give an example of a biotic limiting factor 

competition 


disease

What is the difference between biotic and abiotic factors?
Biotic- Living or ONCE living Abiotic - non-living and never has been living
100

zone that has no light in the ocean

aphotic

lichen is an example of a 

pioneer species

list the 7 steps to the scientific method in the correct order 

1. Question/observation

2. Question/observation

3. Hypothesis 

4. Experiment

5. data 

6. results

7. Share/communicate 

200
What happens when a population nears carrying capacity?
Resources become limited
200
Identify one characteristic of all biotic factors.
Needs oxygen, reproduces, growth/development, etc.

How is life affected as you go deeper into the ocean. Give 2 ways. 

1. less photosynthesis = less plant life = less food resources 

2. decrease in life makes it difficult to find a mate 

3. loss of light = adaptions like angler fish or bioluminescence

_______ succession happens as a result of a environmental disaster

secondary

300

the variable that is changed on purpose to measure a scientific question 

Independent variable 

300

A new neighborhood was built around an existing pond. The owners of the neighborhood decided to add 30 new species to the pre-existing ecosystem. Identify 2 limiting factors that could affect the populations found in this ecosystem. Explain each.

Competition for food with new species Stress- due to lack of food and possibly space ETC.

300
Is a decaying carcass biotic or abiotic? Explain.
Biotic because it was once living.

How does biodiversity affect an ecosystem's stability 

High biodiversity = stable ecosystem 

low biodiversity = less stability 

300

gradual changes in the environment 

succession

400

A scientist is testing the effect of a new drug that should help participants with hair growth. What is a viable control group 

Group that does not take any drug 

400

A population of fish living in a pond about 30 feet deep are accustomed to 40 degrees water. A severe drought occurred over the summer and now there is only 10 feet of water. How could this limit this specific population of fish?

Due to more sunlight and warmth, the fish population would most likely die out because they would not be able to adapt to the conditions.

400

List 7 abiotic factors

Water, temperature, soil, sunlight, wind, Oxygen, Rocks,

400

if biodiversity is lost ______ will occur 

extinction

400

the most stable form of an ecosystem

climax community 

500

A scientist makes a graph that shows the depth of the ocean and amount of photosynthesis taking place. What is the dependent variable in this scenario? 

amount of photosynthesis

500

What would cause a carrying capacity to change?

If the amount of available space increased, more food resources moved into the area, regrowth/succession, etc.

500

list 3 characteristics of life 

1. response to stimuli 

2. reproduction 

3. growth and development 

4. cell function 

500

What happens to a high biodiverse community if an organism is eradicated 

Some organisms may be slightly affected, however the ecosystem should be able to stabilize itself

500

List 4 characteristics of primary succession 

1. no life to begin with

2. starts with a pioneer species 

3. is a long process

4. slow gradual changes 

5. climax community
