Grade 7 Science Module: Biotic and Abiotic Components of an Ecosystem

This Self-Learning Module (SLM) is prepared so that you, our dear learners, can continue your studies and learn while at home. Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson.

Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you.

Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher’s assistance for better understanding of the lesson. At the end of each module, you need to answer the post-test to self-check your learning. Answer keys are provided for each activity and test. We trust that you will be honest in using these.

Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task.

If you have any questions in using this SLM or any difficulty in answering the tasks in this module, do not hesitate to consult your teacher or facilitator.

Environment is a collection of living and nonliving things. Mosses growing on rocks, garden snails gliding on fences, and fish swimming in bodies of water are just few examples of how living and nonliving things interact. The living components of the environment are called organisms. The nonliving components make up the physical environment of these organisms. In this lesson, you will discover more about ecosystems, the components that make them up, and the interactions that take place among and between them.

Most Essential Learning Competency:

  • Demonstrate an understanding of organisms interacting with each other and with their environment; and the biotic and abiotic components of an ecosystem.

After going through this lesson, you are expected to:

1. define abiotic and biotic components of ecosystem;

2. identify abiotic and biotic components of ecosystem; and

3. cite the importance of abiotic and biotic components of an ecosystem.
