This is the protection and careful management of natural resources.
What is conservation?
The variety of life forms in an area is known as this.
What is a biodiversity?
This term refers to anything that restricts population growth, such as food or water.
What is a limiting factor?
This human activity contributes most to deforestation.
What is agriculture (or farming)?
This is the seasonal movement of animals from one place to another.
What is migration?
Reforestation helps conservation by rebuilding this precarious ecosystem.
What is a forest?
Coral reefs are often called this because of their high biodiversity.
What are the "rain forests of the sea"?
Predation, competition, and disease are examples of these types of limiting factors.
What are density-dependent factors?
The release of carbon dioxide from burning fossil fuels contributes to this global issue.
What is climate change / global warming?
Monarch butterflies migrate to this country each winter.
What is Mexico?
This type of reserve is created to protect endangered species in their natural habitat.
What is wildlife sanctuary?
The Amazon rainforest is an example of this type of biome with incredibly high species richness.

What is the Earth's surface?
The maximum number of individuals a habitat can support is called this.
What is carrying capacity?
Species introduced to new habitats that disrupt ecosystems are called this.
What are invasive species?
Birds use these natural cues, such as stars or Earth’s magnetic field, to navigate migration.
What are navigation cues (like magnetic fields, stars, or the sun)?
Protecting keystone species is important because they have this kind of impact on ecosystems.
What is a disproportionate impact?
Loss of biodiversity can disrupt this network of producer-consumer relationships.
What is a food web?
When a population exceeds its carrying capacity, it experiences this effect.
What is an overshoot (leading to population crash)?
Overharvesting fish can lead to collapse of this type of marine resource.
What is a fishery?
This type of migration occurs when humans move from rural areas into cities.
What is urban migration (or urbanization)?
