how did nature provide james estes with an ideal site to test his hypothesis about orcas and otters?
○ a zoo with sea otters and orcas
○ a research facility with controlled environments
○ a remote island called clam lagoon
○ a marine biology laboratory

Explanation:

For the first question: James Estes observed that after sea otter capture was restricted, their populations unexpectedly declined, leading to his research on orca predation as a cause.
For the second question: Clam Lagoon is a remote, isolated site where orcas could not access sea otters, creating a natural control group to test the hypothesis that orcas were driving sea otter population declines in other areas.

Answer:

1. They were declining
2. A remote island called Clam Lagoon
