I can’t see the diagram—could you upload it or describe what it shows (the order of fossils W, X, Y, Z on the timeline, their shapes/sizes, and any branching or labels)?
If you can’t upload, here’s how to check each statement against the diagram yourself:
- A (“Fossil X is one of the first organisms to eat plants”): look for X appearing at the first appearance of structures/traits associated with herbivory (e.g., teeth or mouthparts adapted to plant-eating) or emerging after plants become abundant. The diagram must show X appearing before other plant-eaters.
- B (“After fossil Z, organisms all gradually decreased in size”): look at the sizes of organisms shown after Z. If they consistently get smaller across the timeline after Z, B is supported; if sizes vary or increase, B is not supported.
- C (“Fossil W is one of the first organisms to have a movable jaw”): look for evidence that W is the first to show jaw structure (or W appears at the point where jaws first appear) compared with earlier fossils that lack jaws.
- D (“After fossil Y, there were few new types of organisms”): check the branching/diversification after Y. If there are few or no new branches/lineages after Y, D is supported; if many new types appear, D is not.
If you send the diagram or describe the order and key features, I’ll pick the best answer.
