NGSS.5-LS. LIFE SCIENCE
5-LS2. Ecosystems: Interactions, Energy, and Dynamics - Students who demonstrate understanding can:
5-LS2.DCI. Disciplinary Core Ideas
LS2.A: Interdependent Relationships in Ecosystems
LS2.A:1. The food of almost any kind of animal can be traced back to plants. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants. Some organisms, such as fungi and bacteria, break down dead organisms (both plants or plants parts and animals) and therefore operate as “decomposers.” Decomposition eventually restores (recycles) some materials back to the soil. Organisms can survive only in environments in which their particular needs are met. A healthy ecosystem is one in which multiple species of different types are each able to meet their needs in a relatively stable web of life. Newly introduced species can damage the balance of an ecosystem. (5-LS2-1)
NGSS.5-PS. PHYSICAL SCIENCE
5-PS3. Energy - Students who demonstrate understanding can:
5-PS3-1. Use models to describe that energy in animals’ food (used for body repair, growth, motion, and to maintain body warmth) was once energy from the sun.
