Discuss two components that are essential to the functioning of the ecosystem.
Gre4nikov [31]

Answer:

The two components are biotic and abiotic components

Explanation:

The two components essential for the functioning of the ecosystem are:

Biotic Components:

These are the organic components like plants, pathogens, animals, human beings and other living components in the ecosystem that affects other living organisms, influences them and helps in shaping the ecosystem.

they require desired amount of nutrition and energy and energy for proper everyday functioning.

They are further classified as Producers, decomposers and consumers out of which producers prepare their own food by photosynthesis where consumers fulfills their requirement from producers and decomposers depend s on both producers and consumers for chemical breakdown into simpler and reusable forms.

Abiotic Components:

These are the inorganic components of the ecosystem like humidity, temperature, etc.

These are the non living components of the ecosystem which includes physical and chemical constituents of the environment which influences the biotic components and the ecosystem's functioning.

The abiotic components influences certain behaviors in living organisms like reproduction, growth, etc.

These components are synthesized by the process of photosynthesis by utilizing sunlight to convert these into organic compounds by primary producers which are further are the consumption of secondary producers thus increasing the organic content.

A machine does 50 J of Work on a 10 Kg Object. What is the Change in the Objects Total Energy?
Otrada [13]

The change in the total energy of the object is zero (0).

The given parameters:

work done by the machine, W = 50 J

mass of the object, m = 10 kg

To find:

the change in the total energy of the object

The change in the total energy of the object is the difference between the objects initial energy due to its position and the work done on the object.

Based on work energy-theory, the work done on the object is equal to the energy of the object.

  • The energy of the object = work-done on the object
  • The change in total energy = 50 J - 50 J = 0

Thus, the change in the total energy of the object is zero (0).

What part of the electromagnetic spectrum can be seen by humans?
Oxana [17]

Answer:

Visible light

Explanation:

Electromagnetic spectrum is the classification of the electromagnetic waves based on their frequency and wavelength. In order from the shortest to the longest wavelength, we have

Gamma rays

X-rays

Ultraviolet

Visible light

Infrared radiation

Microwaves

Radio waves

All these waves are invisible to human eye, except for the visible light part. Visible light is perceived as a different color by the human eye, depending on the wavelength of the light. In particular, we have:

Violet: 380 - 450 nm

Blue: 450 - 495 nm

Green: 495 - 570 nm

Yellow: 570 nm - 590 nm

Orange: 590 nm - 620 nm

Red: 620 nm - 750 nm
