Back

Invasive species can increase in number quickly, leading to less food and resources for native species.

Front

What happens if a key species in a food chain is removed?

Back

If a key species, like herring, dies, all organisms in the food chain would be affected in some way.

Front

What is the first organism in a food chain?

Back

The first organism in a food chain is always a producer, which creates energy through photosynthesis.

Front
