What do seaweed eat?

Question

If they do eat?

Answer 1

Seaweeds are a type of algae. They can make their own food from photosynthesis, but need some basics from their water as well. If you remember the photosynthesis process from school, they need water (no problem there) and carbon dioxide (from animal respiration, so fish, shrimp, crabs, clams, etc.). But they also need trace elements to thrive. These can include calcium, sulfur, phosphorous, potassium, nitrogen, iron, iodine, and others. They are able to get these elements from the water around them and rarely need to have supplements added to a tank in which they're growing.

Other than that, the only seaweed that eats is a weedy sea dragon: http://www.divegallery.com/Weedy_Sea_Dragon.htm , a relative of seahorses that eat small invertebrates.

Answer 2

Seaweed don't eat. They are plants and get their food from the sun/lighting through photosynthesis.

Answer 3

Erm, seaweed is a plant. It processes photosynthetic rays from the sun into glucose for energy.

Answer 9

we haven't got appendix that are fully functioning any more so our bodies wouldn't be able to process grass, seaweed isn't the grass of the sea, its the weed of the sea, and we can actually eat weeds and flowers, just not grass!

Answer 10

Seaweed does use photosynthesis but also absorbs nitrates and phosphates from the water as food. Seaweed is a form of algae. It's considered a macro algae while most of your common algaes in aquariums are considered micro algae. They all use the same thing for nutrients. Nitrates, phosphates, and light.
