### What are the assumptions of mark recapture method?

### What method of census taking would be best to monitor tiger sharks?

Census taking for sea horses is an impossible task. The best that you can hope for is a capture-recapture exercise.

### What is a basic method used by ecologists to study the living world?

Ecologists often use observational studies to collect data on species interactions, population dynamics, and community structures in their natural environments. This method involves direct observation of organisms in their habitats, which helps ecologists understand how different species interact with each other and their environment. Additionally, ecologists may use techniques such as field experiments or modeling to further investigate ecological patterns and processes.
