This promising practice lesson introduces students to the world's deserts, as well as the symbiotic relationships that take place there. Plants and animals must also have adaptations that allow them to survive in the desert environment. This lesson also does a good job of discussing some of these adaptations. (author/cb)

|
| Benchmarks (6 - 8) |
|
| C. | Describe interactions of matter and energy throughout the lithosphere, hydrosphere and atmosphere (e.g., water cycle, weather and pollution). |
|
| Grade Level Indicators (Grade 7) |
|
| 8. | Describe how temperature and precipitation determine climatic zones (biomes) (e.g., desert, grasslands, forests, tundra, alpine). |
|
|
| Life Sciences | |
|
| Benchmarks (3 - 5) |
|
| B. | Analyze plant and animal structures and functions needed for survival and describe the flow of energy through a system that all organisms use to survive. |
| C. | Compare changes in an organism's ecosystem/habitat that affect its survival. |
|
| Benchmarks (6 - 8) |
|
| B. | Describe the characteristics of an organism in terms of a combination of inherited traits and recognize reproduction as a characteristic of living organisms essential to the continuation of the species. |
| C. | Explain how energy entering the ecosystems as sunlight supports the life of organisms through photosynthesis and the transfer of energy through the interactions of organisms and the environment. |
|
| Benchmarks (9 - 10) |
|
| E. | Explain how evolutionary relationships contribute to an understanding of the unity and diversity of life. |
|
| Benchmarks (11 - 12) |
|
| A. | Explain how processes at the cellular level affect the functions and characteristics of an organism. |
|
| Grade Level Indicators (Grade 5) |
|
| 4. | Summarize that organisms can survive only in ecosystems in which their needs can be met (e.g., food, water, shelter, air, carrying capacity and waste disposal). The world has different ecosystems and distinct ecosystems support the lives of different types of organisms. |
| 5. | Support how an organism's patterns of behavior are related to the nature of that organism's ecosystem, including the kinds and numbers of other organisms present, the availability of food and resources, and the changing physical characteristics of the ecosystem. |
|
| Grade Level Indicators (Grade 7) |
|
| 2. | Investigate how organisms or populations may interact with one another through symbiotic relationships and how some species have become so adapted to each other that neither could survive without the other (e.g., predator-prey, parasitism, mutualistism, commensalism). |
|
| Grade Level Indicators (Grade 8) |
|
| 3. | Explain how variations in structure, behavior or physiology allow some organisms to enhance their reproductive success and survival in a particular environment. |
|
| Grade Level Indicators (Grade 10) |
|
| 14. | Relate diversity and adaptation to structures and their functions in living organisms (e.g., adaptive radiation). |
|
| Grade Level Indicators (Grade 12) |
|
| 2. | Explain why specialized cells/structures are useful to plants and animals (e.g., stoma, phloem, xylem, blood, nerve, muscle, egg and sperm). |

|
| The characteristics of organisms (Grades Kindergarten - 4) |
|
| Organisms have basic needs. For example, animals need air, water, and food; plants require air, water, nutrients, and light. Organisms can survive only in environments in which their needs can be met. The world has many different environments, and distinct environments support the life of different types of organisms. |
|
| Each plant or animal has different structures that serve different functions in growth, survival, and reproduction. For example, humans have distinct body structures for walking, holding, seeing, and talking. |
|
| Structure and function in living systems (Grades 5 - 8) |
|
| Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle. Different tissues are in turn grouped together to form larger functional units, called organs. Each type of cell, tissue, and organ has a distinct structure and set of functions that serve the organism as a whole. |
|
| Diversity and adaptations of organisms (Grades 5 - 8) |
|
| Biological evolution accounts for the diversity of species developed through gradual processes over many generations. Species acquire many of their unique characteristics through biological adaptation, which involves the selection of naturally occurring variations in populations. Biological adaptations include changes in structures, behaviors, or physiology that enhance survival and reproductive success in a particular environment. |
|
| Interdependence of organisms (Grades 9 - 12) |
|
| Organisms both cooperate and compete in ecosystems. The interrelationships and interdependencies of these organisms may generate ecosystems that are stable for hundreds or thousands of years. |
