  • An exergonic reaction owing to the negative free energy change is a spontaneous reaction.
  • The energy that is released in the exergonic reaction is usually observed  in the form of heat and light.
  • The energy is released due to the breaking of the chemical bonds.
  • Therefore, on burning of the firewood the bonds between the glucose molecules break up which leads to the release of energy in the form of heat and light and this is thus, an example of an exergonic reaction.

How are the Hawaiian honeycreepers an example of adaptive radiation?
tatuchka [14]

Answer: In adaptive radiation, many different species evolve from a single ancestor species. Each new species evolves to exploit a different niche, such as food source. In the example above, Hawaiian honeycreepers evolved a range of bill forms in response to available food sources on the Hawaiian archipelago. The honeycreepers dispersed from one founder species, and evolved in response to natural selection based on different food sources in their isolated habitats provided by water. Seed-eating birds evolved thick, short beaks.
