Year 4 Science Habitats, change and food chains: summary and key words
Part of the Year 4 Science habitats, change and food chains chapter. Chapter overview · whole chapter on one page
Chapter summary
| Skill | Method |
|---|---|
| Changes in a habitat | Environments change naturally, or because of people. Some changes are dangerous to living things. |
| Dangers to living things | A change can take away water, food, or a place to hide and nest. A fall in number is the before number minus the after number. |
| Food chains | A food chain starts with a producer, a plant. Arrows point from the food to the eater. |
| Predators and prey | A predator hunts and eats other animals. Prey is the animal that is eaten. |
| Effects along a chain | A chain with five living things has four arrows. Removing a link affects the living things that depend on it. |
