What factors affect the light intensity value in a given habitat?

Some of the factors affecting intensity are: The energetic intensity of the source (the initial volume). The distance from the source (the volume at any point along the path). Any modifying elements in the light path (air, clouds, filters, reflectors, etc.) The factors affecting the intensity of light are diffraction.

How does light intensity affect a habitat?

More light availability in those habitats may give rise to a more diverse and abundant algal community, due to increased photosynthetic opportunities. A larger concentration of algae may provide more nutrients for macroinvertebrate grazers, because higher light intensity significantly increases algal biomass.

What are the two factors that affect intensity?

Intensity results from two factors: the amplitude of the sound waves and how far they have traveled from the source of the sound. Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves.

What factors affect the light intensity?

The factors affecting the intensity of light are diffraction. Light has three properties: Wavelength, speed, and amplitude. The wavelength determines the type of light (color, etc.). Speed is determined by whether light passes through a vacuum or some material.

How does light intensity affect animals?

The Major Effects of Light on Animals are as follows: … The growth, colouration of plumage or body, migration, reproduction and diapause are affected by light in various insects, birds, fishes, reptiles and mammals. Many animals prefer to remain in dark, while others like hydroids fail to survive in absence of light.

How does light intensity affect the distribution of plants?

Light intensity influences the manufacture of plant food, stem length, leaf color and flowering. Generally speaking, plants grown in low light tend to be spindly with light green leaves. A similar plant grown in very bright light tends to be shorter, better branches, and have larger, dark green leaves.

What factors influence the intensity and color of light?

The color or hue of light depends on its wavelength, the distance between the peaks of its waves. The brightness of light is related to intensity or the amount of light an object emits or reflects. Brightness depends on light wave amplitude, the height of light waves.

What does the intensity of light depend on?

Light is an electromagnetic wave. its intensity will depend on the amplitude of the wave. The amplitude of light is measured in volts per meter in one direction perpendicular to its propagation direction.

What 4 factors affect the intensity of an earthquake?

When an earthquake strikes, the intensity of earthquake shaking determines the severity of damage. In turn, the main factors affecting earthquake shaking intensity are earthquake depth, proximity to the fault, the underlying soil, and building characteristics—particularly height.

How does light intensity affect the rate of photosynthesis?

As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis. … At a very high intensity of light, the rate of photosynthesis would drop quickly as the light starts to damage the plant.

Does light intensity affect temperature?

Light dependent reactions use light energy and so are not affected by changes in temperature.

Does light intensity impact terrestrial habitats differently than aquatic habitats?

Compared to aquatic habitats, however, variations in the intensity and spectrum of light in terrestrial habitats are quite modest. This is because water, in contrast to air, has a profound effect on the transmission of light.
