Estuaries and intertidal zones supply essential foods for all living things. The living or biotic factors like plants, animals, and microorganisms affect the ecosystem that includes coral reefs, salt marshes, mudflats, rocky shores, and mangrove forests.

This module will help you understand better how organisms interact with one other to survive in intertidal zones and estuaries.

The module is divided into two lessons, namely:

  • Lesson 1: Interactions among living things and non-living things in estuaries
  • Lesson 2: Interactions among living things and non-living things in intertidal zones

At the end of this module, you will be able to:

  • identify the biotic and abiotic components in estuaries;
  • identify the biotic and abiotic components in intertidal zones;
  • explain how these components interact with each other for the survival of organisms in estuarine and intertidal zone ecosystems.
