Trophic Pyramid
Energy is lost at each level of the trophic pyramid. Why, where does it go?
The energy is lost as heat. Producers lose the most energy and tertiary consumers lose the least.
What is primary succession?
After a disturbance there is no soil left.
What is biodiversity?
The amount of different species in an area
What is commensalism? Give an example
+/0, one animal benefits, one has nothing happen. Birds and cows, whales and barnacles, etc.
What are producers? Give 2 examples
Any organism that can do photosynthesis. (Plants like flowers, trees, grass, ...)
What is secondary succession?
After a disturbance there is soil left.
Easy to collapse...
What is parasitism/predation? Give an example
What are secondary consumers? Give 3 examples.
Secondary consumers eat other organisms and are eaten by tertiary consumers. ( Fox, small birds, spiders, ...)
What is a climax community?
A community with high biodiversity that is difficult to disturb and can recover from disturbances easily.
Why is high biodiversity good?
Many different types of species that stabilize ecosystems...
What is competition? Give an example
-/-, when two organisms compete over resources it hurts both of them by taking away energy and focus from more important things. Sheep fighting, bower birds, etc.
What are tertiary consumers? Give 3 examples of organisms
Any organism that can eat other organisms and isn't eaten. (wolf, bear, lion, tiger, human,...)
What is a pioneer community? What are pioneer species?
A pioneer community is the community that exists after a disturbance. Lichens, mosses, and small grasses are examples of pioneer species.
What are 5 things that can hurt biodiversity?
invasive species, pollution, hunting, land development, habitat fragmentation, agriculture, etc.
What is mutualism? Give an example.
+/+, two organisms help each other survive, benefits both. Clownfish/anemone
What is a trophic cascade? Give an example of a trophic cascade that has collapsed and list at least 2 consequences of that collapse.
A trophic cascade is how everything is connected and the organisms at the top and bottom of the pyramid all rely on each other. Too much of one organism is a bad thing and can disturb the ecosystem. Yellowstone national park is one example, because no wolves were there to control deer populations, many other animals left and the park became less biodiverse.
How can you compare the biodiversity of a farm field to the biodiversity of a thick forest?
Farm has low biodiversity, forest has high biodiversity....
What is the most biodiverse place on earth?
Tropical Andes Biodiversity Hotspot
What is the name of the relationship between plants and mushrooms? Is it always mutualistic?
Mycorrhizae, no
