The Cycle of Life: Matter and Energy in Ecosystems Review

The video tutorial explores the concepts of matter and energy in organisms and ecosystems. It explains how plants use photosynthesis to convert sunlight, water, and carbon dioxide into glucose and oxygen, making them producers. Consumers obtain energy by eating other organisms. The video also covers the digestion process and chemical respiration. It introduces ecosystems, food chains, and food webs, illustrating the flow of energy and matter. An interactive exercise encourages viewers to create a food web and identify producers and consumers in a chosen ecosystem.

List the materials that plants rely on for photosynthesis.

What is the process called through which plants convert sunlight, water, and carbon dioxide into food?

Explain the role of producers in an ecosystem.

Describe the process of digestion and its importance for nutrient absorption.

What is a food chain and how does it illustrate the flow of energy in an ecosystem?
