Systems
Which of the following best describes an open system?
A. A system that exchanges both matter and energy with its surroundings.
This area is where life exists.
Biosphere
Which statement best describes an ecological niche?
a. The physical location where an organism lives
b. The role and lifestyle of an organism in its environment
c. The type of food an organism eats
d. The organism's habitat preferences
b. The role and lifestyle of an organism in its environment
What type of population dispersion is The Population is EVENLY SPACED?
Uniform
What is the maximum population size of a species that a particular environment can normally and consistently support in terms of resources?
Carrying Capacity
Which Earth System includes soil, rocks, and minerals?
Geosphere
A group of the same species that lives in the same area.
Population
What is a habitat?
*Give me a definition*
Area that includes all of the biotic and abiotic factors in the environment where an organism lives.
How can you characterizes LOGISTIC growth on a graph?
S-Shaped Growth Curve
What types of limiting factors are these:
Competition, Predation, and Parasitism/Disease
Density-dependent factors
All the inputs and outputs are contained in this system.
Isolated System
what is a biotic factor in an ecosystem?
Weather or Living Organisms?
Living Organisms
What type of symbiotic relationship benefits one organism while harming another?
Parasitism
What are the two types of population growth?
Exponential Growth and Logistic Growth
What is a resource or condition that restricts growth?
Limiting Factor
What are the five Earth systems?
Geosphere (land)
Hydrosphere (water)
Biosphere (life)
Atmosphere (air)
Anthrosphere (human impact).
Many different (__________) make up a biome.
*Fill in the blank*
Ecosystems
the process by which one organism captures and feeds on another organism.
Predation
What conditions may occur when a population is in exponential growth? Select all corrections answers.
A. Birth rate is greater than death rate
B. Birth rate is less than death rate
C. Immigration rate is greater than emigration rate
D. Immigration rate is less than emigration rate.
A. Birth rate is greater than death rate
C. Immigration rate is greater than emigration rate
What are at least 2 density-independent factors?
Weather
Natural disasters
Human Activity
What is a feedback loop?
Feedback loop is formed when an output returns to become an input in the same system that made the
output.
Put this in the correct order from smallest to largest:
Biosphere
Community
Population
Biome
Ecosystem
Individual
Individual → Population → Community → Ecosystem → Biome → Biosphere
Define the three types of symbiosis
Mutualism: Both benefit
Commensalism: One benefits, other unaffected
Parasitism: One benefits, one harmed
Describe IN DEPTH, what is logistic growth.
Population begins with slow growth, followed by a period of exponential growth, before leveling off to a stable size.
Why is fire considered a density-independent limiting factor?
