A collection of ecosystems sharing similar climatic conditions
What is a Biome
In which biome would you find most likely find many animals with white fur?
Tundra
Which stage of succession is characterized by having a P/R ratio of t 1
What is a climax Community
Has the lowest productivity of any Biome
What are deserts?
A survey was taken to compare the diversity of insects found in a wheat field to those found in a pig pen. The wheat field had 10 different species of insects, while the pig pen held 25 different species. Which location has a greater species richness?
What is the pig pen
a biological community of interacting organisms and their physical environment
What is an Ecosystem
In which Biome would I most likely find clownfish, Sea anemones, sharks, red algae, and phytoplankton
Coral Reefs
This survival strategy involves having few children, but giving a lot of parental care to them
What is a K-Strategist
Has the largest Productivity of any Biome
What are Coral Reefs?
A survey measures rabbit population in an area. 1st capture = 30 rabbits (all were marked and released). 2 weeks later, 10 rabbits were caught (4 were marked). What is the estimated rabbit population?
75 rabbits
Ecosystem change over time after a natural or man made event damages the vegetation of an area causing it to revert back to an earlier stage of productivity
What is secondary succession
Which layer of the rain forest blocks out most of the sun?
What is the Canopy
Stages of succession characterized by low Gross Productivity due to lack of coverage, but high net productivity due to lack of competition for resources
What are early stages of succession
This wintery Biome is only more productive than Deserts and the Deep Ocean
What is Tundra
2 Habitats were analyzed to determine which was more diverse. Using Simpson's Diversity Index, calculate the Diversity of Habitat A
0.717
ecosystem change along an environmental gradient (Spacial Change)
Zonation
This Biome is characterized by having relatively stable temperatures (A Narrow Range) and high levels of precipitation
What are Tropical Rainforests?
During the process of Succession, earlier communities disappear because the
are displacement Due to Competition
An animal consumes 50kg of food in a day. 30kg of the food is used in respiration and 10kg is released as fecal waste. What is the Gross productivity of the animal?
40kg/day
2 Habitats were analyzed to determine which was more diverse. Using Simpson's Diversity Index, which Habitat is more Diverse?
Habitat A
Ecosystem change over time where a new pristine ground is colonized by new sparsely populated pioneer vegetative species
This Biome is found in latitudes between temperate and tropical forests
Deserts
What modern human activity tends to
- Lower species diversity in an area
- Reproduce early stages of Succession to maximize productivity
- Create conditions favorable for r-selected species
Modern Commercial Agricultural Practices
An animal consumes 50kg of food in a day. 30kg of the food is used in respiration and 10kg is released as fecal waste. What is the NET productivity of the animal?
10kg/day
What is the minimum number of counts necessary to calculate means and standard deviations (descriptive statistics) in a representative sample
5 measurements
