Ecology is a sub-discipline of _______________.
Biology
A shrimp that builds a burrow to share with fish that, in turn protects the burrow is what type of relationship?
Mutualistic
Deep ocean vents, African wildlife, and arctic glaciers are all part of the ________________.
The Biosphere
True or False:
A doctorfish grazing on ocean algae is an example of a heterotroph that is an herbivore.
True
True or False:
Iron, water, and sugar are examples of matter that are nutrients.
True
Give an example of a Biotic Factor
anything that is a living organism
A remora fish swimming beneath a shark to collect scraps while the shark remains unaffected is an example of __.
Commensalism
The algae, insect larvae, protozoans, and other living things in a large puddle would be an example of a(n) __
Biological Community
Approximately how much energy is transfered from the lower trophic level to the next trophic level?
10%
The weathering and eroding of rocks releases a substance, which is essential for the growth of many autotrophs, called __.
Phosphorus
A limiting factor is ______________
Any factor or variable that influences or limits the population of a species.
What is a close relationship that exists between two or more species?
Symbiosis
The Biosphere is the largest level of organization of Ecology. What are the other levels of Ecology?
Organism, Population, Community, Ecosystem, Biome
What do we call interconnected relationships of energy transfer?
Food webs
True or False:
Carbon and Oxygen are never connected in the Carbon Cycle.
False.
They are often connected in the Carbon Cycle.
Why do ecologists use models?
It allows them to control the variables.
The relationship between a vampire bat and it's host is called what_______________________?
Parasitism
Name three zones on Temperature Tolerance graph
Zone of Physiological Stress, Optimal Zone, Zone of Intolerance
Infer the effect on organism numbers if a disease reduced the number of primary producers to 750,000.
The number of primary, secondary, and third-level consumers would all likely decrease
Carbon trapped on the ocean floor is an example of what?
Biogeochemical Cycle
What type of Scientific study would an Ecologist take part in?
a. Classify three new rain forest insect species
b. compare fossilizes ants in amber
c. observe how coral colonizes a sunken ship
c. observe how coral colonizes an sunken ship
What is a "Niche"?
It is the role that organism has in it's environment.
Why does the Biosphere only extend 11 miles above the Earth's surface?
Because the amount of Oxygen needed for most organisms is non existent at or above that level.
What is a substance formed from decomposing matter?
Ammonia
What adverse affect could global warming have on the Water Cycle?
An increase in the air temperature could cause fewer water droplets in the atmosphere to condense into clouds. Less condensation of water vapor would result in a decrease in precipitation, which could result in damage to ecosystems, drought, and reduced crop yields. The term global warming will need to be discussed.
