The answer is pollution, because solar energy is costly, difficult to maintain, and fairly complex.
The first animal fossils would be most like the main body bones. I hope that helped
The statement “Decomposers are those organisms that recycle matter in the ecosystem” describes decomposers. Decomposers are organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition.
Answer:
it tells us that it is the change in the characteristics of a species over several generations and relies on the process of natural selection
Explanation:
Natural Selection: The process where organisms have better adapted to their environment and tend to survive and produce more offspring than those without the adaptations
With that dictionary definition we know that we develop certain characteristics in order for survival. The characteristics are developed over multiple generations. One example is that we have a part of our body that we needed before, but no longer need as we don't need to be immune to poisonous foods (or that's what our body tells us)
Energy flows from the first tropic level(the producers) to the consumers to decomposers then the cycle begins
