Lesson Overview
Abiotic and Biotic Factors in an Ecosystem
An ecosystem is an area where living and nonliving things depend on each other to survive. Abiotic factors include water, minerals, sunlight, air, soil, temperature, and wind. Biotic factors include plants, animals, protists, and bacteria. The lesson shows how each group depends on the others to maintain a healthy ecosystem.
The four-page lesson pairs a reading passage with comprehension questions covering ecosystem types, abiotic and biotic factors, and the roles of producers, consumers, and decomposers. A full answer key is included.
How to Use This Lesson
1. Read the lesson passage together or have students read silently (page 1). Discuss what ecosystems students have observed near their school or home.
2. Review the definitions of abiotic and biotic factors. Have students give examples of each from the passage and from their own experience.
3. Assign the comprehension questions (pages 2–3) independently. Review answers using the key on page 4.
