Low-altitude pikas survive by eating moss, but very few other animals can do so because moss is a very poor-quality food, says National Geographic. Fairfax County Public Schools reports that a few small mites and crustaceans eat moss, but most small animals use it as shelter material rather than food.Know More
Fairfax County Public Schools reports that moss is very important in the ecosystem, although not as a food source. According to National Geographic, moss is a poor-quality food because it is 80 percent indigestible fiber and does not provide sufficient nutrients. Most mammals cannot survive by eating moss exclusively, although many occasionally nibble at it. Pikas use a tactic called copraphagia to extract maximal nutrition from moss: they eat their own feces and re-digest it.
Caribou and reindeer feed primarily on a plant called caribou moss during mid-winter. However, according to Blue Planet Biomes, caribou moss isn't technically a moss; it's actually a lichen. A true moss, called Arctic moss, is eaten by some migrating birds.
Fairfax County Public Schools reports that many small animals rely on moss as a shelter material, and during droughts they may access it as a source of water. Many birds line their nests with mosses.Learn More
Light is essential for photosynthesis because plants need it energy to create glucose, which they store for later use as an energy source for cells. Plants and several other photosynthetic organisms use light energy to change water, carbon dioxide and minerals into oxygen and organic compounds packed with energy.Full Answer >
Plant-like protists include different groups of organisms, such as different types of algae, diatoms, dinoflagellates and euglenoids. Protists can be either uni-cellular or multicellular. For example, in the algae group, red algae are multicellular, but certain types of green algae can be either uni-cellular or multicellular.Full Answer >
Seeds must be dispersed by plants so that offspring are not forced to compete with parent plants for resources. For gardeners and homeowners, it is important to disperse some seeds, such as grass seeds, uniformly to ensure that the resulting lawn looks even and contains no bare patches. A number of forces disperse seeds, including wind, water, animals and seed-spreading tools.Full Answer >
Plants help people in several important ways, including filtering carbon dioxide into oxygen. They also act as food for both humans and animals and provide the basis for numerous types of medication.Full Answer >
