Animal Behavior
Bird migration is an example of this type of behavior due to its strong genetic influence.
Innate
Define a population
Group of the same species in the same area
Bees get nectar while pollinating the flower. This would be an example of what type of relationship?
Mutualism
An example of a producer is
plants
This is a small area that contains a lot of different species that are often endemic while also being threatened by humans.
Biodiversity hotspot
A school of fish exhibits this form of population dispersion
clumped/grouped
Emerald ash borers came from Asia and are now killing US Ash trees. This is an example of...
invasive species
This is how much energy is passed on from one trophic level to the next
10%
Humans decrease biodiversity when they...
HIPPO+C
Altruistic behaviors are...
reduces individual fitness but increases fitness of the population as a whole
Population size changes (increases or decreases) due to these 4 things.
birth, death, emigration, immigration
This provides a community with greater stability and health
biodiversity
Where does the 90% that is not passed on go?
it excretes waste, loses heat, or used by the organism for bodily processes (does respiration)
This is an equation used to measure biodiversity
Simpson's Diversity Index
Provide an example of a behavior that increases fitness.
Foraging, Mating, Sexual Selection, imprinting
One biotic factor that can affect a population's size, and one abiotic factor that can affect a population's size are...
Biotic: Prey, food, competitors, predators, parasites, disease
Abiotic: sunlight, temperature, precipitation, soil, nutrients
Elephants eat shrubs and small trees, such as acacia, that grow on the savanna. Even if an acacia tree grows to a height of a meter or more, elephants are able to knock it over and uproot it. This feeding behavior keeps the savanna a grassland and not a forest or woodland allowing the entire ecosystem to exist. Elephants are an example of what kind of species for the grassland?
Keystone
Ecosystems have greater diversity when...
they have more nutrients, light, water, high primary production/energy
Explain how climate change impacts organisms negatively.
Teacher discretion
This can trigger a fixed action pattern
sign stimulus
Sturgeon fish produce millions of eggs that are fertilized and left in the river to hatch on their own. Only 10% survive. However, you can find some sturgeon fish that are 80 years old. Sturgeon exhibit what type of survivorship?
Type 3
After a natural disaster like a wildfire, succession of an area begins. What types of succession is this?
Secondary, because there is still soil present
Describe a way that humans have impacted the water cycle
deforestation, concrete, etc.
This is a measure of an individuals total resource usage.
Ecological Footprint
