Ecosystem

An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscapes, work together to form a bubble of life.

Matter and Energy

Matter is transported into, out of, and within systems.

• How does energy/matter cycle through an ecosystem?
• What does a plant need to grow?
• How does its structure support the process?
• What role do plants play within an ecosystem?

Cycles and Interactions

Cycles of Matter and Energy Transfer in Ecosystems through continuous interactions

• What do we know about matter and energy?

• What is the relationship between matter and energy and living things/systems?

• What is a cycle?

• Where do we see examples of cycles in the natural world?

Models

A model can be used to describe the components and  interactions within and between systems

• How can models help us describe the cycles and interactions within a system?
• What components both abiotic and biotic are essential to a healthy ecosystem? 
• In your model where do you see interactions? Is it a closed system or is it interacting with other systems? How does it work?
