Key Questions

What do I already know about food chains and habitats?

I know that animals obtain their food from plants and other animals and can show this as a food chain. I know that most living things live in habitats that suit them and help to meet their needs.

How can we sort living things into different groups? How do classification keys work?

Animals can be put into one of two groups - vertebrates and invertebrates. Vertebrates can be grouped or classified in five ways: Fish, Amphibians, Reptiles, Mammals and Birds (FARM B). We can also use classification keys (a series of questions with yes/no answers) to help us work out what an animal might be. We look at the observable features of the living creature and its habitat to help answer these questions.

What are producers, predators and prey?

All food chains start with a green plant, which makes its own food (producer). Some animals eat these plants. These animals (prey) may be eaten by other animals. Animals which hunt and eat other animals are called predators.

What happens when environments change?

As the seasons change, the weather and plants in an environment will change. Humans can also change habitats e.g. when they drop litter or chop down trees. Some of the changes will have a positive impact on the living things in the environment but others are more negative and can lead to animals becoming endangered or extinct.
