Approximately what percent of energy is passed from one trophic level to another?
10%

What is the definition of a monomer?
What is the monomer of a protein?
1) A monomer is a building block
2) Amino Acids
100
Which macromolecule provides nitrogen?
Protein

What are the products of photosynthesis and cellular respiration?
Photosynthesis - Glucose and O2
Cellular Respiration - CO2 and H2O
200
What is the difference between food chains and food webs?
A food chain refers to the different organisms that depend on each other as a source of food. Always in a linear fashion
A food web is a combination of food chains

If the producers in the ecological pyramid have 3,680,000 kcal in energy, how much energy would the secondary consumer have?
36,800 kcal
200
What organelle is responsible for breaking down food monomers?
Mitochondria
200
What process causes food to be broken down into individual monomers?
Digestion
200
What are the reactants of photosynthesis and cellular respiration?
Photosynthesis - sunlight, CO2 and H2O
Cellular Respiration - Glucose and O2

Make a food chain using scientific terminology
Sun - producer - primary consumer - secondary consumer - tertiary consumer
300
If tertiary consumers have 489 kcal of energy, how much energy would the primary consumers have?
48,900 kcal
300
Define diffusion
Diffusion is the movement of particles from a high concentration to a low concentration.

Which of the 3 macromolecules would make up a herbivores diet?
Carbohydrates
300
Which cell organelle uses sunlight directly?
chloroplasts

What would happen to the food web if all lions went extinct?
Without the presence of apex predators or tertiary consumers, the primary consumers would overpopulate. Primary consumers would be able to eat as much as they wanted and whenever they wanted. Producers or plants would be eradicated from the ecosystem in response.
CLAIM: The food web would be completely imbalanced.

The producers are receiving 9,000,000 kcal from the Sun. The primary consumers are receiving 3,500,480 kcal from the producers. Calculate the energy transfer in percentage from one level to the next.
38.89%
400
How do we get energy from the food we ingest?
When the mitochondria breaks down food, bonds are broken to release stored energy as usable ATP molecules.

Which of the 3 macromolecules would make up a wolf's diet?
Fats/Protein

22 of the beavers belong to Hufflepuff. 48 of the beavers live in the Gryffindor house. 27 of the beavers are in the Slytherin House.
What percentage of the beavers live in Hufflepuff?
22.68%

Going off of the Lion king theme, describe a ecological disturbance that could impact the ecosystem.
Possible ecological disturbances:
-floods
-FIRES
-DROUGHTS

Describe what would happen to the pyramid if floods destroyed all of the producers.
The food web would be out of balance. First possible scenario is all of primary producers would be out of food, which could cause massive starvation. If the primary consumers died off, the apex predators would not have anything to eat. This could cause the destruction of the whole ecosystem.
On the other hand, if producers were wiped out in a specific ecosystem, the primary consumers could migrate to a new location where producers are abundant. If primary consumers were to migrate, the secondary and tertiary consumers would only have each other to consume.

Explain how macromolecules are transported to individual cells.
The molecule diffuses out of the intestine and into the bloodstream from an area of high concentration to low concentration. The blood carries the digested monomers (like glucose) to the body cells where it diffuses through the cell membrane
500
There are some herbivores that breakdown stored fats. What season would this occur in (spring or winter) and why?
Herbivores tend to breakdown more stored fat during the winter because plants are scarce during winter season.

If you were comparing 3 populations' DNA sequences to each other, how would you know if any were related?
There would be few differences in nucleotides.
