Abiotic
Non-living factors or components in an ecosystem or environment.
Anaerobic
A process or organism that can function without the presence of oxygen.
Aerobic
A process or organism that requires oxygen to survive or function.
Autotroph
An organism that can produce its own food using energy from sunlight or inorganic substances.
Biomass
The mass/number of biological organisms in an area or ecosystem at a given time.
Biotic
Living organisms or factors that are derived from living organisms.
Captive Breeding
The practice of breeding and raising animals in controlled environments, such as zoos or conservation centers, with the aim of increasing their population size or preserving endangered species.
Capture-Mark-Release-Capture
A technique used in population ecology to estimate the size of a population.
Carbohydrates
Serves as a primary source of energy for living organisms. They play crucial roles in cellular processes, including energy storage, structural support, and cell recognition.
Carrying Capacity
The maximum population size that an environment can sustainably support over a long period of time, given the available resources.
Chemical Energy
It is a form of potential energy that can be released during chemical reactions, such as cellular respiration, to perform various biological processes.
Chi-Squared
Tests how well the pattern of observed frequency fits an expected pattern of frequency.
Community
All populations found in one area.
Competition
Two species that use the same limited resource and have a negative impact of each other.
Consumer
An organism that has to eat to survive. They eat living or recently dead matter.
Density-Dependent
Limiting factors that have a greater effect on population growth at higher population densities.
e.g. food, nest, mates, pathogens, predators, parasites
Detritivore
An organism that feeds on dead organic matter, such as decaying plant and animal material. Uses internal digestion.
Diversity limited to island size
Diversity on islands is often limited by factors such as limited resources, isolation, and colonization abilities of species. This can result in fewer species and lower genetic diversity compared to larger landmasses.
Ecology
The study of relationships between organisms and their relationship with the environment.
Ecosystem
A community of living organisms interacting with each other and their physical environment.
Edge Effects
The changes in species composition, population dynamics, and ecological processes that occur at the boundaries or edges between different habitats or ecosystems.
These transitional zones often exhibit unique environmental conditions:
increased light
temperature fluctuations
altered nutrient availability
Emigration
The movement of individuals out of a population or habitat.
Endangered
A species that is in danger of going extinct.
Endemic
Species that are only found in one area of the world. Their habitat is limited and restricted.

Representation of the energy levels found in the trophic levels of an ecosystem.
