Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily caused by increased levels of carbon dioxide (CO2) and other greenhouse gases in the atmosphere.

Front

What are the effects of water pollution?

Back

Water pollution can lead to harmful effects on aquatic life, including organisms mistaking trash for food, increased algae growth, and the formation of trash islands in oceans.

Front

What is a non-native species?

Back

A non-native species is an organism that is introduced to a new environment where it does not naturally occur, often leading to competition with native species.

Front

What happens to a population when a non-native species out-competes it for resources?

Back

The population of the native species may decrease due to reduced access to essential resources, such as food.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can support sustainably.

Front

How can humans manipulate a population's carrying capacity?

Back

Humans can manipulate carrying capacity by introducing or eliminating predators, changing the availability of resources, or altering the habitat.

Front

What is the impact of introducing a new predator to a population?

Back

Introducing a new predator can decrease the carrying capacity of the prey population by increasing mortality rates.

Front

What is the relationship between CO2 levels and climate change?

Back

Increased levels of CO2 in the atmosphere trap heat, leading to global warming and climate change.

Front

What are some examples of water pollution?

Back

Examples of water pollution include chemical runoff from agriculture, plastic waste in oceans, and sewage discharge.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity contributes to ecosystem resilience, stability, and the ability to recover from disturbances.
