For the answer to the question, where do electrons get their energy in the light reactions? The answer is multiple choice letter <span>D. From photons in solar energy.
I hope my answer helped you.Feel free to ask more questions. Have a nice day!</span>
The biological species concept is the most widely accepted species concept. It defines species in terms of interbreeding.
hope this helps. :)

Explanation:
1.
Population distribution is how the individuals of the population are spatially distributed across the habitat. For example, It could be uniform distribution where spaces between individuals are more or less equal on average or clustered form of distribution where they are many individual clustered at different points.
2.
Carrying capacity is the number of individuals of a population that a habit can sustain indefinitely because they allow for the resource to replenish. If the population exceeds the carrying capacity, it becomes unsustainable and the population will likely experience in ‘burst’ in population size. A decrease in the number of resources therefore also means a decrease in the carrying capacity.
3.
Population is related to one species while a community is to many species in a habitat. Therefore population density is the number of individuals of a species, occupying a habitat, per square area. The higher this figure the higher the population density.
4.
Density-dependent factors mean that these factors are influenced by the density of the population. In this case rate of infection of the disease is dependent on the density of the population The higher the density the higher the infectivity and vice versa.
