Solar energy trapped by green plants finally returns to the environment. Comment.

Green plant constitute:

Assertion: The loss of biologically useful energy as heat with every energy transfer in a food chain is a consequence of the second law of thermodynamics. Reason: Energy does not remain trapped permanetly in any organism. It is either passed on to higher trophic level or becomes available to detritivores and decomposers after the organism dies.

Which of the four most abundant element in most plants (C, H, O and N), dows a terrestrial green plant procure mainly through its roots from the soil?

The given graphs shows the productivity of an aquatic ecosystem measured in terms of dissolved oxygen produced and consumed by green plants and photosynthetic algae where PS=photosynthesis and R=respiration. What will happen during algal bloom? 1. PS will be increase, R will be decreased 2. PS will be decreased, R will be increased. 3. PS and R will not change. 4. PS+R will increase.

Photosynthesis is a process by which green plants trap_____ energy and convert it into _____ energy of carbohydrates

If 20 J of energy is trapped at producer level, then how much energy will be available to peacock as food in the following chain ? Plant - Mice - Snake - Peacock
