To solve this problem, we need to place each animal and plant into the correct level of the energy pyramid based on what they eat.
Step 1: Identify the Producers (Bottom Level)
Producers are plants that get their energy from the sun. They do not eat other organisms.
* Looking at the pictures,
Grass and
Cattail are plants.
* These go in the bottom section labeled "Producers."
Step 2: Identify the Primary Consumers (Second Level from Bottom)
Primary consumers are herbivores. This means they only eat plants.
*
Grasshopper: Eats grass.
*
Cricket: Eats plants like grass and cattails.
*
Shrew: While shrews often eat insects, in many simple food chains for students, they are sometimes grouped here if they eat seeds, but let's look closer. Actually, shrews are mostly insectivores/carnivores. Let's look at the other animals first.
* Wait, let's re-evaluate the
Shrew. Shrews primarily eat insects (like crickets and grasshoppers) and small invertebrates. This makes them secondary consumers.
* Let's check the
Mouse/Rat image labeled "Shrew". In some contexts, if it were a field mouse, it would be a primary consumer. However, the label says "Shrew". Shrews are carnivores/insectivores. Let's hold on this and look at the others.
* Let's look at the
Grasshopper and
Cricket again. They definitely eat plants. So they are Primary Consumers.
Step 3: Identify the Secondary Consumers (Third Level from Bottom)
Secondary consumers eat primary consumers (herbivores). They can be omnivores or carnivores.
*
Frog: Frogs eat insects like crickets and grasshoppers. Since crickets and grasshoppers are primary consumers, the frog is a secondary consumer.
*
Shrew: As noted, shrews eat insects (crickets/grasshoppers). Therefore, the shrew is also a secondary consumer because it eats primary consumers.
Step 4: Identify the Tertiary Consumers (Fourth Level from Bottom)
Tertiary consumers eat secondary consumers. They are usually carnivores.
*
Snake: Snakes often eat frogs and shrews. Since frogs and shrews are secondary consumers, the snake is a tertiary consumer.
Step 5: Identify the Top Predators (Top Level)
Top predators eat tertiary consumers. They are at the very top of the food chain.
*
Hawk: Hawks eat snakes. Since the snake is a tertiary consumer, the hawk is the top predator.
Let's double-check the levels:
1.
Producers: Grass, Cattail
2.
Primary Consumers (eat producers): Grasshopper, Cricket
3.
Secondary Consumers (eat primary consumers): Frog (eats cricket/grasshopper), Shrew (eats cricket/grasshopper)
4.
Tertiary Consumers (eat secondary consumers): Snake (eats frog/shrew)
5.
Top Predators (eat tertiary consumers): Hawk (eats snake)
This fits perfectly into the 5-level pyramid shown in the diagram.
Final Placement:
*
Top Predators: Hawk
*
Tertiary Consumers: Snake
*
Secondary Consumers: Frog, Shrew
*
Primary Consumers: Grasshopper, Cricket
*
Producers: Grass, Cattail
Final Answer:
Producers: Grass, Cattail
Primary Consumers: Grasshopper, Cricket
Secondary Consumers: Frog, Shrew
Tertiary Consumers: Snake
Top Predators: Hawk
