Answer:
B. Stored energy decreases from Consumer 2 to
Consumer 3.
Explanation:
As energy is transferred from one trophic level to another on the pyramid, the amount of stored energy available for those above a trophic level decreases.
The greatest amount of energy is found at the bottom of the pyramid, where we have the producers.
Consumers at the top of the pyramid have the least amount of stored energy.
The statement that is correct about the pyramid is: "B. Stored energy decreases from Consumer 2 to
Consumer 3."
Answer: Option D) The mountain ants could not mate with the valley ants
Explanation:
One distinguishing feature of species is their ability to mate with one another.
For example the mountain ants can mate freely with another, so also the valley ants because each belongs to the same specie.
In constrast, the valley ants cannot mate with the mountain ants due to years of reproductive isolation between them, thus resulting in both being different species ( Sympatric species, living in the same territory, but unable to interbreed)
"Viruses can't reproduce by themselves, so they are not considered living. Nor do viruses have cells: they're very small, much smaller than the cells of living things, and are basically just packages of nucleic acid and protein."
