Collecting data using 5 sense (qualitative, quantitative

Hypothesis Proposed explanation

Collect information Research using internet, journals, books

Experiment Testing the hypothesis

conclusion A proposed explanation of the results

7. Fill in the following diagram with the correct level: 1-Biosphere, 6-species, 4-community, 3-Ecosystem, 5-population, 2-biome

8. Fill in the following table with the correct value

9. Which has a greater value 10,000 cm or 1 km? ___1km___________________________________

CH 3 The Biosphere 1. Label the organism in the food web as a producer, consumer, herbivore, carnivore, and omnivore.

2. Using the energy pyramid describe the energy transfer between trophic levels. If a toxic pesticide was used

explain what would happen to this food chain. 10% passes from one level to the next Biological magnification- Example DDT, toxin is usually doesn’t leave the body…At each level the toxin concentration increase and the top level consumer is the one most affected. EX: DDT caused the bird egg shell to become thin

5. Identify the following as an autotroph or a heterotroph a. Daisy _A___ d. crocodile _H___ b. Rabbit _H___ e. bread mold _H__ c. Moss __A__ f. tapeworm __H__

CH 4 Ecosystems and communities

1. What is the green house effect? What gases contribute to the greenhouse effect? NATURAL HEATING OF THE EARTH’S ATMOSPHERE, CARBON DIOXIDE, METHANE , WATER VAPOR

2. What is succession? SERIES OF CHANGES IN THE ENVIRONMENT OVER TIME 3. What is the difference between primary succession and secondary succession? Give an example of

each. PRIMARY BEGINS ON SURFACES WITHOUT SOIL LIKE ROCK OR LAVA FLOW, SECONDARY BEGINS WITH SOIL AFTER A FOREST FIRE

4. Identify if the factor is biotic or abiotic a. CO2 _A__ d. lichen _B__ b. Iron _A__ e. soil _A__ c. Grass _B___ f. water _A__

5. Identify the correct biome.

a. Common consumers are antelopes, rabbits, squirrels, and gophers. TEMPERATURE GRASSLAND b. It is covered with coniferous trees such as pine and spruce. BOREAL OR TAIGA c. It has permafrost in the ground and a very short growing season. TUNDRA d. It has a constant temperature and heavy rainfall. TROPICAL RAIN FOREST e. Its main producers are lichens, mosses, grasses, and a few small trees. SHRUBLAND

f. This area is composed largely of deciduous trees with a large canopy. TEMPERATE DECIDUOUS FOREST 6. Identify the following as mutualism, parasitism, commensalism or predation

a. A flea feeds on mouse blood. ___PARASITISM_______________ b. Remoras attach themselves to a shark’s body. They then travel with the shark and feed on the

left over food scraps from the shark’s meat. ___COMMENSALISM_____________ c. The stork uses its saw-like bill to cut up the dead animals it eats. As a result, the dead animal

carcass is accessible to some bees for food and egg laying. __COMMENSALISM_________ d. Wrasse fish feed on the parasites found on the black sea bass’s body.

__MUTUALSIM_____________ e. A cheetah stalks, kills and eats a gazelle. __PREDATION___

7. A forest fire has just destroyed part of Yellowstone National Park. Put the following plants in order of their appearance as the forest begins to re-grow: trees, grasses, moss, lichens, shrubs LICHENS, MOSS, GRASSES, SHRUBS, TREES

8. How does the open ocean differ from the intertidal zone? OPEN OCEAN IS DEEP AND HAS A VARIETY OF PRODUCERS, INTERTIDAL ZONE HAS THE MOST BIODIVERSITY

9. CH 5 Populations 1. Identify the four factors that affect population growth

a. BIRTH RATE c. IMMIGRATION b. DEATH RATE d. EMIGRATION

2. What factors allow a population to grow exponentially? Draw a graph of a population that is growing exponentially. FEW PREDATORS AND UNLIMITED RESOURCES

3. What is carrying capacity? # OF ORGANISMS AN ECOSYSTEM CAN SUPPORT Draw a logistic growth graph.

Will happen to the population size? DECREASE 6. What are some examples of density-dependent factors?
