What do you think Mr. Allen will dress up as for Halloween?

CAMERA POLICY

Teachers will send a private message then verbal warning if a student’s camera is not on.
Continued non-camera use will result in moving up the discipline ladder.

First offense: Teacher conferences with student and documents in IC.

Second offense: Teacher conferences with student, contacts LC and documents in IC.

Third offense: Teacher conferences with student, contacts LC, sends over to academic
coach for support and documents in IC.

Fourth offense: Academic coach submits discipline referral to discipline AP

Please make sure to turn your camera on at the beginning of each class.

You can set it to private (only teacher sees) or public (everyone sees).

Standard

SEV1. Obtain, evaluate, and communicate information to investigate the flow of energy and cycling of matter within an ecosystem.

b. Develop and use a model based on the Laws of Thermodynamics to predict energy transfers

throughout an ecosystem (food chains, food webs, and trophic levels).

(Clarification statement: The first and second law of thermodynamics should be used to

support the model.)

What are somethings that connect together around your house?

Vocabulary terms(supplement)

•Energy: The capacity to do work or produce change; it exists in various forms
such as thermal, electrical, chemical, and kinetic.
•Consumption: The act of using resources, such as energy, materials, or goods,
often measured in terms of quantity over time.
•Efficiency: A measure of how much useful work or energy is obtained from a
system or process compared to the total energy input; expressed as a percentage.
•Sustainability: The ability to maintain or improve the quality of life without
compromising the ability of future generations to meet their needs, often involving
the responsible use of resources.
•Dissipate to scatter or disperse energy, often in the form of heat,
making it unavailable for further use in biological processes.

Food Webs: Interconnected

Feeding Relationships in

Ecosystems

Slide 2

Types of Food Chains

●Grazing Food Chain:

●Begins with autotrophs (plants)

●Energy flows: Plants → Herbivores → Carnivores/Omnivores

●Detrital Food Chain:

●Begins with dead organic matter

●Energy flows: Dead organic matter → Decomposers (bacteria/fungi) →
Detritivores → Carnivores

Introduction to Food Webs

●Definition: A food web represents feeding relationships within a community

●Purpose: Shows the transfer of food energy from plants through herbivores to
carnivores

●Structure: Consists of multiple interconnected food chains

●Visualization: Arrows point from one species to another, showing energy flow

Importance of Food Webs

●Tool for investigating ecological interactions

●Helps understand energy flows in ecosystems

●Illustrates predator-prey relationships

●Reveals complexity of ecosystems

●Shows both strong and weak interactions among species

Example: Desert Ecosystem Food Web

●Plants → Grasshoppers → Scorpions → Kit Foxes

●Additional predators of scorpions:

●Golden Eagles

●Owls

●Roadrunners

Note: Real food webs are more complex with many interconnected species

LAnd pollution

Air pollution

Water pollution

notes or effects

example:nuclear energy

These materials are highly
toxic and contain poisonous
chemicals like plutonium
and uranium. They can
contaminate soil

uclear power plants produce almost no air
pollutants while operating. In fact, nuclear
power is considered a clean energy source
that can help reduce air pollution and
greenhouse gas emissions

The water used to cool
the plant's radioactive
core becomes
contaminated with
radionuclides.

Lake Karachay is
an example of
nuclear exposure
to local
environment

industrial

littering and waste
washed ashore from
boats, oil rigs, and
sewage release
plants.

when factories, mines, and
transportation release harmful
substances into the air.

fish, crustaceans and
other creatures
become ill, and some
die.

increased coal
plants of China

agricultural

occurs when
contamination created
as a by-product of
raising livestock and
growing food crops is
released into the
environment and the
contamination is vast.

SPrays like pesticide travel to local
ecosystems

contaminants can
impair the quality of
surface water and
groundwater.

natural habitats
have been
converted to farms
and pastures,
desertification of
tropical rainforests
of Africa

urbanization

Large quantities of
people living close
together, producing
trash and littering in a
dense area does
inevitably lead to land
pollution.

urban expansion methane release from land fills and emission growth

More wastewater is
discharged into local
streams.

Water ways of
PAris France are
unswimmable at
the Olympics .

Vocabulary terms(standard essential)

Energy Pyramid
The model that illustrates the flow of energy in an ecosystem,
showing how energy decreases as it moves from producers to
various levels of consumers.
10% rule of energy transfer
only 10% of the energy available at one trophic level in an
ecosystem is passed on to the next level
