Beginning of the

● 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-

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 the future

Which part
of this food
web does

not count as

a food
chain?

Hotspot

Which organisms are apex predators?

Hotspot

Which organisms are not connected to the food chain?

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.

Trophic levels

●
I need to review and study trophic levels

●
I got this take me to virtual lab

Multiple Choice

What percent goes to the next trophic level as energy?

• 10

• 50

• 90

• 5

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.

Statement

● In terrestrial ecosystems, primary productivity is highest

in warm, wet places with plenty of sunlight, like tropical
forest regions. In contrast, deserts have the lowest
primary productivity.

● In marine ecosystems, primary productivity is highest in

shallow, nutrient rich waters, such as coral reefs and
algal beds.

Multiple Choice

What does primary productivity mean?

• Primary use of photosynthesis

• The process by which organisms make their own food from organic sources

• The process by which organisms make their own food from inorganic sources

• Primarily Mr. Allen tells us and we just believe

C(Claim)E(explain) R(reasoning)

●
Claim 10% of the energy is transferred to the next trophic level

●
Producer to consumer

●
Is it as simple as calories?

● All the biomass generated by primary producers is called gross primary

productivity. Net primary productivity is what is left over after the primary
producer has used the energy it needs for respiration. This is the portion
that is available to be consumed by the primary consumers and passed up
the food chain.

●Why are we measuring oxygen from photosynthesis?

●What else could we find?

Could you find the net for Glucose?

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.

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.
