Photosynthesis uses radiant energy from light converting it into . The process requires light, water, and to produce sugars. Oxygen is a byproduct. Life on earth depends on photosynthesis.

Explanation:

Photosynthesis is the process through which plants, some bacteria, and some others organisms  made their food by the use of  energy from sunlight and convert it into chemical energy to  produce sugar. The conversion of sunlight energy into usable chemical energy, is held by chlorophyll. The photosynthetic process uses water  as an electron donor and releases the oxygen.

The overall reaction of photosynthesis is:

6 molecules of water + 6 six molecules of carbon dioxide with the help of light, produce one molecule of sugar + six molecules of oxygen

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
