represent?

🐢 Who gets eaten first

🐇 Who is the primary predator

😀 Which way the energy flows

🔊 How thermodynamics balances

Multiple Choice

What do the arrows in the food chain represent?

• Who gets eaten first

• Who is the primary predator

• The direction the energy is being transferred

• The direction the heat is going

Beginning of the
cycle

● Now that you have one sword.

Let’s give it style with the Ninja
blade to slice through anything
this cycle may bring.

● We should have time today so

be on-task to get to the work-

Sorry about the beginning it was
supposed to say Because of Class
updates and tech issues if you were not
able to observe the session use the
quizizz.

Class Norms

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).

Learning Target

I can describe the different levels of

a trophic pyramid.

I can explain the organism niche at

each level.

Back to Monday

●
Mr. Allen likes to run. 30 minutes with running in the park he is
sweaty and breathing heavy. Using thermodynamics why is he
doing this?

Poll

Why does Mr. Allen running explain thermodynamics

• The heat being wasted from burning energy

• The heat being wasted from cooking eggs

• The run was too much

• He transferred energy to the next level by being eaten by a lion

Three Truths and a Lie

🐢 A deciduous forest biome has the most
biodiversity, because of its temperate climate and
even rainfall.

🐇 Thermodynamics can be applied to environmental
science with heat and energy transfer in a food chain.

😀 Only one ecological level can be represented in a
food chain.

🔊 Glaciers melting change the chemistry of the
ocean biome.

Multiple Choice

Which of these choices is not right

• 🐇 Thermodynamics can be applied to environmental science with heat and energy transfer in a food chain.

• 🐢 A deciduous forest biome has the most biodiversity, because of its temperate climate and even rainfall

• 😀 Only one ecological level can be represented in a food chain.

• 🔊 Glaciers melting change the chemistry of the ocean biome.

Ecosystems Require Energy

Ecosystems require constant inputs of energy from sunlight or
chemicals. Producers use energy and inorganic molecules to make
food. Consumers take in food by eating producers or other living
things. Decomposers break down dead organisms and other organic
wastes and release inorganic molecules back to the environment.

Food Web

How many
different food
chains can you
find in this
desert food
web?

Poll

How many food chains did you find

• 4

• 5

• 6

• 7

Energy Movement

We have looked at ways
to show the movement of
energy in ecosystems.

Yesterday we looked at
food chains and food
webs. Today we will look
at energy pyramids and
trophic levels.

Trophic Levels

Trophic levels describe what
organisms eat. The lowest are
simple plants that get energy
from sunlight to apex predators
at the top of the food chain.

Ecosystem Energy Flow

For most of life the energy flow starts with the sun. Only 1% of
the energy entering the biome is captured. Only 10% of this
energy is passed on, the rest is converted to heat as it is used.

learning and see
the energy transfer
assignment for this

class

Progress Learning –

Energy Transfer

🔶 Log into progress learning from Clever.

🔶 Select sudy plan from the main page.

🔶 Click on the SEV 1c.

🔶 Watch the Eutrophication video and answer the questions.

🔶 Complete the task.

🔶This is a graded assignment to complete.

🔶 Do not skip ahead. We will work on the other activities later
in the week.

✅ Give a green check when you are finished!

🔶 If you finish early open the practice and choose an activity
in the Aquatic biomes section.

confetti if you
have questions
pm and see if I

can support.

Pyramid of Biomass

Look at these different ecosystems. What do you notice?

Pyramid of Numbers

How about the pyramid of numbers that looks at the number of
organisms at each level?

Ecological Pyramids

Find an

example to
use all three.
Hot question

is there
another
pyramid?

Complete this
page.

Science Fair

Look at all the things
you are interested in.

What questions can
you ask that can then
be tested by you.

Pick one and check
with your teacher.

Human Impact

Human Impact Topic

Trawling

Trawling is when fishermen pull a big
net behind or next to the boat and
catch everything in front of the net.
There is a lot that is caught that dies
and is not the fish that the fishermen
wanted. This is called bycatch.
