These are sprouted seeds. You can eat them as it is or boil them and eat. They are very healthy.
Animals and their food
Based on food they eat, animals are grouped into three groups namely, herbivores, carnivores, omnivores and decomposers.
a) Herbivores: Animals which eat only plants are called as herbivores. These are also called as grass-eating animals. e.g. Cow, sheep, goat, deer, buffalo, camel etc.
b) Carnivores: Animals which eat only small animals are called as carnivores. These are also called as flesh-eating animals. e.g. Tiger, lion, jackals, vultures etc.
c) Omnivores: Animals which eat both plants and animals are called as omnivores. e.g. Human being, bear, crow etc.
d) Decomposers: Organisms which feed on dead plants, dead animals and rotten materials for their food are called as decomposers. Examples of decomposers include bacteria, fungi, some insects etc.
e) Scavengers: some animals which eat flesh of dead animals are called scavengers. Vultures, Raccoons, Jackals, and Hyenas are some examples scavengers.
.Nectar and Honey
Honey bees collect nectar (sweet juices) from flowers, convert it into honey and store it in their hive. Flowers and their nectar may be available only for a part of year so, bees store their nectar for their use throughout the year.
