WorksheetsEverglades Trophic Levels & Food Pyramids
Total questions: 10
Worksheet time: 5mins
What is the primary reason the Everglades is dominated by plants?
The presence of alligators discourages other large animals
Because plants are the primary producers in the ecosystem
Due to the large number of herbivores
Because of the high humidity and rainfall
What is the first trophic level in a food pyramid?
Tertiary consumers
Producers
Secondary consumers
Primary consumers
Which type of organism belongs to the second trophic level?
Primary Consumers: herbivores
Apex Consumers
Small Carnivores
Predators
What rule explains why there can't be too many links in a food chain?
The 50% Rule
The 10% Rule
The Energy Conservation Rule
The Biomass Distribution Rule
Why is a food pyramid shaped the way it is?
It's purely a symbolic representation
Because of the decreasing number of organisms at each trophic level
To represent the hierarchical structure of ecosystems
Due to the increasing amount of energy at each level
What organisms are considered the foundation of the food pyramid discussed?
Producers
Top predators
Herbivores
Decomposers
Which of the following is NOT a reason much of the energy consumed by an organism does not pass to the next trophic level?
It is excreted as waste
It is stored indefinitely within the organism
It is used in digestion and metabolic processes
It passes out into the environment as heat energy
What makes the top predators, such as the American alligator, so special in the food pyramid?
They are the most numerous
They have no natural enemies
They require a large biomass at the bottom to support them
They are the primary producers
Why are decomposers considered important in the ecosystem?
They consume the most energy
They prey on top predators
They convert dead material back into soil
They are the largest animals in the ecosystem
What is the role of periphyton in the Everglades ecosystem?
It is a top predator
It is a secondary consumer
It is a primary consumer
It is a producer
