• An increase in the number of foxes eating the cacti in the area.

• A decrease in the number of foxes eating the cacti in the area.

• An increase in the amount of rain.

• All of the above will impact the carrying capacity of the cactus population

Forest A consists of only Oak trees and Forest B has Oak trees, Maple trees, and some pine trees.

Which of the following is true?

• Forest B has more biodiversity than Forest A.

• Forest A has more biodiversity than Forest B.

• Neither forest is more biodiverse

• Both forests are equally biodiverse.

What is biodiversity?

• the variety of life in an ecosystem

• how life changes over time in an ecosystem

• the exact number of species in an ecosystem

• the feeding job of an organism.

What is the difference between a food chain and a food web?

• Food chains begin with a producer and are a linear progression of energy flow.

• Food webs begin with a producer and are a linear progression of energy flow.

• Food chains are a network of producers and consumers.

• Food webs only show one producer and multiple consumers.

What is a niche?

• The feeding job of an organism; it's role in the ecosystem.

• Something you eat.

• A trophic level in a food chain.

• One food chain in a food web.
