Monday, Aug. 17th LT: I can explain how feeding relationships work in an ecosystem. WU: Explain what an ecosystem is.

Warmup 8-15-16 On your warmup sheet, you will answer questions 1-4 on the handout provided. Write the answer only! You do not have to write the question. Do no write on my handout!

1. All the living things in an area and the nonliving things they interact with.

Living – hawk, cactus, plants, animals, snake 2. Living – hawk, cactus, plants, animals, snake Nonliving – air, sunlight, sand

Population because it is all the deer which means one type of animal 3. Population because it is all the deer which means one type of animal

Population: a group of the same organisms 4. Population: a group of the same organisms Community: the different kinds of organisms in an ecosystem

Feeding Relationships What are some words you’ve heard before that would describe a feeding relationship in an ecosystem?

When setting up a food web: The arrow always goes the direction in which the energy is being transferred. Here’s an example: Spider and fly…who eats who? Will the arrow be pointing down or up? Spider Fly

Please clear everything off your desk

Instructions Read the cards and become familiar with the organisms and their feeding relationships (who eats who?). Using the arrows provided, show the feeding relationships between the organisms Every organism should be included. If an organism is involved in two or more feeding relationships, all the relationships should be indicated with arrows.

In an ecosystem, many organisms survive by eating other organisms In an ecosystem, many organisms survive by eating other organisms. The benefits of the food eaten by one organism can then move to another organism an another as each one is eaten. Can anyone tell me what we call the path that food takes from one organism to another? Food Chain

Name one food chain that you can find in your food web Name one food chain that you can find in your food web. Planktonic algaeBrine ShrimpCalifornia gullcoyotedecomposer

Many of the organisms in your feeding-relationship projects are connected with more than one arrow. One organism, phalaropes, eat multiple organisms. Brine shrimp, are eaten by many organisms. When you connect all the organisms with arrows, the arrows cross each other in a complex way. Can anyone recall what we call this diagram that shows all the feeding relationships? Food Web

Which organisms in the food web do not eat any other organisms? The algae How can they survive without eating? Sun, They make their own food What do we call organisms that make their own food? Producers

They eat other organisms Producers like algae make their own food, but animals, like brine shrimp and gulls, don’t make their own food. How do animals get their food? They eat other organisms

What do we call organisms that eat other organisms? Consumers Consumers can be classified even more specifically. What do we call consumers that eat producers? Primary Consumer or 1st level What do we call consumers that eat primary consumers? Secondary Consumers or 2nd level What do we call consumers that eat secondary consumers? Tertiary or (Third-level) Consumers

Some organisms are never eaten by consumers, but instead die natural deaths. Dead organisms are broken down and consumed by microorganisms. How do we classify these microorganisms? Decomposers Organisms like bacteria and fungi are decomposers. Everything that is not eaten by a consumer is eventually eaten by decomposers.

KEY POINT Everything at every level eventually dies and is decomposed. Decomposers are connected to everything in the food web.

Notebook page 11 You will have 5 minutes to individually work on this assignment. After 5 minutes you will turn to your neighbor to discuss. Redraw your answer at the bottom of page 11

Exit Slip Due by the end of class Turn in to your class tray when finished Level 0 while completing the assignment so everyone can focus, please!

Warmup 8-18-16 1. Use the words producer, secondary consumer, tertiary, primary consumer, decomposer to fill in the following energy pyramid Grass  cricket  snake  hawk  bacteria Identify the decomposer Identify the producer Which organism has more energy available– grass or hawk True or false: Energy flows from snake to cricket.

Wednesday, Aug. 19th LT: I can explain how water collects in a watershed. WU: What do you think a watershed is? (If you’re having trouble coming up with a definition, think about what you think a “toolshed” is, then use that info to decide what you think a “watershed” is)

Let’s take a look at our lab roles: Materials Manager- gets all materials, only one out of seat, in charge of clean-up process Facilitator- in charge of watching time, keeps group quiet, keeps notes for the group Technician- performs the lab and Director- reads directions, keeps group on task

Thursday, Aug. 20th LT: I can explain how water collects in a watershed. WU: Explain what the statement “Everything upstream, ends up downstream” means. Think about our models from yesterday.

Place your colored article in the center of the table. Place the chart you filled in in your science folder. Place your science warm up in your folder if you haven’t done so already. Stack your table’s science folders in the center of your table as well.

Friday, Aug. 21th LT: I can explain estuaries. WU: What is an estuary? A partially enclosed body of water where freshwater and saltwater meet.
