Answer:
A. They eat nitrogen-containing compounds found in the soil.
Explanation:
Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.
Answer:
Organisms better adapted to the environment
Explanation:
According to the evolutionary theory proposed by Charles Darwin in "The Origin of Species" (1859), the fittest organisms are those that are better suited to the environment (i.e., have a higher fitness). These organisms have more chances to survive and reproduce, and thereby they have also more chances to leave their genes in the next generation. This process is the central concept of evolution, and it is called natural selection. In consequence, evolution produces phenotypic changes or 'adaptations' that are inherited by organisms over generations, and certain traits are lost during this process.
Answer:
You have it right its D the flow of energy
As you can see the plants have the first energy that they harnest from the sun and then the animals ate the plants along with their energy. and the dead animals were intern eaten by bacteria which is recycled by plants
Not really sure how to explain why, but the answer is C, it lacks hydrogen. I think it's because all organic compounds have carbon WITH HYDROGEN atom bonds.
