17 lut 2023 · A food chain refers to a linear sequence of organisms showing how energy or nutrient flows through an ecosystem when one organism consumes another for its survival. It provides information about which species eats which other species in nature.
To understand food chains and food webs, we must start with where the energy begins. Sunlight is energy, and plants use this energy to turn water and carbon dioxide into plant food. This process is called “photosynthesis”. Plants also need minerals and nutrients. They get these from the soil when their roots take up water.
Video summary. This short film for KS1 pupils describes food chains, explaining what consumers and producers are, and what can happen if a food chain is disrupted. It explores common food...
