Question
The major reservoir of carbon on earth is ______.
Advertisements
Solution
The major reservoir of carbon on earth is ocean.
Explanation:
Deep trenches in the ocean, and even ocean water in general, are high in dissolved carbon and organic matter, both of which act as carbon sources. Furthermore, the ocean is the largest carbon reservoir, driven by nutrient leaching and precipitation from land.

The rate of decomposition of detritus is affected by the abiotic factors like availability of oxygen, pH of the soil substratum, temperature etc. Discuss.
Assertion (A): Decomposition process is slower if detritus is rich in lignin and cutin.
Reason (R): Decomposition is largely an oxygen requiring process.
Observe the contents 1, 2, 3 and 4 of soil samples A, B and C shown in the graph. If the temperature and soil moisture of all soil samples are identical, which soil sample (s) will show faster decomposition?
1 indicates lignin content, 2 indicates chitin, 3 indicates nitrogen content, and 4 indicates sugar content
Identify the correct statements:
- Detrivores perform fragmentation.
- The humus is further degraded by some microbes during mineralization.
- Water soluble inorganic nutrients go down into the soil and get precipitated by a process called leaching.
- The detritus food chain begins with living organisms.
- Earthworms break down detritus into smaller particles by a process called catabolism.
