The ecological inquiry method an ecologist uses when he or she sets up a greenhouse and measures the effects of different levels of carbon dioxide on an endangered plant
What is experimenting
100
What is the term for each step in the transfer of energy and matter within a food web?
What is trophic level
100
Primary succession would most likely occur after
What is lava flow

Which biomes have the least precipitation? Name 2
What is tundra and desert

Give three examples of resources that a plant would need in its niche in order to live.
What is Answers should include at least three of the following: water, light, nutrients, and space to grow
200
The algae at the beginning of the food chain are
What is primary producers.
200
Why can’t the producers in some ecosystems make an unlimited supply of organic material?
What is One or more nutrients are in short supply.
200
Something that controls the growth or size of a population is
What is a limiting factor.
200
What is one way a freshwater wetland differs from a lake or pond?
What is Water does not always cover a wetland as it does a lake or pond.
200
How is a population with a clumped distribution different from a population with a uniform distribution?
What is In a population with uniform distribution, individuals are all found at relatively equal distances from each other. In a clumped distribution, individuals form tight, distinct groups.
300
Compared to land, the open oceans have what kind of nutrients available.
What is are nutrient-poor environments.
300
During a long period when there is no rainfall, a mountain lion may temporarily leave its usual hunting territory to drink from a farm pond. This behavior is due to?
What is the change in an abiotic factor in its environment.
300
When farming, overgrazing, climate change, and/or seasonal drought change farmland into land that cannot support plant life, it is called?
What is desertification.
300
What events typically contribute to an algal bloom in a lake or ocean?
What is A large input of a limiting nutrient, such as nitrogen or phosphorus, can cause the algae to grow and reproduce more quickly.
300
How can farmers reduce soil erosion on their farms?
What is Farmers can use sustainable farming practices such as crop rotation, contour plowing, and leaving roots and stems in the soil between plantings to reduce soil erosion.
400
How does industrial growth affect the biosphere?
What is Industrial growth results in increased burning of fossil fuels and increased production of waste and pollution.
400
A symbiotic relationship in which both species benefit is
What is mutualism.
400
Compare and contrast photosynthetic producers with chemosynthetic producers.
What is The two producers are alike because they both produce carbohydrates and oxygen and are essential to the flow of energy through the biosphere. They are different because they get their energy from different sources.
400
The human population experienced exponential growth just after
What is the Industrial Revolution began.
400
Contrast biodiversity with species diversity.
What is Biodiversity is the total genetically based variety of all organisms in the biosphere. Species diversity refers to the number of species in the biosphere.
500
Compare exponential growth of organisms that reproduce rapidly with exponential growth of organisms that reproduce slowly.
What is Exponential growth of both organisms will both produce a J-shaped curve on a graph because each generation of offspring will be larger than the generation before. However, the organisms that reproduce slowly will take longer to show as much growth.
500
Why are decomposers the final consumers in every food chain?
What is What is In time, all living things die regardless of where they are in the food chain. The decomposers break down the remains of dead plants and animals, releasing substances that are reused by other organisms in the ecosystem.
500
Compare the movement of energy in the biosphere with the movement of matter through the biosphere.
What is Energy flows in one direction from the sun to producers and consumers. Matter moves in biogeochemical cycles through living systems, Earth, the atmosphere, and the oceans.
500
In nature, it is difficult to observe the effects density-independent limiting factors on real populations because density-independent limiting factors
What is often have a greater effect on denser populations.
500
Name at least three characteristics of sustainable development.
What is Student answers should include at least three of the following: Sustainable development does no long-term harm to soil, water, or climate. Sustainable development consumes as little energy and material as possible. Sustainable development is flexible enough to survive environmental stresses. Sustainable development takes human economic systems and ecosystem goods and services into account. Sustainable development helps people improve their situation.
