Biodiversity
This level of organization is defined by organisms that can interbreed and produce fertile offspring.
What is a species?
This type of organism creates its own food, often through photosynthesis.
What is a producer/autotroph?
This interaction occurs when two or more species compete for limited resources.
What is competition?
This type of niche includes competition, predation, and other interactions in the real world.
What is a realized niche?
This term refers to a distinct boundary in rock strata that marks differences in geologic eras.
What is an epoch?
This term describes the specific role an organism plays in its community, such as controlling fish populations in a pond.
What is a niche?
These organisms eat both plants and animals.
What is an omnivore?
This type of relationship benefits one organism while the other is unaffected.
What is commensalism?
Species that are not native to an ecosystem and compete with native species for resources are called this.
What is an invasive species?
This large-scale destruction of forests for farming, industry, and development leads to habitat loss and species extinction.
What is deforestation?
This level combines living organisms with non-living factors like temperature and water.
What is an ecosystem?
This simplified model starts with a producer and ends with a top consumer, showing one possible energy path.
What is a food chain?
In this relationship, both organisms benefit from the interaction.
What is mutualism?
This type of species plays a critical role in maintaining the structure of an ecosystem and cannot be easily replaced. (wolves of Yellowstone)
What is a keystone species?
The growth and expansion of cities that causes habitat fragmentation and forces species to relocate.
What is urbanization?
This biome features warm temperatures year-round, high biodiversity, and dense vegetation.
What is the tropical rainforest?
This specifically shows the flow of energy in a food web or food chain.
What is an arrow?
This interaction occurs when one organism hunts and kills another for food.
What is predation?
This term refers to how much environmental change an organism can handle while still surviving and reproducing.
What is range of tolerance?
Known as the “Human Epoch,” this current geological epoch is defined by human activities like industrialization and globalization.
What is the anthropocene?
This term refers to large terrestrial areas defined by common climate, vegetation, and animal life.
What is a biome?
This system of interlocking food chains shows all possible paths for energy to travel in an ecosystem.
What is a food web?
According to this principle, no two species can occupy the same niche in the same habitat at the same time and both survive.
This process involves organisms changing to become better suited to their environment, often shaping their niche.
What is adaptation?
This process introduces non-native species into ecosystems, often through exotic pets or global travel, disrupting native species.
What is the introduction of invasive species?
