Question

question 2 of 10
why can the removal of one important species affect an entire ecosystem?
a. most ecosystems have unlimited shelter and food.
b. organisms in an ecosystem do not compete for resources.
c. all the organisms in an ecosystem interact with each other.
d. most ecosystems only have one producer.

Explanation:

In an ecosystem, organisms interact. If a key species is removed, it disrupts these interactions. For example, if a main producer (like a dominant plant) is gone, herbivores that depend on it lack food. This then affects carnivores that eat those herbivores. Ecosystems don't have unlimited shelter/food (A is wrong), organisms do compete for resources (B and C are wrong). So the interaction of organisms (as in D) explains why removing one important species affects the whole ecosystem.

Answer:

D. Most ecosystems only have one producer
