What does a climatograph tell you?
Temperature and precipitation of a biome.
What types of animals show Type I survivorship?
Large mammals
What are the three types of population distribution?
Clumped, random, uniform
What two factors define a biome?
Temperature and precipitation levels
How does the way energy flows in an ecosystem differ from how nutrients (chemicals) flow?
Energy flows one way, and nutrients recycle.
Rodent or bird species
What type of survivorship curve would you see for a species that has moderate parental care?
Type II
What are three benefits of forming clumped distributions?
Protection from predators, working together to hunt, social needs
What temperatures and precipitation levels cause higher biodiversity in a biome?
Warmer temperatures and higher precipitation levels.
Name two carbon sources and two carbon sinks.
Carbon sinks: ocean, plants, soil
Photosynthesis (plants taking in CO2) and cellular respiration (animals breathing out CO2).
What type of survivorship are most fish? Why do they show this type of survivorship?
Type III. Most offspring die before reaching adulthood because fish do not give parental care.
What types of animals are most likely to form a uniform distribution?
Territorial animals
Why do rainforest biomes have higher biodiversity than desert biomes?
What is bacteria's role in the nitrogen cycle?
What is lightning's role in the nitrogen cycle?
Lightning splits nitrogen in the atmosphere and allows it to be absorbed by bacteria in the soil.
Would a large mammal such as a bear spend more energy producing its young or caring for its young?
What type of environment would cause a uniform distribution--one with plenty of resources, or one with scarce resources?
Scarce resources (species must spread out evenly to have enough resources)
What causes biomes to have different temperatures?
Uneven solar heating. The sun rays hit the equator directly, leading to these biomes having the highest average temperatures
How does deforestation affect the carbon cycle?
Increases CO2 in the atmosphere (because less CO2 is being absorbed by trees)
Name two ways to decrease the amount of CO2 in the atmosphere.
Plant more trees/plants, burn less fossil fuels
Why do Type I species follow carrying capacity more closely than Type III species? Think about amount of births and deaths.
Type I follows carrying capacity more closely because these species have few births and few deaths, leading to a relatively stable population.
What types of species most commonly form random distributions, and why? Give an example of how this would happen.
Plants, due to random dispersion of seeds. Examples: wind blowing seeds, animals spreading seeds
Why do polar biomes have such low biodiversity compared to biomes closer to the equator?
Polar biomes receive very little direct sunlight, so their temperatures are very low.
How is an algae bloom (overgrowth) caused? What are the effects of an algae bloom in a marine ecosystem?
Nitrogen and phosphorus in fertilizers run off of the land and into marine ecosystems. This causes algae overgrowth, which removes oxygen from the water, causing massive fish death.
