An object floats if it is less dense than the substance it is in. Density is found by dividing the volume of an object by its mass.
So ducks and frogs are just less dense then water. The density of water is 1g/cm^3
by exploting and trying to survive because plants make oxygen so duckweed try to take the oxygen
they need plants as food,gravel,water,elodea,and duckweed
Yes, duckweed is an autotroph because it can photosynthesize and produce its own food using sunlight, water, and nutrients from its environment.
Yes, duckweed can grow in low light conditions. While it may not grow as quickly or be as abundant compared to when it receives more light, it can still survive and propagate in low light settings. However, providing some natural or artificial light can help promote healthier growth and reproduction for duckweed.
No, duckweed does not depend on snails, nor do snails depend upon duckweed. Snails can eat a wide variety of vegetation. Duckweed does not benefit by being eaten.
Yes, duckweed is an aquatic plant.
Yes, duckweed is an aquatic plant.
Yes duckweed is the smallest flower. A dozen duckweed could fit the head of a pin.
The answer would be yes and no. Generally there are many different animals that do eat duckweed, ducks, carp, etc. However, Duckweed, (most notably native to California) is more often found in fresh water in ponds or lakes. There are also three main types of Duckweed, Lemna, Wolffia, and Spirodela. Each of course being slightly different than the other. Duckweed was often noted as being a good source of calcium, but the calcium make-up is sometimes unusable, especially by humans, mostly depending on the environment in which it is grown. Water content changes the content of the Duckweed. It is often said that it is better to eat that which eats the duckweed. So for as far as sharks go, they do not specifically eat duckweed (this includes the algae and shrimp eaters), however they would certainly benefit from it if it were injested.
Only Carps eat duckweed, such as Goldfish and Koi. Danios do not. Hope that helped. :)
Duckweed's Scientific Name is Lemna Minor
duckweed is small and can float easily
