Explanation:
f grass provides 4000j energy then it will give 10% of its energy to next trophic level.
Hence
Grass-4000j
Grasshopper-400j
Frogs-40j
Snakes-4j.energy will be provided respectively.
Answer:
The energy transferred to different trophic levels is governed by the 10 percent law.
The energy transferred to grasshopper would be 400 J ( 10 percent of 4000 ), energy transferred to frog would be 40 J ( 10 percent of 400 ) and energy transferred to snake would be 4 J ( 10 percent of 40 ).
The finger like projections in the inner lining if the small intestine are called villi. They are richly supplied with blood vessels and their function is to absorb the digested nutrients ( in small intestine ).
In the large intestine function of villi is to absorb water.
