Levels of Organization Practice
Today we are going to demonstrate that we understand the various levels of organization
within the biosphere. Below I would like you to fill in the chart by drawing a picture in
each box that demonstrates that level of organization and labeling that level.
Level 1: draw one animal that would be found in Oak Park
Level 2: draw more than one of that same animal
Level 3: draw that same animal and at least two other animals
Level 4: draw those same animals and also include the environment (living and
nonliving factors) that they would live in
- Level 5: draw a picture of the United States and shade in on the continent
where our biome would be located (shade in the entire middle of the
country)
- Level 6: draw a picture of the earth in which you can see the United States
and other continents as well

Food Chains Introduction
Energy is one of the basic requirements for all living things. Indeed, much of what we
call “living” centers around obtaining food. We use food as an energy source as well as a source
of materials with which to make and repair our bodies. Even plants need energy.
Green plants convert and store energy from the sun in the process of photosynthesis.
Organisms that can make their own food are called autotrophs. Autotrophs use the sunlight or
certain chemicals to produce their own food. Since these organisms are “producing” their own
food they are also often referred to as producers.
Animals and other organisms that do not “produce their own food” are called
heterotrophs. Since these organisms have to consume other substances for energy, they are
referred to as consumers. All heterotrophs (consumers) depend upon the autotrophs
(producers) for their energy and for the chemicals of which they are made.
An animal that eats plants is called a primary consumer or an herbivore. An animal that
eats other animals or consumers is called a secondary consumer. Since carnivores eat other
animals, they are consumers. An animal that eats both plants and animals is called an omnivore.

When an organism feeds on or eats another, a food chain is formed. An example of a
simplified food chain is illustrated below. The grass grows using the sun. The grasshopper is
eaten by the frog; the frog by the snake; and finally the snake by the falcon.
9. Describe a food chain?

Another example of a food chain is written below:
Algae (water plant)
mini shrimp
crayfish
bacteria
There are two important things to notice about the food chains. When writing a food chain,
the arrow goes from the organisms being eaten into the organism eating. The mini shrimp are
going into the belly of the crayfish (think of it that way), therefore the mini shrimp are giving
energy to the crayfish.
10. Looking at the food chain above, describe how energy is flowing?

Also, the last organism, bacteria, isn’t the largest organism. When an organism is at the end of
the food chain and dies, the materials from which its body was built are returned to the
environment by bacteria, fungi, and other organisms that are called decomposers.

The interactions of organisms in the environment are very complicated. The food chain is a
simplified version of some of the complex actions that occur in nature. For example, the grass
in the first example would be eaten by a great variety of insects, birds, and mammals. We use
food chains to make the relationships among parts of an ecosystem easier to understand. The
ecosystem is all of the organisms that live in a place, together with their nonliving (air,
temperature, soil, water, etc) environment. A more realistic representation of what actually
occurs in nature would be shown in a food web. A food web is a complex web of interactions
formed by the feeding relationships among the various organisms in an ecosystem.
13. Describe the two parts of an ecosystem.
