New Jersey Standards

NJ.5.3.4. Life Science: Life science principles are powerful conceptual tools for making sense of the complexity, diversity, and interconnectedness of life on Earth. Order in natural systems arises in accordance with rules that govern the physical world, and the order of natural systems can be modeled and predicted through the use of mathematics.
5.3.4.B. Matter and Energy Transformations: Food is required for energy and building cellular materials. Organisms in an ecosystem have different ways of obtaining food, and some organisms obtain their food directly from other organisms.
Almost all energy (food) and matter can be traced to the Sun.
5.3.4.B.1. Identify sources of energy (food) in a variety of settings (farm, zoo, ocean, forest).
5.3.4.D. Heredity and Reproduction: Organisms reproduce, develop, and have predictable life cycles. Organisms contain genetic information that influences their traits, and they pass this on to their offspring during reproduction.
Plants and animals have life cycles (they begin life, develop into adults, reproduce, and eventually die). The characteristics of each stage of life vary by species.
5.3.4.D.1. Compare the physical characteristics of the different stages of the life cycle of an individual organism, and compare the characteristics of life stages among species.
5.3.4.E. Evolution and Diversity: Sometimes, differences between organisms of the same kind provide advantages for surviving and reproducing in different environments. These selective differences may lead to dramatic changes in characteristics of organisms in a population over extremely long periods of time.
In any ecosystem, some populations of organisms thrive and grow, some decline, and others do not survive at all.
5.3.4.E.2. Evaluate similar populations in an ecosystem with regard to their ability to thrive and grow.
