Ecosystem Interactions
- An ecosystem is an environment where living and non-living things interact, enabling survival and affecting each other.
- Examples include tropical rainforests, coral reefs, and mangrove swamps.
- In rainforests, living things include plants and animals; non-living things include soil, air, humidity, water, and sunlight. Rainforests have distinct layers: emergent, canopy, understory, and forest floor.
- Producers (plants) provide food for consumers (herbivores and carnivores), whose feeding relationships are represented by food chains and food webs.
Coral Reefs
- Coral reefs are habitats for marine life, serving as breeding grounds.
- Types include fringing reefs (hugging shorelines), barrier reefs (between open sea and lagoon), and coral atolls (enclosing a lagoon).
Mangrove Swamps
- Mangrove swamps are ecosystems largely composed of mangrove plants and animals like crustaceans and migratory birds. Non-living components include water, sand, mud, rocks and sunlight.
- Mangrove swamps are vital for fish breeding and marine animal survival.
Ecosystem Interactions
- Commensalism: Organisms live together without harming each other (e.g., orchids on a tree).
- Mutualism: Both organisms benefit (e.g., bees and flowers).
- Competition: Organisms compete for resources (e.g., sunlight, water, nutrients).
- Predation: One organism kills another for food.
- Parasitism: One organism (parasite) depends on another (host) for food, reproduction, with potential harm to the host.
Food Webs and Chains
- Organisms are interconnected via food chains and webs.
- Food chains begin with producers, followed by consumers, and end with decomposers.
- Food webs represent interconnected food chains.
Coral Reefs (Interaction)
- Coral and algae in coral reefs have a mutualistic relationship.
- Corals receive oxygen from algae; algae get protection from corals.
Mangrove Swamps (Interaction)
- Animals like crabs and mollusks break down plant matter, supporting the ecosystem.
- Producers are the base of a food chain, for food for consumers, important to the ecosystem.
