Lesson Outline• Plants and Photosynthesis• Ecosystem• Vocabulary• Food Chain• Applets• Poster Board Demonstration

How does an animal get energy from a

plant?• It all begins with PhotosynthesisPhotosynthesis is the process of converting light energy to chemical energy and

storing it in the bonds of sugar.

Plants need only light energy, CO2, and H2O to make sugar.

The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment

involved in photosynthesis

Ecosystem• An area where all the species of

plants and animals depend on each other for survival.

In an Ecosystem!

Producers: green plants. All food chains start with them, because they can make food by photosynthesis.

Primary consumers feed primarily on plant material. They are

herbivores - eg rabbits, caterpillars,

cows, sheep, and deer

Secondary consumers feed primarily on animal material. They are carnivores - eg cats, dogs and

lions.

Omnivores eat both plants and animals - eg bears and humans.

Prey are the organisms that predators feed on. Examples of

predator and prey species are: fox and rabbit; blue tit and caterpillar;

wolf and lamb.

Predators kill for food. They are either secondary or tertiary

consumers - eg polar bears, golden

eagles.

• Scavengersfeed on dead animals . They perform a useful cleaning-up function. Examples are crow, vulture, buzzard and hyena.

Decomposers feed on dead and decaying organisms and on the undigested parts of plant and

animal matter in the faeces. They do not eat the food like scavengers, as they have no mouth-parts. Instead they break down solid matter into liquids which they can absorb. Examples:bacteria and

some fungi.

Additional Notes• A variety of plants provides habitats and

food for a wide range of animals. They also provide humans with many different raw materials, medicines and food. We need them to keep the balance of gases in the atmosphere healthy by using carbon dioxide and producing oxygen, and they make the world a nicer place by the beauty of their shapes, scents and colours

Additional Notes• there is a great choice for use as raw

materials; • they provide different sources of food for all

kinds of animals; • they ensure a variety of shelter for animals; • by using up carbon dioxide and producing

oxygen they help to keep the balance of gases in the atmosphere;

• they form a vital part of the beauty of our planet

Food Chain A food chain shows who eats what in a particular

ecosystem.
