Ecosystems have trouble adjusting to short-term changes. true or false user: climate changes can produce various effects in ecosystems. which of the following is a way that marine ecosystems can be affected by climate warming trends?
a. decreased ocean acidity
b. increased populations of fish
c. decreased levels of carbonate
d. all of the above

1. The answer is False.

A healthy ecosystem can adapt to short-term changes. Many species have adaptive characteristics that help them respond to natural, short-term changes. For example, some plants can regrow from roots that survived in a forest fire. 

2. The answer is C. 

Climate warming is caused by CO₂ trapped in the atmosphere. These trapped carbon dioxide molecules are absorbed by the oceans. The absorption of CO₂ causes chemical reactions in seawater and one of them is it decreases the carbonate ion concentration.
