Answer: B. Water breaks down into oxygen molecules for respiration.
Water is the required for photosynthesis, a process by which plants (terrestrial and aquatic) makes their food by utilizing water as a reactant to produce oxygen and glucose as product. The glucose act as a source of energy for conducting various metabolic processes in plants but oxygen is released in the air.

This oxygen is necessary for terrestrial and aquatic animals for respiration. Therefore, water breaks down into oxygen by the process of photosynthesis, hence water plays important role in respiration in living beings.

Answer:
The outermost shell of a terrestrial planet is referred to as "crust." The Earth's crust is separated into two types: continental crust, which is older and thicker, and oceanic crust, which is younger and denser. Plate tectonics influences the dynamic geology of the Earth's crust. The outermost shell of a terrestrial planet is referred to as "crust."
The mantle is the layer immediately beneath the sima. With a thickness of 1800 miles, it is the Earth's thickest layer. The mantle is made up of extremely hot and thick rock. Under the weight of a huge load, this layer of granite even flows like asphalt. The flow is caused by large temperature differences between the mantle's bottom and top. The movement of the Earth's plates is due to the movement of the mantle! The mantle's temperature ranges from 1600 degrees Fahrenheit near the top to about 4000 degrees Fahrenheit near the bottom!
