Homeostasis
This is the definition of homeostasis.
What is "to maintain a stable internal environment?"
Producers use this to start the process of photosynthesis.
What is sunlight?
Consumers do this to get glucose for cellular respiration.
What is eat?
This is a lab that demonstrates how diffusion moves across a semipermeable membrane, while also demonstrating urchins in acidic waters.
What is the egg lab?
This is an extinction event that took out 95% of all life on Earth.
What is The Great Dying?
This is the body's reaction when homeostasis is disrupted due to a fever and the brain's set point for body temperature has changed.
What is shivering?
This is a metabolic process that creates glucose and oxygen.
What is photosynthesis?
This metabolic process has carbon dioxide as a waste product.
What is cellular respiration?
Diffusion is molecules moving in what manner?
This is the level at which a population reaches homeostasis.
What is carrying capacity?
This is a species responsible for the homeostasis of their ecosystem.
What is a keystone species?
Producers do this to create energy.
What is cellular respiration?
This is a waste product of cellular respiration.
What is carbon dioxide?
This is an action that is an example of how diffusion maintains homeostasis in the lungs.
What is breathing?
This is a natural predator of sea otters.
What are sharks?
This homeostatic mechanism is activated by the trigeminal nerve.
What is the mammalian dive response?
This is a waste product of photosynthesis, though it can be used by certain organelles.
What is oxygen?
In consumers, this is where carbon dioxide first goes to after the process of cellular respiration.
What is the blood stream?
This is a special membrane in which certain particles can freely move across.
What is a semipermeable membrane?
This is the study of owls.
What is strigiformology?
Dr. Payne discovered the top-down theory and keystone species by throwing starfish out of tide pools. His research helped save this species from extinction.
What are sea otters?
Root cells require nutrient flow from these tubes in order to create energy.
What are xylem and phloem?
Consumers cannot use photosynthesis. They do these two things to compensate for the important molecules they need to create energy.
This is a seasonal example of how diffusion of nitrogen affects aquatic life.
What is the Gulf of Mexico Dead Zone?
This is an ecological phenomenon where changes to the population of a top predator ripple down through multiple levels of a food web, dramatically affecting all other organisms like herbivores and even plants/primary producers
What is a trophic cascade?
