Question

which of these is a way in which resource partitioning drives evolution?

• through natural selection of species in which only the fittest survive
• through making sure that a few species get all the resources
• through extinction of all species

Explanation:

🆕 New Concept Discovered: Resource Partitioning and Evolution
Sharing resources drives adaptation and specialization.

Step 1: Understand resource partitioning

Resource partitioning occurs when species competing for the same limited resources evolve specialized traits to share those resources. Instead of competing directly to the point of extinction, species adapt to use different parts of a resource, feed at different times, or hunt in different areas.

Step 2: Connect to evolutionary mechanisms

When species adjust their habits to avoid direct competition, individuals with traits that allow them to utilize the alternative resource successfully are more likely to survive and reproduce. This process is driven by natural selection, where environmental pressures select for the "fittest" individuals—those best adapted to their specific niche or partitioned resource.

Step 3: Evaluate the options

• Option 1: "through natural selection of species in which only the fittest survive"

This is correct. Resource partitioning forces species to adapt to specific niches, and natural selection favors individuals with traits best suited for those specific niches.

• Option 2: "through making sure that a few species get all the resources"

This is incorrect. Resource partitioning is about dividing resources among multiple species to minimize competition, not monopolizing them.

• Option 3: "through extinction of all species"

This is incorrect. Resource partitioning actually helps prevent extinction by allowing competing species to coexist.

Answer:

through natural selection of species in which only the fittest survive
