1 Processes of Life (SC.F.1.2) The student describes patterns of structure and function in living things. (2)The student knows how all animals depend on plants

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

3 How does an animal get energy from a plant?
It all begins with Photosynthesis Photosynthesis 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.

5 Palisade mesophyll cell
The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment involved in photosynthesis                                                          Palisade mesophyll cell

6 Ecosystem An area where all the species of plants and animals depend on each other for survival.

7 In an Ecosystem! Food chain Producers Primary consumers
Secondary consumers Omnivores Predators Prey Scavengers Decomposers

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

10 Primary consumers feed primarily on plant material
Primary consumers feed primarily on plant material. They are herbivores - eg rabbits, caterpillars, cows, sheep, and deer

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

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

13 Prey are the organisms that predators feed on
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.

14 Predators kill for food
Predators kill for food. They are either secondary or tertiary consumers - eg polar bears, golden eagles.

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

16 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.

19 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

20 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

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