Answer:
Since sea urchins are picky, they are used as indicator organisms in public aquariums to determine if the system is functioning properly. This is because they are very "picky" about water quality. If the water is contaminated, the sea urchins will be the first to show signs of stress, spines laying down or falling off. Do use an aquarium filter and do clean up the day after feeding. Any metal exposed to the seawater will corrode and poison the tank. A dying sea urchin will often spawn out and rot out, causing the others in the tank to spawn and die as welll.

Explanation:
Each sentence describes a different form of energy:
- The shortest wavelength of visible light is <u>violet light</u>.
- Energy that can be felt as heat but not seen is <u>infrared radiations</u>.
- Short, invisible rays that can cause eye damage is <u>ultraviolet radiations.</u>
- Visible light with the longest wavelength is <u>red light</u>.
<h3>
Define electromagnetic spectrum?</h3>
An electromagnetic spectrum is a set of frequencies and wavelengths over which an electromagnetic wave can be spread (extends).
From smallest to longest wavelength (highest to lowest frequency), the electromagnetic spectrum consists of the following types of energy:
- Gamma rays
- X-rays
- Ultraviolet radiation
- Visible light
- Infrared radiation
- Microwaves
- Radio waves
Type of energy:
Each phrase in science describes a different form of energy:
1. Violet light has the shortest wavelength of visible light.
Visible light has a wavelength of 380 to 450 nanometers.
2. Infrared radiations are energy that can be felt as heat but cannot be seen.
Infrared radiation is a form of energy that the human body perceives as heat but that cannot be seen since it is outside the visible light range.
3. Ultraviolet radiations are short, invisible rays that might cause eye injury.
Ultraviolet light, which is mostly produced by the Sun, has the potential to harm the eyes.
4. Red light is the visible light with the longest wavelength.
Red light has a wavelength of 620 to 750 nanometers.
