What type of growth occurs under ideal conditions (NO LIMITING FACTORS)?
Logistic Growth
Exponential Growth
An environmental factor such as predation, disease, and competition, that depends on the number of members in a population per unit
dispersion
density- independent factor
density- dependent factor
population growth rate
An environmental factor such as storms and extreme heat or cold that affects population regardless of their density (Population size doesn't matter).
density- dependent factor
population density
dispersion
density- independent factor
The movement of individuals away from or out of a population.
emigration
immigration
dispersion
population density
Biotic or abiotic things that control the size of a population.
Limiting factor
density- dependent factor
density- independent factot

Sweeden
United States
Mexico
None
Predict the future population growth of this country.
Negative Growth (the population will shrink)

Primary Succession
Aquatic Succession
Climax Community
Which of the following best describes primary succession?
Volcano wipes out ecosystem that gradually grows back from ash covered soil
Volcano creates a new island of rock that must break down to form an ecosystem
Forest fire burns down forest that must bounce back over time
Tornado destroys a crop that must slowly grow back over time.
If farmers use a controlled burn to prevent forest fires, what would most likely be the first plants to return?
trees
shrubs
mosses
grasses
Which would most likely result in primary succession?
old forest growing
undisturbed prairie
pollution kills mountain lake species
a Newly formed volcanic island
Primary succession occurs in areas with:

no soil
soil that has been disturbed
What is an example of a disturbance that could bring about secondary succession?
Humans cut down many trees in a small region
A volcanic eruption covers a village in lava.

Clown fish live among anemones, acting as a lure for the sea anemone's prey. The clown fish get protection and shelter from the anemone. This is an example of which type of symbiosis?
Commensalism
Mutualism
Parasitism
A bee and a flower work together to benefit each other. This is an example of a ______. The bee helps the flower by pollinating it and the flower helps the bee by providing it with nectar.

Hookworms enter the human body by burrowing into the skin of the feet. Once in the skin, they enter the bloodstream and travel to the small intestine where they attach to the walls and begin to drink the person's blood and weaken the victim.
mutualism
commensalism
parasitism
Lichens are close associations of fungi and algae. The fungi hold the water supply and the algae perform photosynthesis to manufacture carbohydrates for both organisms.
mutualism
commensalism
parasitism
In the jungles of South America lives a thorn tree call an acacia. A species of ant eats secretions of the acacia, drinks its sap, and raises its young in the hollow thorns. The ants also keep competing vines from growing near the acacia tree and they help repel any insects that would damage the acacia tree.
mutualism
commensalism
parasitism
Lactobacilli are a type of bacteria that live in our lungs and destroy many of the microorganisms that enter our respiratory system. They are highly adapted to living in our lungs and can't survive in many other habitats.
mutualism
commensalism
parasitism
