Ecology Test Review Sheet



Ecology Test Review Sheet

1. Keys to Photosynthesis and Respiration Sheet

2. Introduction to Ecology

a. What are the 6 levels of organization? Define each of these levels and draw a picture for each. (One of these you haven’t seen yet; we will be covering it today!)

b. What is the difference between a habitat and a niche?

c. What are the 4 types of relationships between organisms? Define each of these and be able to identify which relationship applies to a scenario.

3. Carbon Cycle

a. Name the 8 key players:

b. Illustrate and describe the cycle of a carbon atom using all of the above key players

c. Be able to define all the vocab. words on the Carbon Cycle Game worksheet

4. Population Dynamics

a. Be able to define and give examples for each of the vocab. words from the Tim and Moby video worksheet

b. What does tolerance mean?

c. Describe what the tolerance graph above is showing.

d. Exponential growth is the growth of the population ________________________________________

e. Draw a graph of exponential growth below. Don’t forget all the required aspects of a graph!

[pic]

f. Logistic growth takes ____________ factors acting on population growth into account. This results in a leveling off of the population size at the _______________ ______________ of the population.

g. Draw a graph of logistic growth below. Don’t forget all the required aspects of a graph!

5. Demography

a. The following graph is called an _________ ______________ ____________.

[pic]

b. What trends in population growth do you notice about the graph above? How can you tell this from the graph? (Remember the different rates at which a population can grow!)

c. What is going on in the graph below?

6. Food Web and Food Chains

a. What is the definition of ecology?

b. Name, define, and draw the 3 types of ecological pyramids.

c. What are the 3 steps of energy flow?

d. There are two ways to categorize heterotrophs. Define the 4 categories within each of these systems of identification.

e. Be able to identify the level at which an organisms would fall on an ecological pyramid.

1. If you want practice with this, Google it! There’s lots of examples out there. We will also be doing an online trophic levels lab on Monday.

f. What does trophic mean?

g. What is the difference between a food chain and a food web? Draw one of each.

h. What is the definition of a cycle of matter? (What kind of resources are involved in these cycles?)

i. What is biomagnification? Give an example of this effect.

7. Ecology topics that will be covered after the test and will be on the next test (Start thinking about these now! It’s always a good idea to start studying early…)

a. Human impact on the environment

1. acid rain, habitat destruction, non-native species, global warming, bioaccumulation, deforestation, sustainable practices, stewardship
