Question

The diagram shots the flow of energy through an ecosystem.

The smallest amount of energy transferred between organisms and the largest amount of energy lost to the ecosystem is represented by which arrows?

	Smallest energy transfer	Largest energy loss
(a)	4	3
(b)	2	1
(c)	2	3
(d)	1	4

A. (a) B. (b) C. (c) D. (d)

Answer 1

The smallest amount of energy transferred between organisms is shown by arrow number 4. Because as we go above in a food chain the amount of energy transferred is reduced by 10%. And the largest amount of energy loss to the ecosystem is in the form of heat. It is shown by arrow number 3. This is because producers(plants) take energy from sunlight and only 1% of it is used to prepare food rest other is lost is the form of heat.
