Chapter 52 Flashcards
Ecology
The scientific study of the interactions between organisms and their environment
Organismal Ecology
Includes the subdisciplinesof physiological, evolutionary, and behavioral ecology and is concerned with how an organism’s structure, physiology, and behavior meet challenges in the environment
Population
A group of individuals from the same species living in the same area
population ecology
This is the study of the factors that affect population size and why it changes over time
Community
A group of populations of different species in an area
Community Ecology
Analyzes how interactions between species such as population and competition affect community structure and organization
Ecosystem
The community of organisms in an area and the physical factors with which organisms interact
Ecosystem Ecology
Energy flow and chemical cycling between organisms and their environment
Landscape Ecology
Focuses on the factors controlling exchanges of energy, materials and organisms across multiple ecosystems
biosphere
The global ecosystem, the sum of all the planets ecosystems and ecosystems
global ecology
Examines how regional exchange of energy and materials influences the functioning and distribution of organisms across the biosphere
Ecology and Environmentalism
Ecology helps provide the scientific understanding needed to conserve and sustain life on Earth
Silent Spring
Author Rachel Carson was targetting the pesticide DDT and she used ecology to show how the pesticide was causing other populations to decline. Promoted new environmental ethics that helped ban DDT and put in place more stringent controls on other pesticides
Biogeography
The study of past and present distribution of species for the use of the evolutionary theory. Biotic and Abiotic factors affect this distribution
Predation (Biotic Factor)
This is one species eating another, and this could cause different distribution depending on how much predators and prey there are
