A group of organisms that live in the same area and interact with each other and their environment.
What is a community?
100
This type of reaction can form a bond between two monomers.
What is dehydration synthesis?
100
This organelle is only found in eukaryotes, and contains the cell's genetic material.
What is the nucleus?
100
______ must be consistently resupplied to an ecosystem, as it is continuously lost as heat and cannot be recycled.
What is energy?

Labeled "1" in the diagram, these intermolecular forces give rise to the many unique properties of water.
What are hydrogen bonds?
200
The maximum population of an organism that an ecosystem can support.
What is the carrying capacity?
200
Starch, which is a polymer of glucose, is an example of this type of macromolecule that only includes the elements C, H, and O.
What is a carbohydrate?
200
These organelles produce proteins.
What are ribosomes?
200
This rule helps to explain why food pyramids don't contain more than five trophic levels.
What is the 10% rule?
200
This property of water allows insects to be able to glide across a pond, or for a large number of drops to stack on a penny.
What is its high surface tension?
300
One example of this relationship occurs in the relationship between a remora fish and a shark, where the remora attaches itself to the shark and eats scraps of food left behind by the shark's feeding, benefiting from the shark's presence without harming it, while the shark is essentially unaffected by the remora's presence.
What is commensalism?
300
Examples of these biomolecules include cholesterol and triglycerides.
What are lipids?
300
One piece of evidence for this theory is that mitochondria and chloroplasts have their own DNA.
What is endosymbiont theory?
300
The cycle of this element does not include an atmospheric component.
What is phosphorus?
300
This functional group is acidic and often negatively charged.
What is a carboxyl group (carboxylic acid)?
400
One example of this type of population-limiting factor is a disease that spreads more easily when the population is high.
What is a density-dependent factor?
400
This nucleotide is only found in RNA.
What is uracil (U)?
400
In this type of cell transport, water is transferred from an area of high water concentration to an area of low water concentration?
What is osmosis?
400
One step in this process involves a dramatic increase in the amount of decomposers present, due to an excess of nitrogen, that ultimately leads to the death of fish and other aquatic organisms.
What is eutrophication?
400
This functional group is the only one we studied that is nonpolar.
What is a methyl group?
500
Eagles produce just a few offspring and spend significant resources in their care. Eagles also have fairly stable populations and have evolved to better compete for limited resources. They are an example of this type of population selection.
What is K-type selection?
500
These are held together by hydrogen bonds between non-adjacent amino acids in the polypeptide backbone.
What are protein secondary structures?
500
This process occurs when a cell creates a vesicle from its own membrane to import a substance from the outside.
What is endocytosis?
500
The cycle of this element depends on bacteria that can "fix" the element from the atmosphere, making it available to other organisms.
What is nitrogen?
500
The basic properties of this functional group can lead it to be positively charged.
What is an amino group?
