2The Needs of Animals Animals have 5 basic needs Food Shelter Oxygen/airWaterSpace
3Food One thing living animals need is food Living animals use different amounts of foodMany kinds of birds eat almost all day. Snakes may only eat once a week
4Plant EatersAnimals cannot make their own food. They need to find their food. Not all animals eat the same kinds of food. Some animals eat only plants or plant parts. Animals that eat only plants or plant parts are called plant eatersElephants or giraffes are examples of plant eaters. Some plant eaters are smaller.
5Animal eatersSome animals eat only other animals. An animal that hunts and eats other animals is called a predator. Foxes, dingos, snakes, and cats are all predators. Predators are a very important part to nature.Can you tell me why?
6PreyAnimals that have been eaten by predators are called prey.
7Omnivores Some animals eat both plants and animals Bears may eat fish, nuts or berries.Raccoons eat meat. They also eat fruits and seedsMost people eat both plants and meat
8Food ChainsThe plant, grasshopper, bird, and cat are each part of a food chain. Plants, animals which eat these plants, and animals which eat other animals form food chains.Think of each plant or animal as a link in a food chain. Each living thing is food for the next link in the food chainFood chains can have few or many links.
9Food Chains Continued… Lets look at an exampleA girl eating tomatoes and lettuce in a salad is a short food chainA longer food chain might start with a rabbit eating grass. The rabbit is eaten by a mountain lion. When the mountain lion dies, it is eaten by a vulture.
10Producer and ConsumerAny living thing which makes or produces its own food is called a producerThe next link in all food chains is a consumerA consumer is any living thing that must eat other living things for food. A consumer cannot make its own food. Every link that is added to a food chain after the first link is a consumer
11Consumer and Producer Continued… Suppose a shrimp eats some water plants. A small fish catches and eats the shrimp. A large salmon eats the small fish. Finally a boy catches and eats the salmon.Who is the producer?Who is the consumer?
12Living things and their needs A need is anything a plant or animal must have to stay aliveAnimals must have shelter, food, and water to live.Most plants must have food, water, and sunlight to live
13HabitatThe place where each plant or animal lives is called a habitat There are many kinds of habitats. What type of a habitat would a..Dog have?Fish have?Lion have?
14Habitat continued…Habitats may be small or large. Some habitats may be as small as a crack in a rock, other habitats may be as large as a whole forest.
16People affect habitats The number of people on the Earth keeps growing. There are billions more people now than there were a few hundred years ago. More people use more land. They use more water. People now live in places where only plants and animals used to live.
18People affect habitats People change the natural habitats of living things. Some changes may be harmful to the plants and animals. There may be less food and water for them to use. There may be less space for the plants and animals. Some changes may be helpful. People might stop the erosion of some soil and rocks.
19People affect habitats People need to be careful about changing habitats. They must conserve as many habitats as they can. Conserve means to use wisely.People conserve when they make wise decisions about how to use the land.
29Adapted Each living thing is adapted to live in a certain place Adapted means the living thing fits into its habitat. Its needs are met.
30Polar HabitatsSome parts of the world are very cold. These cold places near the North and South Poles are Polar areas.Snow and ice cover the polar areas most of the year.Animals that live here need a thick warm coat and lots of fat on their bodies to survive.
31Polar AreasAnother way that animals have adapted in polar areas is they grow a thick coat during the winter and then shed much of their fur in the summer months. Others also change color for camoflage
32Desert HabitatsA desert is a place that does not have much rain. Some deserts are hot and dry. Some are cold an dry. Living things in deserts are adapted to having little water. Most desert animals get their water from their food.
33Desert HabitatsMany desert plants and animals are small. Being small is one way they have adapted to live in the desert. Small living things need less water than large ones.
34Grassland HabitatsA grassland is a place where most of the plants are grasses. Many different kinds of animals live on grasslands. Some of the biggest land animals live here. Some of the fastest live here, too.
35Forest HabitatsThere are different kinds of forest habitats. Most forests have 4 seasons. These are called temperate forest. A temperate forest has many trees that lose their leaves in the fall.Forest animals are adapted to the change of seasons.
36Rain ForestsRain forests are very hot and wet habitats. Some rain forests are in South America and Africa.Plants grow well in rain forests. They grow well because of the heat and rain.Animals in rain forests are adapted to moving through the many plants. Monkey’s have long tails. Tree frogs have fee that are like suction cups
37Water HabitatsMuch of the earth is covered with water. A water habitat is any place filled with water in which plants or animals live.Many animals in the water move to find food and get away from predators. Other animals are attached to objects in the water. They get food as it floats past. These are ways that these animals have adapted to their habitat.
