What does a climatograph tell you?

Temperature and precipitation of a biome.

100

What types of animals show Type I survivorship?

Large mammals

100

What are the three types of population distribution?

Clumped, random, uniform

100

What two factors define a biome?

Temperature and precipitation levels

100

How does the way energy flows in an ecosystem differ from how nutrients (chemicals) flow?

Energy flows one way, and nutrients recycle.

200
Give an example of a species that would have consistent mortality at all life stages.

Rodent or bird species

200

What type of survivorship curve would you see for a species that has moderate parental care?

Type II

200

What are three benefits of forming clumped distributions?

Protection from predators, working together to hunt, social needs

200

What temperatures and precipitation levels cause higher biodiversity in a biome?

Warmer temperatures and higher precipitation levels.

200

Name two carbon sources and two carbon sinks.

Carbon sources: burning fossil fuels, breathing

Carbon sinks: ocean, plants, soil

300
What are the parts of the FAST carbon cycle?

Photosynthesis (plants taking in CO2) and cellular respiration (animals breathing out CO2).

300

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.

300

What types of animals are most likely to form a uniform distribution?

Territorial animals

300

Why do rainforest biomes have higher biodiversity than desert biomes?

Rainforests have higher precipitation levels
300

What is bacteria's role in the nitrogen cycle?

Nitrogen-fixing bacteria bring nitrogen from the atmosphere into the soil. Nitrifying bacteria turn nitrogen in the soil into a form that plants can use.
400

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.

400

Would a large mammal such as a bear spend more energy producing its young or caring for its young?

A bear would spend more energy on caring for its young because it is a large mammal (Type I)
400

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)

400

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

400

How does deforestation affect the carbon cycle?

Increases CO2 in the atmosphere (because less CO2 is being absorbed by trees)

500

Name two ways to decrease the amount of CO2 in the atmosphere.

Plant more trees/plants, burn less fossil fuels

500

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.

500

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

500

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.

500

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.
