Biology Essentials- Communities Guided Viewing Worksheet
1: What is ecology?
eco- environment
ology- study of
It is the study of the environment
2: What is BBECPO? (Define each)
3: What is a community?
A group of a number of different types of populations with interactions between them.
4: What is species composition?
The population and type of each species in a certain area.
5: What is species diversity (biodiversity)? Where is the greatest species diversity?
It is how much the species are different from one another. The equator would have the most diversity.
6: Explain the example of symbiosis with Leaf Cutter Ants and the fungus and bacteria on the ant.
As the ants feed fungi with leaves, the fungi would produce sugars. These sugars are made for ants to eat. This is a mutualism
7: What is an exponential growth pattern? Explain.
A pattern of which the animals will grow in population
8: What are the limiting factors to growth. Explain both density dependent and density
independent factors.
The limiting factors to growth would probably be things such as limited resources or lack of space. Density dependent are limiting factors based on the size of the population. Density dependent are limiting factors related to chance.
9: What is a logistic growth pattern? Explain.
This is like the exponential growth pattern, but with the added limiting factors.
10: What is the carrying capacity? Define.
This is the highest amount of population an area could handle due to limiting factors.
11: What is an age-structure diagram (population pyramid)? How it is set-up? What does it
tell you?
This diagram is set up by age and then by gender which displays the a number of individuals of each age in each gender.
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)?
eco- environment
ology- study of

2: What is BBECPO? (Define each)
- Biosphere- Any area with life on planet earth
- Biome- An area with the same climate and environment
- Ecosystem- A community with added abiotic factors
- Community- Interactions between the populations
- Population- The count of a whole species
- Organism- One living thing

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: A drop off.
