Question

Claim: The removal of the krill causes a trophic cascade.

Evidence: What data can you use from your food web to support the above claim?
A) The number of predators in the ecosystem
B) The population of krill in the ecosystem
C) The primary producers in the food web
D) The geographical distribution of the ecosystem

Answer 1

In a food web, the removal of krill can cause a trophic cascade that affects the populations at different trophic levels.

Step-by-step explanation:

In a food web, the removal of krill can cause a trophic cascade. A trophic cascade occurs when a change in one trophic level affects the other levels in the food web.

For example, if you remove krill from a food web in the ocean, it can have cascading effects on the populations of predators that rely on krill as their primary food source.

Without krill, the predators may not have enough food to eat, leading to a decrease in their population. This can then impact the next trophic level, as the decrease in predators may cause an increase in the population of the prey of the predators' prey.
