blue arrow 3. Create a matrix (Need help? - Matrices @ Math Dude) tablr

Use the first Row to label the columns - Species - Predator - Prey - Producer - Consumer - Decomposer -
Parasite - Host, Autotrophs - Heterotrophs.

Down the first column enter one species in each row. Examine at least 8 organisms from 5 different Classes.

blue arrow Use the matrix to sort out the relationships.

For each species :

Ask yourself - Is it a predator? If yes, place a blue checkmarkcheckmark in the cell.
If no, leave the cell blank.

Continue through each column for the species. Do all the species rows.

blue arrow Examine the matrix - What have you found?

How many of the animals are predators?

What percentage of the animals are prey?

How many of the organism are producers? What percentage are consumers?

How many are Autotrophs? What percentage are Heterotrophs?

Which relationship is the most essential to the ecosystem?

Which species is the least important to the ecological balance of a wetland?

Identify 4 food chains using wetland species.

What conclusion(s) can you come to based on these observations?


Extend your efforts:

blue arrow Draw a food web of wetlands organisms. Show the flow of energy.
(You do not have to draw pictures. Use public domain images. If you prefer, type the names and draw the arrows using the draw arrow tool.)

Paste the questions into the blank document. Answer the questions in the word processing document in a contrasting color (NOT YELLOW) or font (avoid fancy fonts like: black, Symbol, dearform fomnt or broad). Save frequently as you work. I do not like losing my work. You will not like it either. Submit your assignment via an electronic class dropbox or email attachment. Save a copy of your work on your computer.

Proof read your responses. It is funny how speling errors and typeos sneak in to the bets work. smiling icon

How living things function and interact. A. Diversity of Life

"One of the most general distinctions among organisms is between plants, which use sunlight to make their own food, and animals, which consume energy-rich foods. Animals and plants have a great variety of body plans and internal structures that contribute to their being able to make or find food and reproduce. All organisms, including the human species, are part of and depend on two main interconnected global food webs."

D. Interdependence of Life - " In all environments freshwater, marine, forest, desert, grassland, mountain, and others organisms with similar needs may compete with one another for resources, including food, space, water, air, and shelter.

Two types of organisms may interact with one another in several ways: They may be in a producer/consumer, predator/prey, or parasite/host relationship."
