Question

1. predict which characteristics would most likely be observed in an ecosystem that experiences a moderate level of disturbance? select all correct answers.

a. nutrient - poor soil
b. lack of mature species
c. mostly colonizer species
d. relatively high species diversity
e. mix of colonizer and mature species

Explanation:

According to the intermediate disturbance hypothesis, moderate - level disturbances create a balance. Nutrient - poor soil (A) is not a general characteristic of such ecosystems. A lack of mature species (B) and mostly colonizer species (C) are more likely in highly disturbed ecosystems. When there is a moderate disturbance, it prevents the dominance of a few mature species (which would out - compete others in a less - disturbed environment) and also allows some mature species to persist (unlike in highly disturbed environments where only colonizers can survive). This leads to a relatively high species diversity (D) as different species have opportunities to co - exist, and there is a mix of colonizer and mature species (E).

Answer:

D. relatively high species diversity, E. mix of colonizer and mature species
