Which of the following statements best describes the difference in approach to studying the environment by early naturalists compared to present-day ecologists?

#Unit 10. Ecological Principles
  1. Early  naturalists  employed  a  descriptive  approach;  present-day ecologists  generate  hypotheses, design experiments, and draw conclusions from their observations.
  2. Early naturalists manipulated the environment and observed changes in plant and animal populations, while modern ecology focuses on population dynamics.
  3. Early naturalists systematically recorded what they observed in their environment; modern ecology is only concerned with man's impact on the environment.
  4. Early naturalists were interested with man's interaction with the natural world; present-day ecologists seek to link ecology to developmental biology
