Keiko takes a video of a nearby river during each season. Which part of the video proves that the river is nonliving?(1 point)
Responses
The river requires no resources to exist.
The river requires no resources to exist.
The river grew larger when it flooded in the spring.
Part of the river changed in winter when it froze.
Parts of the river move quickly.
None of the options prove that the river is nonliving. Rivers are considered living systems because they are environments that support a variety of living organisms, and they interact with their surroundings.
The part of the video that proves that the river is nonliving is when it froze in winter.
The part of the video that proves that the river is nonliving is when it freezes in winter. To arrive at this answer, we need to understand the characteristics of living and nonliving things.
Living things require certain resources, such as water, nutrients, and energy, to survive and grow. In the case of a river, it is a nonliving entity that does not require resources to exist. Therefore, the fact that the river requires no resources to exist (option 1) is correct.
Next, let's look at the other options:
- The river grew larger when it flooded in the spring: This does not necessarily imply that the river is a living entity. It could be a natural process without the involvement of any living organism.
- Parts of the river move quickly: While movement can often be associated with living organisms, it alone does not confirm that the river is living.
The final option mentioned is:
- Part of the river changed in winter when it froze: This option provides evidence that the river is nonliving. Freezing is a physical process that occurs due to temperature changes and does not require any biological functions. This change is a result of external forces and not an inherent property of a living organism.
In summary, the part of the video that proves that the river is nonliving is when it changes in winter and freezes.
