Grass species begin to develop flowers once the plant has developed a sufficient number of leaf blades. The size of a food chain can vary, yet there is a limit to the number of levels that a food chain can reach. The Guam rail is a flightless bird found on the island of Guam, It builds a shallow nest on the ground and lays eggs throughout the year. Rhizomes break away from the main plant easily and can stick in dirt and mud on the wheels of vehicles, enabling it to hitchhike from site to site.
