Question

Select the correct answer. If the population of rabbits in this ecosystem decreased dramatically because of certain environmental changes, which organisms’ food supply would decrease? Illustration of food web in ecosystem depicts predators which are Lion, Jackal, Goat, Rabbit, Mouse, Wild Cat, Owl, Snake, Kite. Prey animals are Jackal, Goat, Rabbit, Mouse, Snake, Wild Cat. Green Plant is eaten by Goat, Rabbit and Mouse. A. owl and snake B. jackal and wildcat C. green plant and mouse D. goat and wildcat

Answer 1

Based on the food web described, if the population of rabbits in this ecosystem decreased dramatically due to environmental changes, the organisms' food supply that would decrease are the ones directly dependent on rabbits as a prey source.

From the given options, the correct answer would be option B: jackal and wildcat. This is because both the jackal and wildcat are predators that rely on rabbits as a food source. With a decrease in the rabbit population, the food supply for the jackal and wildcat would be greatly affected.

Option A (owl and snake) is not correct because although owls and snakes are predators in the ecosystem, they do not primarily depend on rabbits as their main food source. They have a broader diet that includes other prey animals.

Option C (green plant and mouse) is also not correct because the green plant is not directly affected by the decrease in the rabbit population, and mice are not specifically dependent on rabbits as their main food source.

Option D (goat and wildcat) is not correct because while wildcats are indeed dependent on rabbits, goats are not directly reliant on rabbits as their primary food source.

Remember, when analyzing a food web, it's important to consider the specific interactions and dependencies between organisms to determine which ones would be impacted by changes in population sizes.
