• The otters can find enough water resources to survive in either habitat.

• The river habitat can support a larger population of otters because rivers are larger than streams.

• The stream habitat is better suited to the otter population because streams are smaller and more secure than rivers.

• The populations of otters in both river and stream habitats decrease throughout the year as they use all available resources.

• The populations of otters in both river and stream habitats decrease in the winter because there are fewer available resources.
