E Biology — Unit 1 Life processes oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo Bl ~ | We can sort objects into three groups: e Living things (alive): animals, including humans and plants, are living things. They eat, move, have young and grow. e Not alive (dead): these things were once alive. For example, twigs were once part of a living thing. Bones were once part of a living thing that moved, had young, grew and needed food and water. e Never been dlive: these things have never been alive, for example, things made from plastic, stone, metal or glass. They have never moved, had young, grown or needed food and water. \. =4 a Sort these objects into three groups: alive, not alive, never been alive. b Add your own examples to the groups. tree plastic bottle ¢ What kind of scientific enquiry Hint: Ask yourself — activity is this?

Animals and plants grow. All animals start as young. We call human young, babies. Plants start as seeds and grow. Something that was once alive or that has never lived, does not grow like living things..

Eating the right foods helps the body to heal (get well) better after being ill or injured. e Animals get their foods from plants or other animals. \ J Breakfast gives you energy to Write answers to these questions. start the day! a Why do animals, including humans, need nutrition? b What did you have for breakfast?

Animals and plants need food and water (nutrition) to stay alive. Plants make their own food. Animals must find food. Different animals feed on (eat) different foods, such as grass, seeds, nuts, fruits, leaves and other animals, including insects, fish and birds. Some animals eat only one type of food. For example, the giant panda mostly eats bamboo shoots and stems. » giant pada eating bamboo Animals, such as goats, eat many types of plants. They eat leaves, grass, vegetables and even flowers. Some animals eat other animals. Frogs, for example, feed on flies and insects. Some animals eat plants and animals. The three-toed sloth, for example, eats leaves, fruits, slow-moving animals and bird’s eggs. , Humans can also eat frogs eat flies and other insects plants and animals. a Choose an animal and do research. What does it eat — plants, animals, or both? How does the animal move?

You now know that all living things need to carry out these four life processes: e Movement — all living things move. e Nutrition — all living things need food and water. glewitnlecall e Growth —all living things grow. Reproduction — all living things have young like themselves. Reproduction is the process by which living things produce young, called offspring. A grown-up animal is called an adult. snake with its hatchling Adult animals have babies. These babies are called offspring. Human parents are adults. Children are their offspring. Look at the pictures of adult animals and their — offspring. The offspring have special names. panda bear with its cub Look at these pictures of adult animals. Find Adult humans reproduce out what their offspring are called. Some and have offspring. have funny names! You are an offspring. At T You were once a baby. Bring photos to school and put them in your book to show what a porcupine human baby looks like.

A life cycle is a diagram (model) that shows the main stages of the life of a living thing. Scientists make models that help to explain ideas. They use the life cycle to show what happens in the life of a plant or animal. In the model of a life cycle (diagram) below, the salamander lays eggs. Each egg changes into a larva, before becoming an adult. This is an example of metamorphosis. moult larva newly hatched larva a Above is the life cycle of a 7N dragonfly (an invertebrate). It is in the wrong order. b Use modelling clay to make a model of this life cycle, but make ” life cycle growing sure it is in the correct order. bfa larva c Write these labels next to each eggs laid salamander in water part of your model life cycle: »_i | adult €ggs larva moult A% Did you know that when a dragonfly larva moults, it ).
