Ecological Succession

Ecological Succession

"How Do Ecosystems Form?"

GOALS

You will understand the difference between primary and secondary succession.

You will complete all 3 parts to this assignment:

1. Ecology Review Questions (use your previous notes)

2. Succession Video C-Notes

3. Create your own succession cartoon

Ecology Review

Complete the following questions covering previous content.

Use your previous Ecology C-Notes to answer the questions.

Multiple Choice

The table shows some observations made by four students during a field trip to a nature area.

Which student made observations of a community of organisms?

• Student 1

• Student 2

• Student 3

• Student 4

Multiple Choice

A science class is planning a field trip to a local farm that has a large pond. Which of the following lists the order of biological organization from smallest to largest that the students can expect to find at the pond?

• Organism, community, population, ecosystem

• Organism, population, community, ecosystem

• Population, organism, community, ecosystem

• Population, organism, ecosystem, community

Multiple Choice

A student is studying the ecology of a playa lake, which forms after a rainfall in a dry lake bed. The table lists the organisms that the student observed.

Which level of biological organization has the student described in the table?

• Biosphere

• Organelle

• Ecosystem

• Community

Multiple Choice

Saprophytes are fungi that feed on dead and decomposing organisms. They secrete enzymes that digest components of cell walls, such as cellulose and lignin.

Which statement explains why these fungi are an important part of the biogeochemical cycle?

• Saprophytes perform gas exchange that assists the cellular activities or autotrophs

• Saprophytes extract minerals from living tissue to recycle them back into the soil

• Saprophytes transport nutrients through the xylem and phloem in autotrophs

• Saprophytes return organic material to the soil for use by living organisms

Multiple Choice

A student sets up a compost bin outdoors. Inside the bin microorganisms convert the student's vegetable and paper scraps into rick fertilizer. Which of the following best describes the role that these microorganisms play in natural habitats?

• The microorganisms help balance the numbers of producers and consumers.

• The microorganisms help keep nutrients cycling through the ecosystem.

• The microorganisms turn solar energy into sugars.

• The microorganisms function as autotrophs.

KEY POINTS

Ecological Succession Definition

What's a Population

What's a Community

2 Types of Succession

- Primary Succession (starts from ROCK)

Pioneer Species

- Secondary Succession (starts from SOIL)

Examples of Disturbances

Type your C-Notes into your INB

This is a good example of a student's succession C-Notes. Your notes should look similar to these.

Draw your own Succession Cartoon

Click on the link "Succession Cartoon"

Read the instructions and create your own succession cartoon based on either primary or secondary succession.

See the next slide for

Create and ORIGINAL succession cartoon.

You can hand draw it or use the digital resources.

Put a picture of it in your INB.

Send me a screenshot when you are done.
