What is an invasive species?

• An organism that is new to an environment that has positive effects on the environment.

• An organism that is new to an environment that has negative effects on the environment.

• An organism that is native to an environment that has positive effects on the environment.

Introduced species can become pests because they;

• Produce only a few young after a long period of gestation.

• Inhabit only niches that have recently become available after the local extinction of another species.

• Can live in many niches, easily adapting to many variables and eating a wide variety of food.

• Have a low genetic variability, enabling them to live in a wide variety of habitats.

• Increase biodiversity because they attract more species to the areas in which they settle.

Which of the following are ways that an invasive species may enter an aquatic ecosystem?

I. Releasing the ballast water of ships.

II. Dumping household aquariums into lakes.

III. Escaping a coastal aquaculture farm.

• I only.

• II only.

• III only.

• I and II only.

• I,II, and III.

Presently, the biggest threat to biodiversity is;

• Asteriod strikes, such as what happened 65 million years ago and resulted in the extinction of the dinosaurs.

• Human population growth, because as population increases, so does the number of plants and animals it consumes, resulting in a decrease of those organisms.

• Habitat destruction, such as cutting down portions of tropical rain forest, which destroys the niches occupied by tropical organisms.

• The proliferation of zoos and botanical gardens, causing causing people to care less about preserving species in the wild because they are being cared for those in sanctuaries.

• Climate change, because it will result in many species moving northward or to higher elevations, seeking out suitable new habitats.
