Question

resource partitioning
exam recovery
which of these explains why resources are partitioned in ecosystems?
resources are partitioned to make sure that all species become extinct.
resources are partitioned because resources are finite, which means that they can be used up.
resources are partitioned to keep one species from dominating another species.

Explanation:

Resources in ecosystems are finite. To avoid over - exploitation and allow co - existence of different species, they are partitioned. Partitioning helps in reducing competition and ensures the survival of multiple species. It is not to make species extinct, and while it can limit dominance, the main driver is the finiteness of resources.

Answer:

Resources are partitioned because resources are finite, which means that they can be used up.
