Ancient Architects of the Forest
Hidden in the shaded corners of forests, draped across stone, and even tucked into city sidewalks, mosses and lichens quietly shape the world around us. These ancient organisms filter air and water, build soil, stabilize habitats, and support wildlife from tiny micro-animals to nesting birds. In this episode, we take a closer look at how these small but powerful lifeforms work together to create the foundation of entire ecosystems.
Standards
- 3-LS4-3. Construct an argument with evidence that in a particular habitat some organisms can thrive, struggle to survive, or fail to survive.
- 4-LS1-1. Construct an argument that plants and animals have internal and external structures that function together in a system to support survival, growth, behavior, and reproduction.
- 4-LS1-2 Use a model to describe that animals receive different types of information through their senses, process the information in their brain, and respond to the information in different ways
- 5-LS2 Ecosystems: Interactions, Energy, and Dynamics
- 7-LS1-6 Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.
- B-LS2-2. Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
- B-LS2-6. Evaluate claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions but changing conditions may result in a new ecosystem.
