#3 Ecosystems
What is an ecosystem?

What do ecosystems include?

What happens if one part of an ecosystem in damaged or destroyed?

#5: Food Chains
What do all living things need? Why?

Where do animals get it? Plants?

What do the links (arrows) in a food chain represent?

Explain how the last food chain represents a full circle of life.

Click on the tabs on the left and fill in the blanks (herbivore, omnivore, decomposer, etc)

A person is called a because they eat meat & vegetables.

Click on “Food Chain Game” in upper left hand corner
Play the game, then diagram (draw and label) the last food chain:

#6 Food Webs

Choose a food Web

Name a consumer in your food web

Name a producer in your food web

Name a decomposer(if there is one) in your food web

#7 Energy in an Ecosystem

Write three to five sentences describing what you learned:

Draw and label an Energy Pyramid:

Why are there less organisms as you move up the energy pyramid?

#8 10% Rule and Energy Pyramids

Nearly all of the ¬¬¬¬¬ that drives ecosystems ultimately comes from . , which is an factor, by the way, enters the ecosystem through the process of photosynthesis.
Why are plants called producers?

What are other producers besides plants?

How much energy to consumers obtain when they eat? What happened to the rest?

Environmental science studies the interactions between the physical, chemical, and biological components of the environment, including their effects on all types of organisms. earth science (also known as geoscience), is an inclusive term for all sciences related to earth (geology, meteorology, oceanogr maphy, etc).  although environmental and earth science cover essentially the same material, environmental science places greater emphasis on the biological realm, while earth science places greater emphasis on the physical realm.    environmental and earth science study the interactions of four major systems or “spheres” (figure 8.6).  the  geosphere  consists of the core, mantle and crust of the earth.the  atmosphere  contains all of the earth’s air and is divided into troposphere, stratosphere, mesosphere, thermosphere and ionosphere.the  hydrosphere  contains all of the solid, liquid and gaseous water on earth, extending from the depths of the sea to the upper reaches of the troposphere where water is found.  ninety-seven percent of the hydrosphere is found in salty oceans, and the remainder is found as vapor or droplets in the atmosphere and as liquid in ground water, lakes, rivers, glaciers and snowfields.  the  biosphere  is the collection of all earth’s life forms, distributed in major life zones known as biomes:   tundra, boreal forest, temperate deciduous forest, temperate grassland, desert, savannah, tropical rainforest, chaparral, freshwater, and marine.although the four systems have their unique identities, there is substantial interaction between them.  environmental scientists study the effects of events in one sphere on the other spheres. for example, a volcanic eruption in the geosphere may cause profound direct and indirect effects on the hydrosphere, atmosphere and biosphere as follows: example 1 (volcano)    on may 18, 1980, mount saint helens, in the state of washington, erupted.  this event altered the surrounding environment, and provided scientists with an opportunity to study the effects of volcanic eruptions on the geosphere, hydrosphere, atmosphere and biosphere.  such studies are vital because volcanic eruptions will continue to occur, and will have increasing impact on humans as people continue to settle lands closer to dormant volcanoes. the following are but a few of the myriad of interactions resulting from a volcanic 

The answer is one amu.
