Answer:

How do nutrients move through an environment? What drives the movement of nutrients?

My answer 6b: Nutrients are often transported across the environment by migrating from the physical environment into living creatures and then being recycled back into the physical environment. For example, an animal could receive nutrition by eating plants. To stay alive, the animal uses the chemical energy gained from the food. When the animal dies, the nutrients in its body return to the soil and are re-absorbed by plants. The transport of nutrients in the ecosystem is driven by nutrient cycles.

Select the correct answer. Which statement about natural selection is true? A. Natural selection and evolution are two terms for
Masja [62]

Answer:

C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.

Explanation:

Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.

Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.

Thus, the correct answer is option C.
