What would most likely happen if the kangaroo rats were killed off and removed from the food chain?

The number of snakes would increase.

The number of cactus plants would increase.

The number of foxes would be unaffected.

The number of cactus plants would be unaffected.

The number of cactus plants would increase.

Explanation:

If an animal is removed from the food chain, its effect on the entire food chain. Similarly, if the kangaroo rat is removed from the food chain, then the cactus plant will grow immensely but there will be a possibility of a shortage of animals that eat the kangaroo rat.

The main diet of kangaroo rat is the cactus plant, so when the kangaroo rat is extinct from the food chain, the cactus plant will grow at a fast pace in the Food Chain.

b. The number of cactus plants would increase.

Explanation:

Food chain is defined as a linear netwrok between producer and high level predators of environment and shows the flow of energy between them.

Kangaroo rats are rodents which lives in desert and feed over cactus plants, grass and other isects for their survival. If kangaroo rats will be removed from the food chain, the number of cactus plants will increase as kangaroo rats will not be there to feed them and number of snakes will decrease as snakes may die as they feed over kangaroo rats.

Hence, the correct option is b.
