Fisherman in a certain region have noticed a significant decrease in the biodiversity of fish species present in a local body of water. This has caused a decrease in the variety of fish available for consumers in the region. Which of the following changes has most likely caused this change in biodiversity? A.

an increase in fish reproduction rates

B.

the introduction of an invasive species

C.

a decrease in water pollution

D.

a prolonged period of increased rainfall

B

Explanation:

The introduction of an invasive species makes sense, because invasive species can wipe out mulitple native species leaving less resources for the native fish, and thus, decreasing biodiversity. A great real life example of this would be the Lionfish.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
