Which of the following are correct statements about light in aquatic e...
As light wavelength decreases from red to blue light, so does the ability of light to penetrate water. Blue light penetrates best; green light is second, yellow light is third, followed by orange light and red light. Red light is quickly filtered from water as depth increases and red light effectively never reaches the deep ocean. So, red cannot be utilized by organism which is present in deeper zone of water. As we know light is a very important factor for distribution of photosynthetic aquatic organisms. And separate wavelengths of light reflect and absorb differentially in water.

Which of the following are correct statements about light in aquatic e...
I. Water selectively reflects and absorbs certain wavelengths of light:
- This statement is correct. Water has the ability to reflect and absorb different wavelengths of light. Water molecules have a strong absorption for light in the infrared region, which is why water appears to be colorless. Additionally, water absorbs light in the blue and red regions of the visible spectrum, while reflecting and transmitting light in the green region. This is why water often appears blue or green in color.
II. Photosynthetic organisms that live in deep water probably utilize red light:
- This statement is correct. Photosynthetic organisms, such as plants and algae, require light for the process of photosynthesis. In deep water, the available light decreases rapidly with depth, and the longer wavelengths, such as red light, are absorbed more quickly than shorter wavelengths, such as blue light. Therefore, photosynthetic organisms that live in deep water have adapted to utilize the available red light for photosynthesis, as it can penetrate deeper into the water and provide energy for their metabolic processes.
III. Light intensity is an important abiotic factor in limiting the distribution of photosynthetic organisms:
- This statement is correct. Light intensity plays a crucial role in the distribution of photosynthetic organisms. Different organisms have specific light intensity requirements for photosynthesis. Some organisms may require high light intensities, while others may thrive in low light conditions. The availability of light limits the distribution of photosynthetic organisms, as they need sufficient light energy for their metabolic processes. In areas where light intensity is too high or too low for a particular organism, its distribution will be limited.
In summary, all three statements are correct. Water selectively reflects and absorbs certain wavelengths of light, photosynthetic organisms in deep water utilize red light, and light intensity is an important factor in limiting the distribution of photosynthetic organisms. These factors play a crucial role in shaping the behavior and distribution of aquatic organisms in their respective environments.
