This level includes all the living and nonliving things interacting in an area.
What is an ecosystem?
This type of growth occurs when resources are unlimited, producing a J-shaped curve.
What is exponential growth?
Organisms that make their own food through photosynthesis.
What are producers?
Living components of an ecosystem are called this.
What are biotic factors?
This biome is characterized by very low rainfall and extreme temperatures.
What is a desert?
A group of organisms of the same species living in one area.
What is a population?
This type of growth slows as resources become limited and forms an S-shaped curve.
What is logistic growth?
A linear sequence showing how energy flows from one organism to another.
What is a food chain?
Temperature, sunlight, and water are examples of these.
What are abiotic factors?
This biome has cold temperatures, permafrost, and short growing seasons.
What is the tundra?
Multiple populations of different species living together form this level.
What is a community?
This type of symbiosis benefits one organism while harming the other.
What is parasitism?
Organisms that eat producers are called this.
What are primary consumers?
A cactus in the desert is an example of this type of factor.
What is a biotic factor?
The biome with the greatest biodiversity, found near the equator.
What is the tropical rainforest?
The level of organization defined by climate, vegetation, and wildlife.
What is a biome?
When two species compete for the same limited resource, this interaction occurs.
What is competition?
This diagram shows multiple interconnected feeding relationships.
What is a food web?
This nonliving factor can limit plant growth in a forest.
What is sunlight? (accept water, soil nutrients)
This biome is dominated by grasses and experiences seasonal rainfall.
What is a grassland? (savanna accepted)
This is the smallest level of organization that can carry out all life processes.
What is a cell?
This interaction involves one organism hunting and killing another for food.
What is predation?
Only about this percentage of energy transfers to the next trophic level.
What is 10%?
The interaction between living and nonliving components helps define this.
What is an ecosystem?
This biome has four seasons and trees that lose their leaves in the fall.
What is the temperate deciduous forest?
