___ is the scientific study of the interactions between organisms and the environment. These interactions determine distribution of organisms and their abundance.
Ecology reveals the richness of the ____, which is the global ecosystem, the sum of all the planet's ecosystems.
____ ecology studies how an organism's structure, physiology, and (for animals) behavior meet environmental challenges.
A ____ is a group of individuals of the same species living in an area. ____ ecology focuses on factors affecting how many individuals of a species live in an area.
A ____ is a group of populations of different species in an area. ____ ecology deals with the whole array of interacting species within one.
A(n) _____ is the community of organisms in an area and the physical factors with which they interact. ____ ecology emphasizes energy flow and chemical cycling among the various biotic and abiotic components.
A ____ is a mosaic of connected ecosystems. ____ ecology deals with arrays of ecosystems and how they are arranged in a geographic region.
___ ecology examines the influence of energy and materials on organisms across the biosphere.
Ecology has a long history as a ____ science. It is also a rigorous ____ science.
Events that occur in ecological time affect life on the scale of _____ time. example: Darwin's finches on the Galapagos Islands and wet/dry cycles.
Ecologists make a distinction between ___ and ___.
___ ____ is credited with starting the modern environmental movement with the publication of Silent Spring in 1962.
global climate change
current example of ecology and environmental issues is: ___ ___ ____.
Interactions between organisms and the environment limit the ____ of species.
biogeography, biotic, abiotic
____ is a good starting point for understanding what limits geographic distribution of species. Ecologists recognize two kinds of factors that determine distribution: ____, or living factors, and ____, or nonliving factors.
___ is the movement of individuals away from centers of high population density or from their area of origin; contributes to global distribution of organisms.
____ is influenced by dispersal; revealed in natural range expansions.
___ ____ include organisms that are intentionally or accidentally relocated from their original distribution. They can disrupt the communities or ecosystems to which they have been introduced.
____ factors that affect the distribution of organisms may include: Interactions with other species, Predation, and Competition.
____ factors affecting distribution of organisms include:
temperature, water, sunlight, wind, and rocks and soil.
Most of these factors vary in space and time.
structure, pH, composition
Many characteristics of soil limit distribution of plants and thus the animals that feed upon them: physical ____, ___, and mineral ____.
temperature, water, sunlight, wind
Four major abiotic components of climate: ____, ____, ____, and ____.
___ is the long-term prevailing weather conditions in an area.
_____: patterns on the global, regional, and local level.
____ : very fine patterns, e.g. conditions encountered by the community of organisms underneath a fallen log.
solar energy, movement
Global climate patterns are determined largely by ___ ___ and the planet's ____ in space.
__ ___ plays a major part in determining the Earth's climate patterns. More heat and light per unit of surface area reach the tropics than the high latitudes.
