Scientific Method
What is the scientific method?
A systematic, organized process used by scientist to conduct research.
What is Ecology?
Ecology is the study of organisms interacting in their environments.
What is the different between a food web and food chain?
A food chain shows a single path of energy flowing through an ecosystem when a food web shows a complex network of them in an ecosystem.
What are 3 things that are different between reptiles and amphibians?
Amphibians- live on both land and water, moist skin, and have webbed feet
Reptiles- Dry skin, live on land, huff feet
What is an invasive species?
An invasive species is any non-native species that out compete the local species and that are able to adapt to there new environment.
What is a independent variable?
The variable you decide to change?
Explain the energy flow that happens in an ecosystem?
The energy flow that happens in an ecosystem is that energy is loss as the ecological pyramids goes upward.
What is a producer?
An organism that can make it's own food by converting the sun into energy through photosynthesis.
Describe the 3 differences between turtles and tortoises?
Turtles- omnivores, lives primarily in the water, webbed feet
Tortoise- clubbed feet, herbivores, lives only on land
What are two examples of invasive species?
Devil Head
Zebra Mussels
What is a dependent variable?
The one that changes because of the one you decided to change.
What is the structure of an ecological community?
First there are the producers. Then the primary consumer which are herbivores then the secondary consumer which are usually omnivores and then on top is the tertiary consumers which are usually carnivores.
What is a consumer?
An organism that cannot make its own food, must eat other organism to gain energy.
What is the carapace, plastron- and the bridge of a turtle?
The carapace is the upper part the plastron- is the bottom part and the bridge connects the two.
What is biological control?
Biological control is when a new species is introduced to control another one.
What is the control Variable?
The variables which are held constant throughout the entire experiment.
Littoral- shallow shoreline area
Lementic- Open water light penetration
Profundal- Deep water with little or no light
Benthic- The bottom were debris is with no light
What is a decomposer?
An organism that uses enzymes to break down dead organisms.
List three local turtle species?
Red Ear Slider
Eastern Painted Turtle
Common Snapping Turtle
How do invasive species travel?
-Fire wood
- Hiking boots
-Storms
-Climate change
-Pets
What is the different between scientific theory and scientific law?
Scientific law is what happens in nature and scientific theory describes why something happens.
What are some of the ways that humans impact the ponds and lakes?
-Chemical pollution
-Sewage
-Overfishing
-Invasive species
-Solid waste
What is the 10% rule in a energy pyramid?
That only about 10% of the energy from one trophic level is transferred to the next.
What is a Turtles habitat?
They prefer ponds or slow moving rivers with lots of vegetation and muddy bottoms.
What is one negative of biological control?
The that species that you introduced could also become invasive to the area.
