Question 1 of 3
In a meadow food web, the following feeding relationships are known: - Grass is eaten by rabbit and grasshopper. - Grasshopper is eaten by frog. - Frog is eaten by snake. - Snake is eaten by hawk. - Rabbit is eaten by fox. - Fox is eaten by hawk. - Mushroom decomposes dead beetle and dead leaf. Which of the following is a correct food chain that could occur in this meadow?
Question 2 of 3
The food web shows organisms in a meadow ecosystem. How many decomposers are in this food web?
A Meadow food web with 6 labeled organisms: Grass (producer), Clover (producer), Rabbit (primary), Mouse (primary), Fox (secondary), Mushroom (decomposer). Arrows show matter movement from prey to predator.
Question 3 of 3
The food web shows organisms in a desert ecosystem. How many decomposers are in this food web?
A Desert food web with 7 labeled organisms: Cactus (producer), Sage (producer), Mouse (primary), Lizard (primary), Rabbit (primary), Snake (secondary), Beetle (decomposer). Arrows show matter movement from prey to predator.
