Here is a big tree at the edge of the Kern River. It is a sycamore tree.
Sycamores and willows and alders are very common along rivers.
What kind of birds might you find here? Sometimes there are many
ducks in this river. What do you think the ducks might eat?
What kind of scientist might study ducks? Sycamore trees? The
environment that these animals and plants live in? The trees and
animals belong to the Willow Tree Community and the Sycamore Tree
Community. They are part of the Kern River Ecosystem. What is a
biotic community? What is the Kern River Ecosystem? Where can
you find out? Did you try a biology textbook, a life science textbook?
Did you look in the glossary? in the index? Why should you look
What do you see in this picture? Do you see yellow?
Where? Do you see green? Where? Do you see red?
Where is the red? Plants are often green. They often
have green leaves that capture light energy from the sun
and take Carbon Dioxide from the air? Could this be
happening here? What do you think? What do you
base your ideas on? How would you test your ideas if
you were looking at the actual plants? What do you think
the yellow things might be? The red things? Could they
be parts of flowers? What are flowers? How can you
find out? How would you test your ideas. What science
studies these things? Is it geology? Botany? Biology?
Plants with green leaves are sometimes called
"producers" because they produce foods like sugars
using the light energy and the Carbon Dioxide captured
by their leaves.
Producers make food eaten by living things called
"consumers." There is a bee visiting a flower to collect
pollen and nectar made by "producer" plants. Do you
think this bee might be a food "consumer?" Can you find
the bee? What color is it? What science studies this?
What science studies bees? What science studies food
relationships, the relationship of making food for other
living things to eat? How many kinds of plants can you
find in the picture below? What is the color of their
