The most famous attribute of Millennium Falcon was her hyperdrive. The hyperdrive system onboard the Falcon was fully twice the size of the hyperdrive in a standard YT-1300 freighter. This system gave her a hyperdrive class of 0.5, which was twice as fast as most Imperial warships.
A biome is a community on a global scale, and is usually defined by temperature, precipitation, and by the types of plants and animals that inhabit it. Generally, biome classification is determined by the climate and geography of an area.
An ecosystem is a community of organisms that interact with each other and with the abiotic (chemical and physical) factors in their particular environment. A biome is the largest well-defined ecosystem. Biomes include vast grasslands, continent-wide deserts, and sweeps of arctic tundra.
