Question

name: yasmine date: food web practice part 2: constructing a food: in the box below, construct a food web using the following animals: snake, corn, caterpillar, deer, crow, mouse, cougar, squirrel, microorganisms (decomposers). when constructing your food web, follow these directions: 1. draw an arrow (color matters = green=producer - yellow=1st cons, blue=2nd cons from each living thing below to each thing that eats it. 2. the first arrow in any food chain (between producer and primary consumer) should be green, the second (between primary consumer and secondary consumer) should be blue, the third (between secondary and tertiary consumer) should be red and the fourth should be yellow. 3. do not draw pictures. only use animal names. draw your lines so they bend around the animal names. this will make your food web easier to read when you finish.

Explanation:

1. First, identify the producer (corn, green arrows point from it to primary consumers), primary consumers (yellow arrows point from them to secondary consumers), secondary consumers (blue arrows point from them to tertiary consumers), tertiary consumers (red arrows point from them to higher consumers), and decomposers (microorganisms, which break down all dead organisms, so arrows would point from all organisms to them).
2. Correct the food web based on actual feeding relationships:

• Producer: Corn (green arrows to primary consumers: caterpillar, deer, mouse, squirrel)
• Primary consumers (yellow arrows to secondary consumers):
• Caterpillar → Crow
• Deer → Cougar
• Mouse → Snake, Crow
• Squirrel → Snake, Crow
• Secondary consumers (blue arrows to tertiary consumers):
• Crow → Cougar
• Snake → Cougar
• Decomposers: Microorganisms (all dead organisms (snake, corn, caterpillar, deer, crow, mouse, cougar, squirrel) are broken down by them, so arrows point from each organism to microorganisms)

1. Fix arrow colors to match the rules: green (producer to primary consumer), yellow (primary to secondary), blue (secondary to tertiary), and ensure no incorrect cross-feeding arrows (e.g., deer does not eat caterpillar, snake does not eat deer).

Answer:

Corrected Food Web (with proper arrows and colors):

1. Green Arrows (Producer → Primary Consumer):

• Corn → Caterpillar
• Corn → Deer
• Corn → Mouse
• Corn → Squirrel

1. Yellow Arrows (Primary Consumer → Secondary Consumer):

• Caterpillar → Crow
• Deer → Cougar
• Mouse → Snake
• Mouse → Crow
• Squirrel → Snake
• Squirrel → Crow

1. Blue Arrows (Secondary Consumer → Tertiary Consumer):

• Crow → Cougar
• Snake → Cougar

1. Decomposer Connections:

• All organisms (Snake, Corn, Caterpillar, Deer, Crow, Mouse, Cougar, Squirrel) → Microorganisms (decomposers, break down dead matter)
