Food Chains, Food Webs and an Introduction to Biodiversity

Look at the food chain below. For the GRASS, please select any of the words below that correctly describe this organism. Note: You will have more than one word marked.

• Autotroph
• Producer
• Decomposer
• Heterotroph
• Primary Consumer

Look at the food chain below. For the FROG, please select any of the words below that correctly describe this organism. Note: You will have more than one word marked.

• Heterotroph
• Secondary Consumer
• Autotroph
• Decomposer
• Primary Consumer

Using the food chain provided in the first 2 questions, choose the organism that belongs in the 1st TROPHIC LEVEL of the energy pyramid below.

• grasshopper
• frog
• snake
• grass

Using the food chain provided in the first 2 questions, choose the organism that belongs in the 2nd TROPHIC LEVEL of the energy pyramid below.

• grasshopper
• frog
• snake
• grass

Using the food chain provided in the first 2 questions, choose the organism that belongs in the 3rd TROPHIC LEVEL of the energy pyramid below.

• grasshopper
• frog
• snake
• grass

Using the food chain provided in the first 2 questions, choose the organism that belongs in the 4th TROPHIC LEVEL of the energy pyramid below.

• grasshopper
• frog
• snake
• grass

Using energy pyramid from above (with all 4 organisms labeled inside of each trophic level), if the grass had 25,000 Kcal of energy ,approximately how much would you expect of that energy to be stored in trophic level 4?

• 25 Kcal
• 250 Kcal
• 2,500 Kcal
• 25,000 Kcal

Fungus is an organism not drawn in the above food chain although it has a very important role. Describe an important role of organisms such as fungi and bacteria:

For the FUNGUS, please select any of the words below that correctly describe this organism. Note: You will have more than one word marked.

• Autotroph
• Decomposer
• Heterotroph
• Producer
