Question

part 1: food webs & ecological pyramids
task a. using the organism grass, rabbit, hawk, snake, grasshopper, frog, mushroom, and bacteria, draw a food web showing energy flow with arrows pointing from the food source to the eater, including all possible feeding connections.

Explanation:

Step1: Identify producers

Grass is a producer which is the base of the food - web as it can make its own food through photosynthesis.

Step2: Identify primary consumers

Grasshopper and rabbit eat grass. So, arrows will point from grass to grasshopper and from grass to rabbit.

Step3: Identify secondary consumers

Frog eats grasshopper, snake eats rabbit and frog. So, arrows point from grasshopper to frog, from rabbit to snake and from frog to snake.

Step4: Identify tertiary consumer

Hawk eats snake. So, an arrow points from snake to hawk.

Step5: Identify decomposers

Mushroom and bacteria are decomposers. They break down dead organisms (grass, rabbit, hawk, snake, grasshopper, frog). So, arrows point from all these organisms to mushroom and bacteria.

Answer:

A food - web with arrows pointing from grass to grasshopper, grass to rabbit, grasshopper to frog, rabbit to snake, frog to snake, snake to hawk, and from grass, rabbit, hawk, snake, grasshopper, frog to both mushroom and bacteria.
