I think it's 420,000 kcal, because 10% of energy is lost as you move up each trophic level. To find what you started with you would multiply by 10 instead of dividing by 10. You have to multiply by 10 twice, because of the primary consumers and producers.
Answer:
autographs
Explanation:
the arrows show the flow of energy, the energy from autographs are flown into rabbits, humans, chickens and sheep because they all fed on producers.
Some flowers bloom in the spring while others bloom in the summer. This is an example of Prezygotic reproductive isolation.
Prezygotic barriers, which prevent cross-species mating or fertilisation, often have a more significant impact on overall reproductive isolation in plants than postzygotic barriers, which select against hybrid progeny. Prezygotic barriers typically evolve through adaptive divergence in response to ecological factors such as pollinators and habitat.
In studies, it is interesting to note that blooming time divergence is highest at the habitat boundary; this pattern suggests reinforcement, where selection against inadequate hybrids has increased prezygotic isolation. These case studies of sympatric and reinforcing speciation demonstrate their viability.
