- What are some biotic and abiotic factors in a mangrove habitat?
- What are the roles of and relationships among producers, consumers and decomposers in the process of energy transfer in a mangrove food web?
- What are the characteristics of populations within a mangrove forest, such as number of individuals, age structure, density and pattern of distribution?
- When conducting an experiment, what are the different variables? When using a scientific model, what are the limitations and benefits?
Objectives: By the end of this lesson, students will be able to:
- Explain and illustrate the roles of and relationships among producers, consumers and decomposers in the process of energy transfer in a mangrove food web and characterize the biotic and abiotic components in a mangrove habitat
- Explain the pathway of energy transfer through trophic levels and the reduction of available energy at successive levels
- Describe and investigate various limiting factors in a mangrove ecosystem and their impact on native populations, including food, shelter, water, space, disease, parasitism, predation and nesting sites
- Identify test variables (independent variables) and outcome variables (dependent variables) in an experiment, and the limitations and benefits of a scientific model
- Explain how hypotheses are valuable even if they turn out not to be supported by the data
