Decomposers are some of the most important animals on earth which help dead things decompose and rot. They vary from animals such as ants, worms and slugs to tiny animals, some so small they can't be seen. Decomposers help breakdown dead leaves, animals and plants and without them the world would be overrun with dead plants and animals. Domesticated animals are animals that humans have trained or farmed for food, clothing and pets. Domesticated animals include cows, goats, pigs, dogs, cats and rabbits.
Dominant animals tend to lead a group of animals.
For example, a group of chimpanzees is led by a dominant male, who ensures the group behaves and the protection of the groups territory. A Dorsal fin is the fin on the back of a fish or whale, porpoise or dolphin. They may be tiny on a goldifsh or may reach 2m high on an orca. Drones are male bees, usually born late in the summer to perform their one function - to mate with new queen bees. The drones then die whilst the new pregnant queens hibernate through the winter.
