What Are Some Roles of Living Things?
Transcript of What Are Some Roles of Living Things?
That means the living things in an ecosystem depend on one another.
The swollen thorn acacia tree and a type of stinging ant are interdependent. The ants live in the tree. They eat a sugary liquid in the tree's leaves. The ants help the tree by protecting it. When another kind of animal starts eating the tree, many ants sting the animal. The ants drive the animal away.
In Africa, the Nile crocodile and a bird called the Egyptian plover help each other. The crocodile lets the bird come into its mouth. There the bird eats little animals on the crocodile's gums. This is good for both animals. The bird gets a meal. the crocodile gets its teeth cleaned!
Tell how these things are interdependent.
Every living thing has a job to do.
Plants have the job of being producers.
A producer is a living thing that makes its own food. Plants use energy from the sun to make food. Plants use the energy from their food to grow.
When an animal eats a plant, the energy in the plant moves into the animal. Animals are consumers. Consumers get energy by eating plants or by eating other animals that eat plants.
All consumers depend on producers for food
Relationships in an Ecosystem
2. Tell how plants use the food they make from the energy in sunlight.
Animals are consumers. They eat producers (plants) or other animals for food.
Write this sentence on the lines for questions 3. on page 172.
3. Tell how animals get food. Use the words
in your answer.
Sometimes living things help each other find shelter. For example, a squirrel using a tree for shelter. The tree is a living thing that helps another living thing (the squirrel) by giving it shelter (a place to live.) Birds also live in trees.
Trees also provide shelter in the form of shade for ferns that grow on the ground under trees.
Some animals provide shelter for other animals. Woodchucks dig tunnels underground. They live there for a while and then move on. A skunk or rabbit may live in the same tunnel next.
Shelter is another basic need of living things.
Reproduction is the process of making more of one's own kind. Some living things help other living things carry out reproduction.
Pollinators and Seed Dispersal
How do plants depend on animals to reproduce?
What Are Some Roles of Living Things?
1. Swollen thorn acacia tree
Provides food and shelter for the ants.
a. protect the tree by stinging other animals that try to eat the tree.
b. Provides food for the bird
Cleans the crocodile's teeth and gums.
Plants use the energy in sunlight to make food. Plants are
Plants use energy from food to
Some food is
in roots, stems, and leaves.
4. Give three examples of living things that provide shelter for other living things.
Trees provide homes for birds, squirrels, and other animals.
Trees provide shelter for plants, such as ferns and mosses.
Woodchucks dig tunnels that are used by skunks and rabbits.
From what other things might shelter protect animals?
Shelter also protects animals from heavy rain and cold.
Write this answer at the bottom of page 173.
Many plants reproduce by making seeds. For a plant to make seeds, pollen must move from one part of a flower to another part, or from one flower to another flower. Wind and water can carry pollen. Insects and birds can carry pollen, too. An animal that carries pollen is called a pollinator.
Pollinators feed on pollen. They carry pollen from flower to flower. When pollen touches the right part of the flower, seeds begin to form.
5. List three ways that pollen is moved from flower to flower: (Write this on page 174 at number 5.)
Some plants depend on animals to carry their seed to new places. Seed dispersal is the scattering or carrying away of seeds from the plant to a new place. Some seeds get caught in the fur of animals. The animals may go a long way before the seeds fall off.
Some plants grow fruit. Seeds grow inside the fruit. Animals eat the fruit and drop the seeds of leave them behind in their waste (that's poop :-)) If seeds fall in rich soil and get water, they will grow.
6. Living things that use energy in sunlight to make food are called:
Living things in an ecosystem depend on one another for basic needs such as food, shelter, and protection. How do animals help in seed dispersal?
Seeds get caught in an animal's fur and are carried away. animals also eat fruit with seeds in it and leave them in their waste.
This is the answer to the Summary Question on page 175
from flower to flower.
to new places.
Plants depend on animals to reproduce.
