Trophic Levels
Give an example of an autotroph.
What is a plant/producer?
Draw a simple food chain where an owl is the secondary consumer.
plant --> rodent --> owl
Name the 5 types of relationships we studied in this class.
What is mutualism, commensalism, parasitism, competition, predation
How do producers obtain energy?
What is sunlight/photosynthesis?
What are the 6 main elements found in all biotic factors?
CHNOPS
Give an example of a primary consumer and explain where it gets it's energy.
What is an organism that eats producers.
What are 2 other terms for "primary consumer"
What is "vegetarian" and "herbivore"?
Tapeworms are sometimes found in the small intestines of sheep. A tapeworm attaches to the intestinal wall using suckers and then absorbs nutrients from the sheep’s intestine. What is the relationship between the tapeworm and the sheep?
What is parasitism?
How much energy is transferred when you move up one trophic level? (answer in percentage)
What is 10%?
The arrows in a food web always point in this direction.
What is toward the eater/direction of energy flow.
Give an example of a secondary consumer and explain where it gets it's energy.
What is an organism that eats primary consumers.
Provide an example of a heterotroph and explain why.
An organism that eats other organisms for energy.
What is the difference between mutualism and commensalism?
What is mutualism= both benefit, commensalism = 1 benefits, 1 unharmed/no benefit
What is an owl pellet?
What is fur, feathers, and bones regurgitated by an owl.
Provide an example of a biotic factor and an abiotic factor at Yellowstone National Park.
Biotic: Elk, wolf, grass
Abiotic: River, dirt, water
Give an example of a tertiary consumer and explain where it gets it's energy.
What is an organism that eats secondary consumers.
Which trophic level receives more energy, producers or apex predators?
What is "producers"?
What is the difference between "competition" and "predation"?
Competition= two organisms going after same resource Predation= one organism hunting another organism
Why do owls make pellets?
What is the remains of their prey cannot be digested and much be thrown up to make more room in their stomachs.
Provide an example of a decomposer. Explain.
What is an organism that eats dead organisms.
What happens to CHNOPS in a dead organism after a decomposer breaks it down?
CHNOPS returns to the earth for producers to use.
What does "trophic level" mean?
It refers to the energy level of an organism.
Ticks carry bacteria that cause Lyme disease. Ticks do not get Lyme disease, but they can transfer the bacteria to humans, who can get the disease. What is the relationship between bacteria and ticks? Ticks and the humans?
What is "The relationship between the bacteria and the ticks is commensalism, and the relationship between the ticks and the humans is parasitism."
Tiger beetles chase small spiders, which they catch in their strong jaws and then eat. What is the ecological relationship between tiger beetles and spiders?
What is PREDATION?
The loss of the producers in an ecosystem would most likely result in which of the following changes?
What is "a decrease in the primary consumers and the secondary consumers"
