Lesson 1: Ecology and How to Do It Flashcards
A group of individuals of the same species that live within a particular area and interact with one another.
population
A group of interacting species that occur together at the same place and time.
community
A physiological, morphological, or behavioral trait with an underlying genetic basis that enhances the survival and reproduction of its bearers in their environment.
adaptation
A political and ethical movement that seeks to improve and protect the quality of the natural environment through changes to environmentally harmful human activities.
Environmental Movement
A possible answer to a question developed using previous knowledge or intuition.
hypothesis
A standard scientific approach in which an experimental group (that has the factor being tested) is compared with a control group (that lacks the factor being tested).
controlled experiment
All the organisms in a given area as well as the physical environment in which they live; can include one or more communities.
ecosystem
An area that is spatially heterogeneous in one or more features of the environment, such as the number or arrangement of different habitat types; typically includes multiple ecosystems.
landscape
An iterative and self-correcting process by which scientists learn about the natural world, consisting of four steps: (1) observe nature and ask a question about those observations; (2) develop possible answers to that question (hypotheses); (3) evaluate competing hypotheses with experiments, observations, or quantitative models; (4) use the results of those experiments, observations, or models to modify the hypotheses, pose new questions, or draw conclusions.
scientific method
The following are levels of biological organization that are within the purview of ecology EXCEPT
a. Ecosystem
b. Organ
c. Population
d. Organism
e. Community
Organ
The highest level of biological organization, consisting of all living organisms on Earth plus the environments in which they live; located between the lithosphere and the troposphere.
biosphere
The niche an organism occupies as a result of limiting factors present in its habitat.
Realized niche
The performance of each treatment of a controlled experiment, including the control, more than once.
replication
The spatial or temporal dimension at which ecological observations are collected.
scale
Which is NOT an approach to the study of Ecology?
a. Mesocosm
b. Models
c. Controlled Experiments
d. Observation
e. None of the above
None of the above
