1: What is ecology?
Is the study of life on our planet.
2: What is BBECPO? (Define each)
Biosphere-Wherever life is on our planet
Biome- Areas with similar climate
Ecosystem- Adding abiotic factors
Community- Populations interacting
Population-Groups of individuals
Organism- One individual
3: What is a community?
Populations interacting
4: What is species composition?
What species are found there
5: What is species diversity (biodiversity)? Where is the greatest species diversity?
- The total diversity of species found there
- The greatest species diversity is located at the equator
6: Explain the example of symbiosis with Leaf Cutter Ants and the fungus and bacteria on the ant.
Leaf cutter ants feed leaves to the fungus, the fungus which breaks down cellulose that gives sugar for ants to eat. The bacteria lives on ants, which is a mutualistic relationship
7: What is an exponential growth pattern? Explain.
When population quickly grow
8: What are the limiting factors to growth. Explain both density dependent and density independent factors.
- Limiting factors: food, space and diseases
- Density independent factors are not related to population size and are related to chance, volcanic eruption or tsunami
9: What is a logistic growth pattern? Explain.
Shows what happens when populations reach carrying capacity
10: What is the carrying capacity? Define.
Largest number of individuals of a particular species that can survive over long periods of time in an environment
11: What is an age-structure diagram (population pyramid)? How it is set-up? What does it tell you?
Shows the number of individuals by age in each gender. One side are the male and the other females and shows individual growth
12: What is the shape of a population pyramid of a young population (exponential growth)? What is the shape of a population of a stable population (logistic growth)?
- Exponential growth = pyramid
- Logistic growth = dropping off
