Planet Earth and Beyond
These types of factors include living organisms like plants, animals, and bacteria.
What are biotic factors?
In a food web, this type of organism is at the top and has no natural predators.
What are apex predators (tertiary consumers)?
This type of limiting factor increases in effect as population density increases.
What are density-dependent limiting factors?
This type of symbiosis benefits both organisms involved.
What is mutualism?
This is one piece of evidence that supports the claim that Earth’s climate is changing.
What are rising global temperatures?
This term refers to the long-term average of temperature and precipitation in a region.
What is climate?
This term describes organisms that obtain energy by consuming other organisms.
What are consumers (heterotrophs)?
This type of population distrobution has organisms spread out evenly away from one another.
What is uniform distrobution?
This zone lies between the optimal range and the zone of intolerance.
What is the zone of physiological stress?
This is the definition of biodiversity.
What is the variety of life in an area, including species, genetic, and ecosystem diversity?
This biome is known for its high biodiversity and year-round warm temperatures.
What is a rainforest?
This nutrient cycle involves bacteria that convert nitrogen gas from the atmosphere into forms usable by plants.
What is the nitrogen cycle?
Carrying capacity describes this.
What is the maximum number of individuals an environment can sustainably support?
This type of succession occurs in areas where a disturbance has left soil intact.
What is secondary succession?
This gas is the main concern for climate change.
What is carbon dioxide?
This level of organization encompasses multiple ecosystems with similar climates and organisms.
What are biomes?
Energy pyramids always narrow toward the top due to this reason.
What is because energy is lost as heat at each trophic level?
On a logistic growth graph, this is the shape of the graph.
What is an s-shape?
This is the reason microhabitats are important for biodiversity.
What is they provide specialized niches that support different organisms?
These are the five types of alternative energy sources humans use in place of fossil fuels.
What are wind power, hydroelectric power, solar power, nuclear fission, and biomass burning?
This is the reason the Southern Hemisphere experience summer while the Northern Hemisphere experiences winter?
What is the tilt of the Earth's axis?
Decomposers play a crucial role in nutrient cycles by doing this.
What is recycling nutrients back into the environment?
Read this short paragraph....
Mr. Dorsey wants to know how many kangaroos live in Australia. He sets out a trap for a week and captures 20 kangaroos and marks them. A week later he sets out a new trap. He comes back after a week and finds 30 kangaroos, 15 are marked.
This number describes how many kangaroos are in Australia.
What is 40 kangaroos?
This is the reason keystone species crucial for maintaining biodiversity.
What is they help regulate populations and maintain the structure of the ecosystem?
This is one way invasive species can negatively impact native organisms.
What is by outcompeting them?
