Study Notes
Importance of Invertebrates
- Nutrient Cycling: Invertebrates play a key role in nutrient cycling through decomposition and sediment disturbance.
- Habitat Formation: Invertebrates contribute to habitat formation.
- Bioindicators: Invertebrates accumulate sensitivity to environmental changes, allowing them to monitor pollution levels and ecosystem health. They act as bioindicators.
- Wide range of bioindicators available for monitoring different ecosystems.
- Examples include bivalves, corals, and mollusks.
- Biodiversity: Invertebrates are crucial components of food webs, acting as primary consumers.
- Factors contributing to biodiversity include food web dynamics and rapid life cycles.
- Invertebrates support marine life due to refuge or food to smaller organisms.
Factors Contributing to Invertebrate Responses/Tolerances
- Behavioral Adaptations: Organisms adapt their behavior in response to environmental changes; an example is migration to avoid stress.
- Physiological Responses: Internal organ systems determine tolerance limits to environmental changes. An example is how copepods cannot survive if dissolved oxygen levels fluctuate too much.
- Feeding Habits: Diverse feeding strategies affect an organism's sensitivity to environmental changes in food availability.
Economic Importance
- Leeches: Used for medicinal purposes (antioxidant).
- Sponges, sea cucumbers, and corals: Used for cosmetic products.
- Fisheries & Aquaculture: Invertebrates like crabs, lobsters, mollusks, copepods, and polychaetes are important in aquaculture with multiple economic benefits, like food security
