Ecology
In unit
eight of the third nine weeks students will study
ecology. The student will analyze the flow of matter and
energy through various cycles including the carbon,
oxygen, nitrogen and water cycles.
Students will analyze the flow of energy through the
ecosystem. Food chains, food webs and energy pyramids
will be investigated and explained. Population growth
patterns and community interactions will be described.
Students will also understand the importance of making
wise choices in the use, conservation, and recycling of
resources. Students will understand that the resource
base may be limited.
Critical Questions:
- How is energy from the sun transferred through all
organisms?
- How are nutrients and elements recycled in the
environment?
- How does the existence of one organism affect
another?
- How does man positively and negatively affect the
environment and what are the long term effects of
man's actions and inactions?
- How have humans reversed negative effects they
have had on the environment?
- What could be the result of planting a native
South American plant in flower garden in the Dallas
area?

Analyze the flow of matter
and energy through various cycles including the carbon, oxygen,
nitrogen, and water cycles. Analyze the flow of matter
and energy through different trophic levels and between
organisms and the physical environment.

T11 |
Investigate and explain
the interactions in an ecosystem including food chains, food
webs, and food pyramids.
{Bio 12E}
T10; T11 |
Interpret interactions among
organisms exhibiting predation, parasitism, commensalisms, and
mutualism.
{Bio 12B}
T10; T11 |
Compare variations,
tolerances and adaptations of plants and animals in different
biomes.
{Bio 12C, 12D} |
Identify and illustrate
that long-term survival of a species is dependent on a resource
base that may be limited. Make wise choices in the use
and conservation of resources and the disposal or recycling of
materials.
