 - Only the front views are given to you for the four shapes to the right

- use this information, build the structures, and draw the isometric projections of these shapes

- Math Geometry test (isometric, orthographic, cost calculations) on Thursday

- homework: calculate the cost to construct these structures (ground = $1000/sq, roof = $750/sq, wall = $500/sq)

Structure A (2G, 4R, 20W. Total $15000)

Different groups/classes of living organisms

 

1)    Producers (make food for itself)

- green plants (photosynthesis)

Water + CO2 ----------- plant food (sugar)+oxygen

                        chlorophyll

 

 

2)    Consumers (eat/capture something to survive)

- herbivores (plant eaters, e.g. deers, rabbits, zebras)

 

 

- carnivores (meat eaters, e.g. lions, wolves, fish, T Rex)

- omnivores (plant and meat eaters, human, bears, turtles)

 

 

 

 

 

- scavengers (feed on dead animals, they do not hunt, e.g. coyotes, ravens, vultures, hyenas) 

 

- detrivores (feed on decomposing materials by absorbing nutrients from them) e.g. Earthworms, beetles, mushrooms

 

 

 

- decomposers (eat whatever leftover by the detrivores. E.g. bacteria, bread mold, some fungi)

 

 

 

 

 

 

 

 

- all these living organisms (producer, herbivores, carnivores, omnivores, decomposers, detrivores) are needed in nature because they interact with each other to maintain a balanced ecosystem

- cannot have too many of one group of living organisms (e.g. too many deer in a forest will lead to the destruction of most green plants)
