For example, in studying the unifying concept of system, as in ecosystem, students make connections between the physical and biological factors that affect mango yield. Mango yield is dependent on temperature, wind, water, and length of day and pollinators. Students describe, analyze, and give examples of how organisms are dependent on one another and their environments. In other words, there are direct and indirect relationships between organisms that allow them to survive. For example, a macadamia nut tree provides food and shelter for bees.
Bees help plants to reproduce through pollination.
Decomposers break down waste products and help provide nutrients to the soil. Synthesis Genetic Engineering DNA Fingerprinting Assess the benefits and drawbacks of biotechnology on the environment and society. Genetic Engineering Assess the genetic relationship between organisms. Fingerprinting Describe and explain the structure and functions of cells. Describe the process of photosynthesis and the transformation of energy.
