3. An area that provides food and shelter. ecosystem habitat community population

The correct answer is 'habitat.' A habitat is an area that provides food, water, and shelter for organisms to live and thrive. It includes all the biotic and abiotic factors that an organism needs to survive. An ecosystem, on the other hand, is a larger system that includes multiple habitats and the interactions between different organisms within those habitats. A community refers to all the different populations of organisms that live and interact within a particular area, while a population refers to a group of individuals of the same species living in a specific area.
