Question

question 15 (2 points) listen consider which wavelengths of light are best used by plants during photosynthesis. if you have a fish tank that has an excessive amount of algae, which color light should you use to limit the growth of the algae while still illuminating your tank? red blue orange green

Explanation:

Algae, like plants, use photosynthesis. Chlorophyll in algae absorbs red and blue light efficiently for photosynthesis but reflects green light. Using green light would limit algae growth as it's poorly absorbed for photosynthesis, while still illuminating the tank. Red, blue, and orange lights are absorbed well by algae, promoting growth.

Answer:

D. green
