FOOD WEBS Key Vocabulary: -Autotroph -Heterotroph -Producer -Consumer -Decomposer Teacher Actions: Model how students should set up their Interactive Notebook Student Actions: Students should set up their Interactive Notebook with

A decrease in the grass population would most immediately decrease the energy available for A. Mouse B. Hawk C. Snake D. Frog

How are autotrophs different than the power of heterotrophs? Autotroph- an organism that used solar energy to make chemical energy (i.e. palm tree, tulips, algae) Heterotroph- an organism the gets chemical energy from consuming other organisms. Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes.

How do changes in one population impact another? An increase in a population leads to an increase in the population that consume the organism and a decrease in the organisms food source population. Teacher Actions: Direct students to record information on the RH side of their notebook. Draw and example food chain including a minimum of 4 organism to illustrate the concept. Student Actions: Students record notes.

How do changes in one population impact another? A decrease in a population leads to an decrease in the population that consume the organism and a increase in the organisms food source population. Teacher Actions: Direct students to record information on the RH side of their notebook. Draw and example food chain including a minimum of 4 organism to illustrate the concept.

Quick Quiz 3 If the population of hawks in this area increases, their prey populations might decrease. Later, with fewer prey, the hawk population might decrease. The prey populations might then increase. This is an example of A. an ecosystem that is completely out of balance B. how ecosystems maintain stability over time C. interaction between biotic and abiotic factors within an ecosystem D. ecological succession in an ecosystem Teacher Actions: Use Quick Quiz strategy to assess student understanding.

What are the pieces of a food web? Producer- an organism that makes all of the energy Consumer- an organism that must eat other organisms to get energy Decomposer- eat dead and decaying matter Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes. https://www.sheppardsoftware.com/content/animals/kidscorner/games/producersconsumersgame.htm https://www.sheppardsoftware.com/content/animals/kidscorner/games/producersconsumersgame.htm

1. An increase in the owl population will lead to a (an increase/a decrease) in the rabbit population. 2. An increase in the owl population will lead to (an increase/ a decrease) in the grass population. 3. How will an increase in the owl population impact the mushroom population?

Autotrophs are organisms that use solar energy to make chemical energy. Heterotrophs are organisms the get chemical energy from consuming other organisms. Changes in a one organisms population impacts the rest of the community. An increase in a population leads to an increase in the population that consume the organism and a decrease in the organisms food source population. An decrease in a population leads to an decrease in the population that consume the organism and a increase in the organisms food source population. Teacher Actions: Cold call students to read the key points to the class Student Actions: Students use a highlighter to annotate the key points of the lesson
