Study Notes
Arthur Tansley
- Introduced the concept of the ecosystem into biology.
- Ecosystems are communities of organisms and their physical environment interacting together.
Ecosystem
- Refers to a part of the world where living organisms and their physical environments interact.
- Refers to co-coordinating units that are the foundations of the Biosphere.
Ernst Haeckel
- German biologist who discovered, described and named thousands of species.
- Mapped a genealogical tree relating all life forms.
- Invented words such as phylum, phylogeny, and ecology.
Ecosystem Components
- A community of living organisms (plants, animals, and microbes) in a particular area.
- The living and physical components of an ecosystem are linked through nutrient cycles and energy flows.
- Ecosystems are often separated by boundaries that can be natural or man-made.
Ecosystem Variety
- Refers to the different types of ecosystems that exist.
- Small-scale ecosystems can include a pond, puddle, tree trunk, or under a rock.
- Medium-scale ecosystems include forests or large lakes.
- Large-scale ecosystems or collections of ecosystems with similar biotic and abiotic factors include rainforests.
Habitat
- The place where an organism lives.
- Indicates where an organism dwells.
Interactions
- Physical interactions between organisms.
Predation
- One species feeds on another.
- A lion preying on a gazelle is an example.
Competition
- Species compete for the same resources.
- A lion competing with hyenas for food is an example
Commensalism
- One species gains benefits from the interaction, but not the other.
- Remoras attaching to sharks for food and protection are an example.
Parasitism
- One species (the parasite) gains benefits at the expense of the other (the host).
- Tapeworms living inside a human are an example.
Mutualism
- Organisms of different species that gain benefits from their interactions.
- Clownfish gain protection from anemones, and anemones are given food and leftovers from clownfish.
