Hydrilla is an invasive aquatic plant with an extremely high growth rate. It can grow up to 2.5 cm per day. Hydrilla has the same access to resources needed to carry out photosynthesis as native plants such as pondweed.
These autotrophs compete for this limited resource.

The flying carp is a foreign fish that has been introduced by humans into American rivers. These fish feed on native fish populations and some of the same food sources as many native fish populations.
This is one relationship that exists between the flying carp and the native fish population.

Biofuels are a promising renewable energy source and climate-smart alternative to fossil fuels. However, biofuels can negatively impact the environment and biodiversity , due to land-use changes such as deforestation and the use of fertilizers and pesticides. This comprise is considered a _____________________.
