Explanation should include
- warm-blooded vs. cold-blooded (endothermic [homeotherms] vs. ectothermic [poikilotherms])
- skeletal systems (vertebrate and invertebrate)
- respiratory systems
- digestive systems
- reproductive systems
- muscular systems
- nervous systems
- size and body configuration (e.g., large body surface area to volume vs. small harsh environments such as the Arctic).
Process/Skill Questions:
- What is the definition of habitat?
- What are the similarities and differences between vertebrates and invertebrates?
- What is the difference between ectothermic and endothermic?
- What is the definition of ruminant? What advantages does a ruminant animal have over animals with other digestive systems?
- How have species adapted to survive in different environments?
- How is reproductive success based on habitat availability?
- How does an animal’s role in the ecosystem influence its adaptations?
- What advantages do different locomotion systems give to select animals?
- How might the anatomy of an animal indicate its role in the ecosystem or position on the food chain?
