nutrient cycling
b
food production
c
soil creation
d
water cycling
Question 20 (1 point)
What is the definition of ecological resistance?
a
an ecosystem’s ability to endure in changing conditions
b
an ecosystem’s ability to manage population density
c
an ecosystem’s ability to improve after a setback
d
an ecosystem’s ability to replace species that are wiped out
Answer 19: The ecosystem service that decomposers provide is nutrient cycling.
Answer 20: The definition of ecological resistance is an ecosystem's ability to endure in changing conditions.
Question 19:
Decomposers provide the ecosystem service of nutrient cycling (option a).
Question 20:
The definition of ecological resistance is an ecosystem's ability to endure in changing conditions (option a).
To find the answer to question 19, we need to understand what decomposers are and what ecosystem services are. Decomposers are organisms like bacteria, fungi, and worms that break down dead organic matter and recycle nutrients back into the ecosystem. Ecosystem services are the benefits that ecosystems provide to humans.
Looking at the provided options, we can see that option "a" is the correct answer, as nutrient cycling is a key ecosystem service provided by decomposers. Nutrient cycling refers to the process of breaking down and recycling nutrients from dead organisms back into the ecosystem, making them available for other organisms to use.
To find the answer to question 20, we need to understand what ecological resistance is. Ecological resistance refers to an ecosystem's ability to endure or withstand disturbances or changes without undergoing significant changes in structure or function.
Looking at the provided options, we can see that option "a" is the correct answer, as an ecosystem's ability to endure in changing conditions defines ecological resistance. This means that an ecosystem can maintain its structure and function even when faced with environmental changes or disturbances.
