Feeding Niches
This type of organism must eat other organisms to obtain its energy.
What is a Consumer?
This is the original source of energy for nearly all organisms on the planet.
What is the Sun?
Energy pyramids are shaped like triangles because this happens to the amount of available energy at higher levels.
It decreases (or there is less energy).
This group of macromolecules includes glucose and serves as a quick source of energy.
What are Carbohydrates?
Enzymes are a specialized version of this type of macromolecule.
What are Proteins?
An organism like a cow that eats only plants is known as this.
What is a Herbivore?
This diagram serves as a representation of different types of organisms in an ecosystem and how/how much energy is transferred between them.
What is a Trophic Pyramid?
In the energy pyramid, these organisms are at the very top, as they do not have any known natural predators.
What are APEX Predators?
These macromolecules, which include fats and oils, are used for long-term energy storage.
What are Lipids?
This is the specific name for the reactant that binds to an enzyme.
These organisms, such as fungi or bacteria, break down dead organic matter and "fix" nitrogen.
What are Decomposers?
In a food web containing grass and rabbits, the grass occupies this specific level.
What is the Producer (or 1st Trophic) level?
This is the name for the form of usable chemical energy found within a cell.
What is ATP (adenosine triphosphate)?
A chain of amino acids connected by peptide bonds forms this macromolecule.
This is the specific location on an enzyme where the substrate fits.
Unlike consumers, these organisms use sunlight to generate their own food through a process called photosynthesis.
What are Producers?
If a hawk eats a snake that ate a rabbit, the hawk is acting as this type of consumer.
What is a Tertiary Consumer?
If the producers in an ecosystem have 760,000 kcal of energy, this much is available to the primary consumers.
What is 76,000 kcal? (10% rule)
While carbohydrates contain Carbon, Hydrogen, and Oxygen, proteins are unique because they also contain this element.
What is Nitrogen?
What is Denaturation/Denaturization?
Humans and bears belong to this group because they eat both plants and animals.
Omnivores
Because animals cannot take it directly from the air, they must get this element by eating plants or other animals.
What is Nitrogen?
If a quaternary consumer were introduced to a system where producers had 760,000 kcal, it would only have this much energy available.
What is 76 kcal?
This type of chemical reaction bonds monomers together by removing a water molecule.
What is Dehydration Synthesis?
This term describes the ability of enzymes to only catalyze reactions with specific substrates.
What is Enzyme Specificity?
