Solution
The correct option is C Statements (I) and (III) are true, but statement (II) is false
The biosphere is made up of the parts of Earth where life exists, it include many ecosystems. An ecosystem includes biological communities along with the physical environment with which they interact. For example, living (fishes, frogs) and nonliving things (soil, temperature) in a pond ecosystem.
Temperature is the most important ecologically relevant environmental factor (abiotic) which varies seasonally from cold winters to hot summers. The rotation of Earth around the Sun and the tilt of its axis cause annual variations in the intensity and duration of solar radiation and temperature on Earth, resulting in distinct seasons.
The axis of Earth is slightly tilted and it rotates around the sun and in its own place around this tilted axis. Due to this, different parts of Earth receive different angles of sunlight.
A season is a period of the year that is distinguished by special climatic conditions. The four seasons are spring, summer, fall, and winter. They follow one another regularly. Each season has its own light, temperature, and weather patterns. Therefore, statement I is true.
Temperature can reach to > 50℃ in summers in the tropical regions close to the equator. Some habitats have temperatures exceeding 100℃ like thermal springs and deep sea hydrothermal vents. From the equator to the poles the average temperature decreases progressively with sub zero levels in polar areas and high altitudes. Therefore, statement II is false and statement III is true.
