Because the entire species is a very large area and the specific population is a particular area, therefore it is easier to study the same organisms in a smaller area than the organisms in a very large area.

Ecologists study populations to understand how they change in size, distribution, and composition over time. This information is crucial for monitoring the health of ecosystems, predicting species' responses to environmental changes, and informing conservation and management efforts. By studying populations, ecologists can also evaluate the effects of human activities on biodiversity and ecosystem functioning.
So that they may know what animal is extinct or what specie of animal should be protected.
Ecologists study feeding patterns to understand the flow of energy and nutrients in ecosystems, to assess the impact of predators on prey populations, and to identify food sources that are critical for maintaining biodiversity and ecosystem stability. By studying feeding interactions, ecologists can also predict how changes in species abundance or behavior can affect ecosystem dynamics.
ecologists study the whole environment and the animals living in the environment. zoologists, they mainly study abt the animals.
The scientific study of human populations is called demography. Demography involves analyzing statistics related to population size, density, distribution, age structure, and other characteristics to understand trends and patterns within populations. It helps to inform decision-making in areas such as public health, economics, and social policy.

An ornithologist is a scientist who specializes in the study of birds, including their behavior, physiology, ecology, and evolution. Ornithologists often conduct research in the field to observe and analyze bird populations, as well as in laboratories to study their anatomy and genetics. Their work is crucial for understanding and conserving bird species and their habitats.
