When comparing two ecosystems of the same type, the ecosystem that supports a greater number of species is than the ecosystem that supports only a few.

OPTIOINS:

A) less habitable

B) more sustainable

C) less biodiverse

D) more fertile

B) more sustainable

Explanation:

An ecosystem is considered to be sustainable if is able to support more life and thrive, without external support. One of the key factors upon which the sustainability of an ecosystem depends upon is the level of biodiversity of the ecosystem. A greater or higher biodiversity would mean more species of organisms with various genes are present in an ecosystem. The more biodiversity in an ecosystem, the more sustainable that ecosystem is.

Therefore, in comparing two ecosystems of the same type, the ecosystem that supports a greater number of species is said to be more sustainable than the other which supports just a few.
