Study Notes
Organisms and Ecosystems
- Organisms interact with each other in an ecosystem, forming various relationships.
Species and Population
- A species is a basic unit of an ecosystem, defined by its ability to interbreed and produce fertile offspring.
- A population is a group of organisms that belong to the same species.
Community and Symbiosis
- A community is a group of populations that live together in a particular place at a specific time.
- Symbiosis refers to a biotic relationship between two species that live closely together in a community.
Types of Parasites
- Ectoparasite: a parasite that lives outside the body of its host.
- Endoparasite: a parasite that lives inside the body of its host.
Types of Interactions
- Competition: an interaction between organisms of the same species.
- Parasitism: a relationship where one organism benefits while the other is harmed.
- Mutualism: a relationship where both organisms benefit from each other.
- Commensalism: a relationship where one organism benefits, and the other is neither harmed nor benefited.
Living and Non-Living Things
- Biotic: refers to living things, such as organisms and their interactions.
- Abiotic: refers to non-living things, such as environmental factors and physical components.
Ecosystems
- Aquatic ecosystems are water-based ecosystems.
- Terrestrial ecosystems are land-based ecosystems.
Filter Feeders in Coral Reefs
- Filter feeders are invertebrates that live on the bottom of coral reefs.
- They wait for food to come to them.
Mangrove Swamps
- Mangrove swamps serve as a breeding ground for fish.
- The dominant organisms in mangrove swamps are bakawan, tangal, and busain.
Rain Forests
- Rainforests are the earth's oldest ecosystem, with some being 100 million years old.
- Tropical rainforests have the highest number of organisms among other land ecosystems.
Reef Types
- Fringing reefs are found close to the shore and around islands.
- Barrier reefs are located at a far distance from an island.
- Atolls are circular reef formations located at a far distance from a sunken island.
Tropical Rainforest Layers
- The emergent layer is the highest layer of the tropical rainforest.
- The understory is the shadier area of the tropical rainforest.
