6 x 6 for Sixth Grade: Ecosystems
Vocabulary
1. Energy: usually derived from sunlight, but rarely and in
small quantities derived from other sources, this energy then moves through the
ecosystem
2. Abiotic factors: including water, soil minerals, and
atmospheric gases the abiotic environment is made up of many objects and forces
that influence one another
3. biotic factors: including producer organisms, consumer organisms,
and reducer organisms; an organism’s survival and well being depend largely on getting the
food it requires on associates with other living things
4. Producer organisms: usually green plants are capable of
capturing sunlight energy through the process of photosynthesis
5. consumer organisms: include some plants and all animals
in the community
6. reducer organisms: are mainly bacteria and fungi that
decay and decompose the bodies of dead plants and animals
Sentences
1. Energy moves through the eco system going along pathways
known as food chains.
2. Abiotic factors influence the surrounding community of living
things.
3. Biotic Factors are the producer, consumer, and reducer
organisms working together to create an ecosystem.
4. Producer organisms utilize the energy to construct the
organic chemical compounds that form the plant body.
5. Consumers do not obtain their energy directly, but
acquire it secondhand from the sunlight energy originally stored in green
plants.
6. Reducer organisms feed on the complex chemical compounds
of the dead organisms and in turn release simple compounds.
Details/ Facts
1. Energy follows a one-way path through the ecosystem, with
the initial supply rapidly decreasing as it passes from one organism to the
next
2. In order for the system to function, energy must be
supplied continually at the green plant end of the chain
3. Photosynthesis is the mechanism by which green plants use
solar energy
4. A food chain is linear, where as a food web involves
intertwined food dependencies
5. Food chains are difficult to isolate in natural
ecosystems because they are usually intertwined into complex food webs
6. The energy pyramid contains of green plants, herbivores,
and primary carnivores
Questions
1. What is Photosynthesis? A: Photosynthesis is the mechanism
by which green plants use solar energy
2. What is Oxygen Restoration? A: During photosynthesis two
chemical compounds carbon dioxide and water are combined into simple sugars
3. What are the 3 levels to the Energy Pyramid? A: energy
stored by green plants, energy available to herbivores, and energy available to
primary carnivores
4. What is the main difference between a Food Chain and a
Food Web? A: A food chain is linear, where as a food web involves intertwined
food dependencies
5. When learning about Ecological Pyramids, what information
does a numbers pyramid teach? A: It teaches that there are so many levels and
whoever is at the top of the pyramid is at the top of the ecosystem
6. When learning about Ecological Pyramids, what information
does a biomass pyramid teach? A: A biomass pyramid teaches the importance of
learning about the food the animal or plant eats
Math *Column Method Division lesson & worksheet
Also learned new Math vocabulary words:
Array
Inverse
Quotient
1. 137 / 9 = 15 R 2
2. 1894 / 8 = 236 R 6
3. 8713 / 4 = 2178 R 1
4. 2049 / 13 = 157 R 8
5. 47820/ 9 = 5313 R 3
6. 3896 / 11 = 354 R 2
Current Events
Ecosystem Observation Worksheet Back Pond
Date: 10/06/11 Season:
Fall
Time of observation: 1:30 Duration
of observation: 20 mins
1. List
three details or parts of the ecosystem you are observing:
Dart (frog): hiding behind rock, weather is
too cold for him
Pirate (fish): deep in the water, not near
the waterfall, interacting with other fish
Tiger rock: whiter, leaves covering it, a
little bit of algae
2. What
did you notice or observe?
I observed the ecosystems between the animals
and their surroundings. I think it’s interesting to learn about the ponds and
their ecosystems because the habitat’s are so different, even though they are
the same.
3. What
elements (weather, temperature, light, etc.) affected the ecosystem during your
observation?
Cool weather, no sun on pond but sun is out,
slight wind, COLD water, lots of leaves in the water
4. What
things changed since the last time you observed the ecosystem?
There are a lot more leaves in the water, the fish are
deeper, and the water is colder
5. What
changes do you expect to happen to the ecosystem before your next observation?
Slight ice on top, no fish, covered in
leaves, no waterfall
6. On
back, draw part of the ecosystem (can be specific detail, food web,
metamorphosis chart, picture):
