Describe the relationship between an action spectrum and an absorption spectrum. Explain why the action spectrum for photosynthe
Marina86 [1]

Answer:

An absorption spectrum illustrates the spectrum of light or electromagnetic radiation absorbed by the plant. This relies upon the molecular and cellular build-up of the plant. An action spectrum illustrates the spectrum of electromagnetic radiation most efficient for photosynthesis.  

The action spectrum of photosynthesis monitors the absorption spectrum of chlorophyll. The absorption spectrum suggests that how much of each wavelength chlorophyll will captivate, while the action potential can indicate to us about the wavelengths that are most operative for photosynthesis.

What are the 5 functions of nematodes in the soil
11Alexandr11 [23.1K]

Nematodes are wormlike organisms which can be seen with naked eye, live in water-filled pore spaces in the soil. Nematodes are in large number in the upper soil layers where organic matter, plant roots, and other resources are most abundant.

The functions of nematodes:

  • Free-living nematodes decompose organic material into nutrients and cycled them in the soil by feeding on some bacteria and fungi.
  • Nematodes help in distributing bacteria and fungi through the soil and along roots by carrying live and dormant microbes.
  • They used as food for higher predators, soil microorthropodes.
  • They eat disease-causing organisms, thus suppress their growth.
  • They acts as potential bio- control agents.
