All living and non-living things are linked together. Living things depend on non-living things such as sunlight, soil, water, and air to grow and survive. Green plants make their own food by using the sun's energy. Animals receive this energy when they consume plants.
Living things depend on sunlight, water, air, and soil
Some animals eat plants. These animals are called herbivores. Sheep, cows, and rabbits are herbivores.
Step 1: Click all 4 non-living things so the green plant can make food. Step 2: Feed the herbivore!
Some animals eat other animals' meat. They are called carnivores. Lions, tigers, foxes, and dogs are carnivores.
Human beings and some animals eat both plants and animals. They are called omnivores.
Lion (Eats meat only)
Food energy passes from plants to animals in the form of a long chain. This is called the food chain.
When plants and animals die, all the chemical substances in their bodies return to the soil.
Step 1: Green Plants Grow in Soil
There are millions of tiny living things in the soil. These tiny living things are called bacteria. Bacteria feeds on dead animals and plants. They break them down into tiny particles which mix with the soil. Plants repeat the cycle by absorbing these particles to make their food.
A food web consists of all the food chains. Each living thing is part of multiple food chains. All of the interconnected and overlapping food chains make up a food web.
All living things grow and change. When an animal or plant changes to fit its surroundings, we say it has adapted to its surroundings. The special body parts that a plant or animal develops to adapt to a particular place or living condition are called adaptations.
Animals are designed or adapted to live in their environment.
โข A tiger, for example, has sharp claws and teeth for tearing flesh.
โข A deer has horns for stabbing.
โข A mountain goat has hoofs for kicking and climbing rocks.
โข An eagle has a sharp beak and claws for catching mice and rabbits.
โข A chameleon changes colour so that it can blend in with its surroundings.
โข A bird has wings to fly.
โข A fish swims in water with its fins and tail.
Change the chameleon's surroundings or test how birds and fish move:
The beak of a humming bird is adapted for taking nectar from deep inside a flower.
Animals that live in very cold places, like polar bears, seals, and whales, have thick fur on their bodies. They have a thick layer of fat under their skins.
Most animals that live in very hot places, like camels, lizards, and snakes, rest during the day and look for food at night. They can store water in their bodies for a long time.
Plants that grow in very cold places have needle-like leaves. They make seeds inside cones. While plants that grow in very hot places have thick, fleshy stems that can store water. Their leaves are very small, and they have very deep roots. They have hard, waxy coats and thorns for protection.
