotrophs to increase.

b. The level of available nutrients in the soil would decrease, which would cause the population of producers to decrease

C. The population of primary consumers would increase because of increased production by autotrophs.

d. The population of primary consumers would increase because of decreased competition from decomposers.

The current answer is option B.

The level of available nutrients in the soil would decrease, which would cause the population of producers to decrease.

Explanation:

This is because when the soil is acidic it will reduce the availability of plants nutrients in the soil and it will result in accumulation of toxic chemicals which can affect the growth of plants.

If nutrients are not available for plants growth which is primary producer, it will result in poor growth, low photosynthesis and hence the production of glucose will be reduced because nutrients is essential for plants growth.

Which best describes how ocean currents are created?
Y_Kistochka [10]

Answer: Option C

Explanation:

The main reason by which the ocean currents are formed is the rotation of earth. The earth rotates on its own axis and due to this reason there is a huge mixing of the water from the equator and poles which is termed as ocean currents.

Ocean currents are important as it controls the global temperature. The water at the equator is hot and the water at poles are cold.

Due to the rotation of the earth the water and air moves from the colder regions towards the hotter region and hotter to colder and this causes ocean currents.

What causes the colored bands in the spectra we see?
storchak [24]

Answer:

Each of the different colors has its own wavelength, which reflects and refracts at its own angle, different from all the other colors. When light passes through a prism (a triangular piece of glass), it is reflected and refracted into a continuous band of colors called a spectrum.
