Life Science Reading Comprehension Passage and Questions: Population Ecology (Google Document)

Introduce your students to the fascinating study of population ecology with this engaging Life Science reading comprehension resource designed for Grades 6–8. Through an illustrated informational passage and structured comprehension activities, students will explore population size, population density, population growth, carrying capacity, and the factors that influence populations in different environments while strengthening essential reading comprehension and scientific literacy skills.

Students will learn how population ecology examines groups of organisms of the same species and how their numbers change in response to environmental conditions. They will explore the differences between exponential growth and logistic growth, discovering how abundant resources can support rapid population growth while environmental limits eventually slow it down. The passage also explains carrying capacity and examines how biotic and abiotic limiting factors, including predation, disease, competition, temperature, rainfall, and drought, can influence population size. Students will discover how habitat loss, pollution, and human activities affect wildlife populations, with real-world examples involving Yellowstone National Park, fisheries management, and human population density.

This 7-page reading comprehension resource features an illustrated informational reading passage followed by 10 multiple-choice questions (targeting main idea, key details, population size and density, growth patterns, carrying capacity, limiting factors, and real-world applications), 10 true-or-false statements, 5 short-answer comprehension questions, a vocabulary matching activity with 5 terms, and a written summary activity. A complete answer key, including sample responses, is provided to support straightforward grading and review.

The activities are designed to reinforce students' understanding of key scientific concepts while developing their ability to identify important details, interpret informational texts, apply scientific vocabulary, and summarize what they have learned.
