Biotics and Abiotics List what you found in the dirt. What was alive or was once alive? What was not (or never) living? Biotics (a living thing)Abiotics (a non-living thing)

Biotics and Abiotics Biotic - A living thing Examples- Abiotic - a non-living thing Examples-

Producers, Consumers, and Decomposers All biotics are living things, and all living things need energy to survive. People are living things. Where do you get your energy from?

Producers, Consumers, and Decomposers Part I: Where Do Plants and Animals Get Their Energy? What did you have for lunch yesterday. List responses on the board. Write the words plant and animal on the board. Ask students to sort the food items into these two categories. For example, a lunch consisting of a cheeseburger, fries, and milk would be sorted this way: plant animal buncheese lettuce hamburger tomato milk ketchup French fries

Producers, Consumers, and Decomposers Food : plant animal

Producers, Consumers, and Decomposers Why do we need to eat? Where do cows get the energy they need to build muscle and produce milk? Where do plants get the energy they need to make leaves, like the lettuce we eat? Open up your chromebooks: Now it’s time to explore an Energy Flow Web activity that will answer these questions.Energy Flow

Producers, Consumers, and Decomposers Where do plants get the energy they need to grow? What do plants use the sun's energy to manufacture? What do plants use most of their energy for? How much of the energy that the plant captures through photosynthesis ends up stored as starch in the kernel? How does the cow use the energy from the corn? How much of the energy stored in the corn gets passed on to you in burgers? For what do you use the energy in the burgers? How would eating more plants help us better feed the many people in the world? What else besides energy do we get from plants and animals? When we eat them? (Answers: vitamins, minerals, and other nutrients needed to build body parts and keep the body running smoothly)

Producers, Consumers, and Decomposers What we’ve figured out is that all living things (biotics) need energy to survive. All living things can be divided into one of the following three groups, based on how they get their energy.

Producers, Consumers, and Decomposers A producer is a living thing that gets it’s energy from the sun and makes its own food through photosynthesis. What is photosynthesis? PhotosynthesisPhotosynthesis is a process where plants use light from the sun to turn air and water into food (sugars and carbohydrates.)

Producers, Consumers, and Decomposers A consumer is a living thing that needs to eat their food to get energy. There are three different types of consumers. Herbivores only eat food from plants Carnivores only eat food from other animals (meat) Omnivores eat food from plants or other animals.

Producers, Consumers, and Decomposers A decomposer is a living thing that eats dead things, turning those dead things in dirt or soil. Decomposer Video /decomposers/

Producers, Consumers, and Decomposers What do decomposers eat? What do decomposers do with the energy they get from eating dead things and waste material from living things? What important role do decomposers play in our environment? (Be sure to point out the role decomposers play in returning nutrients back to the soil.) Based on what you learned in the Energy Flow Web activity, what percentage of the energy stored in dead plants and animals do you think is available to the decomposers that eat them?Energy Flow What rule can we make about the percentage of energy that's passed on from one organism to another in a food chain?

Producers, Consumers, and Decomposers In the journal section of your notebook, make a chart and list types of living things you think would fit into each category: Producers Consumers Decomposers

Vocabulary Biotic - A living thing Abiotic - a non-living thing Producer - a living thing that gets it’s energy from the sun and makes its own food through photosynthesis. Consumer - a living thing that needs to eat their food to get energy. Decomposer - a living thing that eats dead things, turning those dead things into dirt or soil. Photosynthesis - a process where plants turn light from the sun into food.

Food Chain A food chain is a flow of energy in an ecosystem from producer to primary consumer to secondary consumer.

Predator/Prey A predator is an animal that hunts another animal for food. The animal that gets caught or hunted for food is the prey. In a food chain, the prey that eats a producer is the primary consumer, and the predator that hunts its prey is a secondary consumer. In this example, a mouse is the prey and the owl is the predator.

Energy Pyramid An energy pyramid is a diagram that shows the amount of energy at each level of the food chain.

Vocabulary Food Chain - The flow of energy in an ecosystem from producer to primary consumer to secondary consumer Predator - An animal that hunts another animal for food Prey - Animal caught or hunted for food Energy Pyramid - A diagram that shows the amount of energy at each level of the food chain

Vocabulary Population - A group of organisms of the same species in an ecosystem Communities - A group of organisms of different species in an ecosystem Food Web - Interconnected food chains with many food energy paths in an ecosystem

Food Web When food chains begin to interconnect, food webs form. A food web shows how communities, different organisms in an ecosystem all have a function and are dependant on each other. Here’s an activity where you can make a web Here’s a game about food webs you can try

BrainPOP Here’s a video review of food chains, food webs, and how producers, consumers, and decomposers are all interconnected in an ecosystem. Here’s a fun food web game to play with a friend.

Adaptations could be physical changes to the animal’s body or behavioural changes in how an individual animal or a society do things in their daily lives.
