Question

which of the following is not mentioned as a way humans alter ecosystems?
development of areas
introducing species
creating national parks
polluting waterways
what can happen to species when small habitat areas remain after habitat division?
they adapt quickly to new conditions
they find it difficult to recover from disaster
they develop stronger immune systems
they require less food to survive

Explanation:

For the first question: Developing areas, introducing non-native species, and polluting waterways all actively alter and disrupt ecosystems. Creating national parks is a conservation action designed to protect ecosystems, not alter them in a destructive or modifying way as the other options do.
For the second question: When habitats are divided into small fragments, species have limited resources and space. Small populations in these fragments lack the genetic diversity and range to rebound easily after disasters like fires, floods, or disease outbreaks. The other options are not typical outcomes of habitat division.

Answer:

1. C. Creating national parks
2. B. They find it difficult to recover from disaster
