Biology Essentials- Communities Guided Viewing Worksheet
Name: ___________________________________________
1: What is ecology?
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 that interact and change over time.
4: What is species composition?
Counting amount and type of organisms in a large area and putting them in a pie chart.
5: What is species diversity (biodiversity)? Where is the greatest species diversity?
Species diversity is the total amount we have. The greatest species diversity are 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.
Exponential growth pattern is a graph the shows the growth rate over time. Exponential growth is when populations skyrocket.
8: What are the limiting factors to growth. Explain both density dependent and density
independent factors.
Limiting factors to growth would be lack of food, no space and disease. Density dependent is based on size of population, it limits growth. Density independent are related to chance, such as a volcanic eruption.
9: What is a logistic growth pattern? Explain.
Logistic growth pattern shows how exponential growth and when it will hit the carrying capacity, eventually when there is more than the carrying capacity, then population will decline.
10: What is the carrying capacity? Define.
Carrying capacity is the maximum number of individuals an area can support.
11: What is an age-structure diagram (population pyramid)? How it is set-up? What does it
tell you? An age-structure diagram is something that shows the number of individuals by age in each gender. It is set up by age and by gender. It tells us the individual growth in Angola.
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)?
The shape of a population pyramid of a young population is a pyramid. The shape of a population of a stable population is dropping off.
