Part One: Energy Pyramid Consider the following description of an ecosystem.
There are many cacti, as well as sagebrush, and a few low trees. There are tracks of a desert fox
leading to and from a potential burrow. Sand grouse feathers are present at the mouth of the
burrow. Termites are feeding on a fallen tree. Many birds called sand grouse are eating the
termites.
Think about the trophic levels in this ecosystem. Describe how you would create an energy
pyramid to model the flow of energy in this ecosystem.

In dna, only the_ varies from one nucleotide to another. base phosphate sugar amino acid

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f

If a baby girl guinea pig looks almost identical to its mother, does this then mean that it inherited more alleles from its mother? explain. (hint: think about the vocabulary words dominant and recessive.)
