A tympanic membrane, (is also called a tympanum), is the circular patch of skin directly behind the frog’s eye that we commonly call an eardrum. It functions much like our’s does.
The tympanum sends sound waves to the middle of the war then to inner ear, which allows a frog to hear both in the air and below water.
“Grass is a monocotyledon plant, herbaceous plants with narrow leaves growing from the base. A common kind of grass is used to cover the ground in a lawn and other places. Grass normally gets water from the roots, which are located in the ground.” This is NOT my information I found it on Wikipedia hope this helps
