Chapter 1 - Nature of Ecology Flashcards
the scientific study of the relationships between organisms and their environment
ecology
hailed as a framework for understanding the relationship of humans to their environment
ecology
the study of all those complex interrelationships referred to by Darwin as the conditions of the struggle for existence
ecology
the study of the complex web of interactions between organisms and their environment at all levels of organization—from the individual organism to the biosphere
ecology
includes the physical and chemical conditions as well as the biological or living components of an organism’s surroundings
Environment
include interactions with the physical world as well as with members of the same and other species
relationships
activism with a stated aim of protecting the natural environment, particularly from the negative impacts of human activities
Environmentalism
form of environmentalism
public education programs, advocacy, legislation, and treaties
a cornerstone of the science of ecology
Darwin’s theory of natural selection
Ultimate goal of all living organisms
to pass their genes on to successive generations
consists of two basic interacting components: the living, or biotic, and the nonliving (physical and chemical), or abiotic
Ecosystem
the various kinds of organisms that inhabit our forest
Populations
(in ecology) is a group of individuals of the same species that occupy a given area
Populations
all populations of different species living and interacting within an ecosystem
Community
an area of land (or water) composed of a patchwork of communities and ecosystems
landscape
the broad-scale regions dominated by similar types of ecosystems, such as tropical rain forests, grasslands, and deserts
Biomes
the highest level of organization of ecological systems; the thin layer surrounding the Earth that supports all of life
Biosphere
abstract, simplified representations of real systems; allow us to predict some behavior or response using a set of explicit assumptions, and as with hypotheses, these predictions should be testable through further observation or experiments
