Although beavers are social creatures in the sense that they tend to mate for life and live with their families, they are also very territorial. in fact, in order to prevent other beavers from intruding, they create scent mounds around the perimeter of their territories. because of this behavior pattern, a. the number of beaver populations that an ecosystem can support is limited by the amount of space available to make habitats. b. there can be an unlimited number of beavers living in an ecosystem, as long as intruders can become part of a family. c. intruders are forced to adapt and create nests in trees, like birds, rather than live on the water. d. food and other resources are often shared between different families living in an ecosystem.
