What is a primary consumer?

Back

A primary consumer is an organism that eats producers, such as plants. In the food chain, it is the second trophic level.

Front

Why do invasive species thrive in new environments?

Back

Invasive species have no natural predators in the new environment, allowing their populations to grow rapidly.

Front

How does deforestation affect carbon dioxide levels?

Back

Deforestation reduces the Earth's capacity to absorb carbon dioxide, leading to increased levels of carbon dioxide in the atmosphere.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

What is an example of a top predator?

Back

An example of a top predator is a wolf, which has no natural enemies in its ecosystem.

Front

What is eutrophication?

Back

Eutrophication is the process by which water bodies become overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.

Front

What is the impact of invasive species on native ecosystems?

Back

Invasive species can outcompete native species for resources, disrupt food webs, and lead to declines in biodiversity.

Front

What is mass extinction?

Back

Mass extinction is a significant and rapid decrease in the biodiversity on Earth, often caused by catastrophic events or human activities.
