Spotlight on Species
This term refers to the variety of life at all levels of biological organization, from genes to ecosystems.
What is biodiversity?
This element is critical for plant growth and is cycled through ecosystems, often disrupted by human activities like farming and pollution.
What is nitrogen?
This theory explains why individuals with certain traits survive and reproduce.
What is Darwin's Theory of Natural Selection?
These are the three layers of the Earth.
What are the crust, mantle, and core?
This refers to the inherent worth of something, independent of its usefulness or external factors.
What is intrinsic value?
This refers to the phenomenon where a species no longer exists anywhere on Earth.
What is extinction?
This is the topmost layer of soil that consists primarily of organic matter, such as decomposed leaves, plants, and animal material.
What is the O Horizon?
This is the measure of the relative viability and fertility of an organism.
What is fitness?
This mountain range stretches from New England to Georgia.
What are the Appalachian Mountains?
This refers to the number of births per 1,000 people per year.
What is the Crude Birth Rate?
This is the process by which rocks and minerals are broken down into smaller particles or altered through physical, chemical, or biological means.
What is weathering?
Approximately 30,000 different kinds of these building blocks combine to form a unique individual.
What is a drought?
This is a process that occurs in an area where no previous ecosystem existed, beginning in lifeless environments where there is no soil, followed by the gradual establishment of biological communities over time.
What is primary succession?
This is the minimum number of species that a rainforest contains.
What is 10 million?
This is a method of catching fish and other marine organisms using specially designed containers or enclosures that attract and capture aquatic species. This technique is an environmentally friendly method of capturing marine life.
What is Pots and Traps Fishing?
This is a type of genetic drift that causes a population to decrease drastically due to hunting and habitat loss.
What is the bottleneck effect?
What is restorative ecology?
These are the three cycles that are considered the building blocks of life.
What are the hydrologic cycle, the carbon cycle, and the nitrogen cycle?
Researchers measure this environmental indicator in terms of the number of mammal species per 10,000 species per 100 years.
This cycle does not have an atmospheric component.
What is the Phosphorus Cycle?
This is a type of relationship between two species where both take each other's resources for their own benefit.
What is reciprocal exploitation?
This biome is also referred to as prairies in the US and steppes in central Asia.
What is a grassland?
These are toxic chemicals created by humans for industrial purposes that can accumulate in both the environment and in organisms.
That are Persistent Organic Pollutants?
