What is the first step of the scientific method?

What is observing the problem?

100

What is ecology?

What is the study of relationships between organisms and between organisms and their environment?

100

What is a population?

What is a group of organisms of the same species living in the same place?

100

What does population dispersion describe?

What is how individuals in a population are spaced throughout an area?

100

A sunflower turns toward the sunlight. The sunlight is the ________, and the sunflower turning is the ________.

What are stimulus and response?

200

What is a proposed explanation based on previous knowledge and research?

What is a hypothesis?

200

What level of ecological organization includes multiple individuals of the SAME species living together?

What is a population?

200

What type of population growth occurs when a population grows without a limit?

What is exponential growth?

200

Name the THREE patterns of population dispersion.

What are clumped, uniform, and random?

200

Which type of limiting factor affects populations regardless of their size or density?

What is a density-independent limiting factor?

300

In an experiment, what is the ONE variable that the scientist intentionally changes?

What is the independent variable?

300

Put these in order from smallest to largest:

Organism 

Community 

Population 

Ecosystem

Organism → Population → Community → Ecosystem

300

What type of population growth starts quickly and then levels off?

What is logistic growth?

300

Fish form large schools, and deer gather around a water source. What type of dispersion pattern is this?

What is clumped dispersion?

300

A population has plenty of food, water, and space. Suddenly, a hurricane destroys much of the habitat. What type of limiting factor is the hurricane?

What is a density-independent limiting factor?

400

A student tests whether different amounts of sunlight affect plant growth. The amount of sunlight is changed, and plant height is measured. What is the dependent variable?

What is plant height?

400

A field contains deer, birds, insects, plants, and squirrels. Scientists are studying all of the living organisms AND the temperature and precipitation in the field. What level are they studying?

What is an ecosystem?

400

What is the theoretical maximum population size that an environment can support?

What is carrying capacity?

400

Some birds defend their territories and maintain an equal distance from neighboring nests. What type of dispersion would you expect?

What is uniform dispersion?

400

A deer population increases from 20 to 50, but the amount of food and water stays the same. What will most likely happen to competition for resources?

Competition will increase because more individuals are using the same available resources.

A student says, "If I move my orchids to a window, then they will grow taller because they will receive more sunlight." Identify the independent variable and dependent variable.

  • Independent variable = location/sunlight exposure
  • Dependent variable = height/growth of the orchids

What are the two most specific levels of classification used in binomial nomenclature?

What are genus and species? 

500

A rabbit population is becoming very crowded. The rabbits begin competing for food and space, and disease spreads more easily. Are these density-dependent or density-independent limiting factors?

What are density-dependent limiting factors?

500

DAILY DOUBLE

A population of 30 rabbits lives in a grassland with three areas containing abundant food and water. Two of those resource areas dry up. Predict how the rabbits' dispersion could change and explain why.

Students should predict that the rabbits will become more concentrated around the remaining resource area(s), changing the distribution because resource availability has changed.
