The 4 Pillars of Diversity
100

This level of biodiversity refers to the variety of genes within a single species, such as the different breeds of dogs.

What is Genetic Diversity?

100

This is the specific physical place where an organism lives.

What is a habitat?

100

In this type of relationship, one organism feeds off another, requiring a careful balance so neither population goes out of control.

What is a Predator/Prey relationship?

100

This is the term for unknown species introduced by humans that can accidentally ruin the balance of an ecosystem.

What are Invasive Species?

100

This pillar states that a diverse ecosystem leads to many different niches, allowing organisms to use up all the different resources available.

What is Efficiency?

200

This is the variety of habitats available in a given area, which is often confused with a specific organism's "home."

What is Ecosystem Diversity?

200

This term describes an organism's specific "job" or role in its ecosystem, including what it eats and how it interacts with the environment.

What is an ecological niche?

200

This is the relationship where both species benefit, such as bees collecting nectar from flowers

What is mutualism?

200

This is the ability of an ecosystem to maintain its balance or completely recover after facing a major disturbance.


What is Ecosystem Stability?

200

This pillar explains that if one species fails or goes extinct, another species can take its place so the food chain doesn't collapse.

What is Reliability?

300

This level of biodiversity measures both the total number of different species in an area and how balanced their populations are.

What is Species Diversity?

300

For a species to adapt to ecosystem changes, it needs this type of variety so at least a few individuals possess traits that help them survive.

What is Genetic Variety?

300

This occurs when two or more species fight over the exact same limited resources in an ecosystem.

What is competition?

300

Human overharvesting causes harm to plants, while this specific human factor causes the overuse of environmental resources due to more people existing.

What is Population Growth?

300

Predator/prey relations and competition represent this pillar, which prevents any single species from completely overrunning a habitat.

What is Balance?
