transfer of energy

For the "INSECTS to FROGS" relationship , select the answer that describes the type of transfer that is shown by the arrow in the model?

transfer of energy and matter

For the "CATTAILS to MUSKRATS" relationship , select the answer that describes the type of transfer that is shown by the arrow in the model?

transfer of energy and matter

in the model, which of the following can be a source of food for consumers?

Both producers and consumers

Which statement would NOT support your answer for #8 using examples from the model.

A sedge is a producer and is a source of food for a deer, which is a consumer.

When carbon dioxide and water are used by a sedge to make sugar, there is a transfer from a(n) ________ to a(n) ________ part of an ecosystem.

When carbon dioxide and water are used by a sedge to make sugar, there is a transfer from a(n) abiotic to a(n) biotic part of an ecosystem.

When a sedge is eaten by a swamp sparrow , there is a transfer from a(n) _____ to a(n) ________ part of an ecosystem.

When a sedge is eaten by a swamp sparrow , there is a transfer from a(n) biotic to a(n) biotic part of an ecosystem

When a great blue heron is eaten by a bald eagle ,there is a transfer from a(n) _______ to a(n) _______ part of an ecosystem.

When a great blue heron is eaten by a bald eagle ,there is a transfer from a(n) biotic to a(n) biotic part of an ecosystem.

Consider the connections between all of the organisms throughout the food web. What process(es) is/are required to provide the sedge and cattail with the matter and energy needed for growth?

Photosynthesis & Respiration

Which correctly describes the process(es) of transforming energy from the sun into energy used by all of the other organisms throughout the food web?

photosynthesis is used to make sugar --> Producers use respiration to grow --> A consumer eats a producer --> A consumer use the matter and energy (from respiration) to grow

When the room is sealed, what is the boundary of the system being investigated?

The walls and ceiling of the special room

Use information from the graph to select your answer. During the daylight hours (6 AM to 6 PM), the overall pattern of the amount of carbon dioxide in the room is generally

decreasing

Use information from the graph to select your answer. During the dark hours (6 PM to 6 AM), the overall pattern of the amount of carbon dioxide in the room is generally _______.

increasing

During the daylight hours, I would expect the amount of oxygen to _________

increase

During the dark hours, I would expect the amount of oxygen to ___________.

decrease

During the daylight hours, carbon dioxide amounts will ___________.

decrease

During the dark hours, carbon dioxide amounts will ___________.

increase

During the dark hours, carbon dioxide amounts will ___________.

increase

(Use your knowledge of photosynthesis and respiration to describe how the evidence supports your claim.) For PART 1 include in your reasoning what is happening during the daylight.

During the day, CO2 in the room decreases. We know that photosynthesis uses CO2 and releases oxygen as a byproduct. So since CO2 is decreasing, we would expect oxygen to increase.

(Use your knowledge of photosynthesis and respiration to describe how the evidence supports your claim.) For PART 2 include in your reasoning what is happening when it is dark.

When it is dark, CO2 in the room increases. We know that photosynthesis requires light, so when it is dark, only respiration occurs. Respiration uses oxygen and releases CO2. So since CO2 is increasing, we would expect oxygen to decrease.

In addition to inputs from the air and water, what other input was required for the sugar maple to grow and how was the input used?

Nutrients get combined with glucose to make the macronutrients that form the structures that the sugar maple uses to grow.

Do algae get their matter by eating other organisms?

no

Are organisms biotic or abiotic?

biotic

Are the INPUTS for the special algae container biotic or abiotic?

abiotic

Does the algae make their own food through photosynthesis?

yes

What are the products of photosynthesis?

Glucose and Oxygen Gas

Why is light needed as an input?

Light energy is used to rearrange the atoms to make new molecules.

Plant and algae ____________________.

are similar, because they both make their own food instead of eating.
