A "Natural Resource" is

Question

BlackTom AI · Accepted Answer

First, let's lay out what each option claims about a natural resource and evaluate them against the common understanding that natural resources are materials or components found in the environment that people can use.
Option a: 'materials and compounds found in the environment that people can use' This aligns well with the standard definition of natural resources, emphasizing that these materials exist in the environment and are usable by people. It captures both the environmental origin and the human utility aspect, which is central to the concept.
Option b: 'organic and nonorganic material of use to all living things' While this is close, it broadens the scope beyond human use to include all living things. Natural resources are typically discussed in the context of human use and management, so this option stretches the definition beyond the conventional focus on human needs and economic use.
Option c: 'A resource that is natural' This is tautological and rather vague. It merely restates that the resource is natural without specifying the aspect of usefulness or human use, which is essential to the practical definition of natural resources in environmental science and economics.
Option d: 'resources derived from ecosystems that are of use to humans' This option is close and often considered accurate, as natural resources are indeed derived from ecosystems and useful to humans. However, it is slightly more specific about being derived from ecosystems, which could imply a particular subset or mechanism, whereas the broader, general definition includes materials and compounds found in the environment usable by people even if they are not strictly labeled as coming from an ecosystem in every context.
In summary, option a most directly and comprehensively captures the standard, widely accepted definition: materials and compounds found in the environment that people can use. The other options either misstate the scope (b), are too vague (c), or add a subset emphasis that isn’t necessary to the core definition (d).
