Two species of finches found on the same galápagos island but feeding on different food sources is an example of sympatric speciation.
<h3>What is speciation?</h3>
Speciation is the evolutionary process that leads to reproductive isolation and eventually to the emergence of new species.
Sympatric speciation refers to the emergence of reproductive barriers in individuals of the same species that inhabit the same region, whereas allopatric speciation occurs in individuals separated by geographic barriers.
In conclusion, two species of finches found on the same galápagos island but feeding on different food sources is an example of sympatric speciation.

Answer:
A. donation of excited electrons by chlorophyll a to a primary electron acceptor
Explanation:
Photosystems are structures located at the thylakoid membrane that act to harvest energy light in order to convert it into chemical energy. Each photosystem is composed of a light-harvesting complex and a core complex, which in turn is composed of a reaction center. The photosynthetic reaction centers are multi-protein complexes that use light energy to catalyze the electron transfer across the chloroplast thylakoid membrane against a thermodynamic gradient. Moreover, antenna pigments are pigments that capture the energy from photons in order to transfer energy to other pigments in the photosystem (e.g., chlorophyll B and carotenes are antenna pigments, whereas chlorophyll A is the core pigment). Light energy absorbed by antenna pigments in the photosystems is transferred to the reaction center chlorophyll A molecules, thereby exiting electrons in the reaction center. A reaction center consists of two chlorophyll A molecules, which donate electrons to the primary electron acceptor.
In hot springs the rising superheated water is cooled below the boiling point by groundwater before reaching the surface. In geysers the superheated water collects in underground pockets.
