Abiologist studying alpine wildflowers notices that two populations of similar species are able to occupy the same niches. however, species a is mostly found at lower altitudes, while species b is mostly found at higher altitudes. what has most likely caused the realized niches of these two wildflower populations to be smaller than their fundamental niches? a. competition has restricted the ranges of both species. b. the species are involved in a mutualistic relationship. c. species a is capable of growing faster than species b. d. species b requires fewer resources than species a.

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
