Fruit trees in a forest are an important habitat for a bird species and were historically a major source of food for a rodent species. Over time, the rodent species shifted their feeding behavior from fruit trees to nut trees. As rodent behavior changed, the density of fruit trees decreased, which caused significant decreases to the bird population. What kind of effect did the change in rodents exert on bird population size?

Answers

Answer:

The bird population might have to migrate in search for food or may decline in numbers.

Explanation:

This is a concept of primary producers that is trees and secondary consumers that is mouse and bids. Due to the decline in raw material available the mouse population declines and this also affects the secondary consumers that are birds of prey like hawks, owls etc.

Magnetic fields on the sun are produced by the sun’s uneven rotation and:
A. The movement of sunspots on the sun’s surface.
B. The movement of gases in the corona.
C. Gases in the convective zone.
D. Gases in the radiation zone.

Answers

Answer:

The correct answer is - C. Gases in the convective zone.

Explanation:

The heat of the sun causes the atoms to be ionized and create a charged gas known as plasma. These gases or plasma are move in the convective zone with the uneven and rapid rotation of the sun.

This creates the electric currents due to the charge in gases which ultimately create magnetic fields. Sun's rotation causes the sun's overall magnetic field to have some degree of order and to be somewhat stable over time.

bring gentle, long-lasting rains

bring heavy storms
force existing air up into atmosphere
shown as blue triangles on map

Answers

Answer:

warm: gentle long lasting rain , half red circles, slides over the top of air masses

cool: blue triangles, force existing air into atmo., heavy storms

Explanation:

Gentle, long-lasting rain, sliding over the top of existing air mass and shown as red half circles on the map was an indicator of warm fronts whereas heavy storms, forcing existing air up into the atmosphere and shown as blue triangles on the map are indicators of cold fronts.

What are warm fronts?

A warm front occurs when warm air mass overtakes colder air mass while moving forward resulting in the production of precipitation, clouds, or thunderstorms. A light rain or drizzle is also a result of warm fronts.

A cold front occurs when a cold air mass undercuts a warm air mass while moving forward. when the warm air is lifted by colder air, it causes clouds to condense resulting in thunderstorms, or even tornadoes. Severe weather accompanied by strong winds and low temperatures was created by cold fronts.

Warm fronts bring gentle, long-lasting rains, slide over the top of the existing air mass, and are shown as red half circles on the map whereas cold fronts bring heavy storms, forcing existing air up into the atmosphere, and shown as blue triangles on the map.

Therefore, warm fronts bring gentle and long-lasting rains, whereas cold fronts bring heavy storms.

Which relates the wavelength and frequency of a wave?

The frequency is the number of wavelengths that pass a fixed point in a second.

A wavelength is the distance on a wave between one frequency and the next.

The time it takes for one wavelength to pass a fixed point is the frequency.

The speed at which a wavelength travels is the frequency of the wave.

Answers

Answer:

The correct answer is - The frequency is the number of wavelengths that pass a fixed point in a second.

Explanation:

The wavelength of a wave is the distance between one point on a wave and the nearest point or one crest to another crest of a wave.  The frequency of the wave is the number of wavelengths that pass a fixed point in a second.  A period is the amount of time one wavelength requires to pass a point.

Frequency = 1/wavelength, which means if one increases other decreases.

Thus, the correct answer is - The frequency is the number of wavelengths that pass a fixed point in a second.
