Answer 2

Answer:

1. Palk Strait, inlet of the Bay of Bengal between southeastern India and northern Sri Lanka.

2. The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.

3. Carbon dioxide gas is used by plants to make their food.

4. Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.

5. Ecosystem means a biological community of interacting organisms and their physical environment.
