1:The Food Chain Gizmo shows a food chain with hawks, snakes, rabbits, and grass. In this simulation, the
hawks eat snakes, the snakes eat rabbits, and the rabbits eat grass.
1. Producers are organisms that do not need to eat other organisms to obtain energy.
A. Which organism is a producer in this food chain?
B. Where does the producer get its energy?
2. Consumers must eat other organisms for energy. Which organisms are consumers in this food chain?
MOVES
ADO REMOVE

The SIMULATION pane of the Gizmo shows the current population, or number of
each organism in the food chain.
1. What are the current populations of each organism?
Hawks Snakes Rabbits Grass

Skulls of (1) modern gorilla, (2) australopithecus afarensis, (3) homo erectus, (4) homo neanderthalensis, (5) homo sapiens based on the diagram, which of the following best describes ways in which the physical appearance of h. neandertalensis and h. sapiens differ? (2 points)

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
