Ecology
The study of how living organisms interact with each other and with their physical environment.
Ecologist
Person who studies different ecosystems (living and non-living).
Observation
Any description or measurement gathered by the senses or instruments
Evidence
Observations or data to support a statement, hypothesis, or point of view.
Trade-off
Potential outcome of any type of decision or action that involves some form of compromise, especially when each of the possible choices involves both advantages and disadvantages.
Introduced Species
A species that has been moved by humans from its normal habitat to a new habitat, either intentionally or by mistake.
Inference
A conclusion or the process of developing a conclusion based on evidence.
Invertebrate
An organism that does not have a jointed backbone.
Genus
A group of species that share specific characteristics and are related.
Classification
A process of grouping organisms into taxonomic levels based on shared characteristics and genetic relationships.
Vertebrate
An organism with a jointed backbone.
Species
A group of organisms with similar characteristics and evolutionary history that can successfully reproduce.
Phylum
A group of Classes of organisms that share specific characteristics.
Kingdom
Until 1990, the most general level of biological classification. Now the second level of classification, below the domain level.
Population
A group of the same species of organisms living in a specific location or habitat.
Fluctuation
A change over time in size, numbers, or other characteristics.
Scale
What you mark on the axes. It's the relation between the units you're using, and their representation on the graph i.e., the distance between marks.
Prey
An organism that is consumed by another organism.
Predator
An organism that kills another organism in order to eat it.
Energy Flow
The movement of energy through a system through producers and consumers.
Food Web
Model that shows many interconnected food chains and pathways in which energy and matter flow through an ecosystem.
Food Chain
Simplified model that shows a single path for energy to flow through an ecosystem.
Ecosystem
The interactions between organisms living in a specific area and their physical, non-living environment.
Producers
Organisms that are able to produce their own food, often through photosynthesis.
Consumer
Organism that must eat other organisms to obtain energy.
Photosynthesis
A process in which plants and algae use energy from sunlight to convert carbon dioxide and water into food.
Plankton
Small, usually microscopic, aquatic organisms that drift or weakly swim in the top layers of oceans, lakes, rivers, and ponds.
Cell Wall
A structure made of fibers of carbohydrate and protein that provides support and protection to cells of plants, fungi, and many prokaryotes.
Decomposer
An organism that obtains its energy by eating dead or decaying organisms or waste from living organisms.
Chloroplast
A pigment-containing organelle with an inner and outer membrane layer that is the site of photosynthesis within the cells of plants and some other producers.
Habitat
The specific environment where an organism lives based on what the organism requires to survive.
Biomes
A large region classified by the interaction of the living organisms, climate, and geographical features.
Community
Populations of multiple species living in the same area.
Carrying Capacity
The largest population of a species that can survive long-term based on the resources available.
Competition
Interaction between organisms or species using the same limited resources, such as food and living space.
