Bring your notebook, agenda and pencil to your assigned seat Complete Tuesday’s warm up now!! YOU ARE SILENT, WORKING WHEN THE BELL RINGS!!!
Begin new standard 6.L.2.1 Food Chains and Food Webs Read unpacked standard Notes on producers, consumers, decomposers in food webs and food chains
Label Next Available Page: 6.L.2.1 Producers, Consumers,and Decomposers in Food Webs and Chains Number page to match Table of Contents entry
To understand the flow of energy on Earth To understand the different levels of energy as it is transferred through food chains (webs) To appreciate the importance decomposers and the recycling of nutrients To understand the cycling of matter on Earth (oxygen, nitrogen, carbon, water)
You will receive a handout…this will be completed today and turned in at the end of class
Energy flows through ecosystems on Earth in only one direction Flow of energy: from the sun to producers to consumers to decomposers
ECOSYSTEMS: all the living things (plants, animals, and organisms) interacting with one another in a given location along with their non-living environments Aquatic Ecosystems Marine Ecosystems
How do all the living things (plants, animals, and decomposers) obtain their energy in their ecosystem? They either produce their own energy, consume other organisms, or decompose dead and organic matter Aquatic Ecosystems Marine Ecosystems
We will begin with a short video on Study Jams to introduce this unit in science Answer the questions on your worksheet
ms/science/ecosystems/food-chains.htm ms/science/ecosystems/food-chains.htm
1. What is a food chain? 2. How is energy transferred within a system and between organisms? 3. Why are decomposers important to this transfer of energy?
Using the information in the following slides, check to see how successful you were in recording information from the video questions We will review everything now during whole group discussion
PRODUCERS: Make their own food through photosynthesis This food is energy for the plant and higher level consumers that eat plants Includes: all green plants and algae
CONSUMERS: eat other organisms
Primary Consumers =Eat Producers (known as herbivores) Secondary Consumers =Eat Primary Consumers (carnivores that eat the herbivores) Tertiary Consumers = Eat Secondary Consumer (carnivores that eat other carnivores)
CONSUMERS: 3 TYPES
1. HERBIVORES: animals that mainly eat PLANTS like leaves, grass, flowers, seeds, roots, fruits and more Herbivore Examples (write down 3) Deer Horses Rabbits Cows Bees Sheep Grasshoppers
2. CARNIVORES: animals that eat mainly meat including insects and animals Carnivores examples (write 3) Felines (lions, tigers) Eagles, hawks, owls Sharks Frogs Spiders
3. OMNIVORES: organisms that eat plants and animals Omnivore Examples: Humans (not vegetarians) Most Bears Raccoons Most primates (apes and monkeys) Seagulls
DECOMPOSERS: eat dead plants and animals and break them down (decompose) Decomposers return nutrients back to the environment. Examples include: Fungi Bacteria earthworms
Food chains: show how plants and animals get connected together by the things they eat. Within the chain, all organisms depend on one another to survive
Use the space on your worksheet draw a simple food chain You must clearly show and label: A producer A primary, secondary and tertiary consumer A decomposer
energy Energy returned to the environment energy
Food Webs: Much more complex than a simple food chain Shows complex feeding relationships within the communities found in ecosystems
