Sometimes ecosystems change. These changes can be natural or human caused. Some ecosystems can recover from a disturbance and some ecosystems cannot. Which of these ecosystems would be most likely to recover?
|
|
a temperate forest with average biodiversity that loses many types of trees due to a fire
|
|
|
a desert that has low biodiversity and loses all of the saguaro cacti that are growing there
|
|
|
a tropical rainforest with high biodiversity that loses a species of fig tree due to a type of fungus
|
|
|
a coral reef with low genetic diversity in corals that loses many coral species due to an increase in water temperature

Explanation:
Detailed explanation-1: -The main direct cause of biodiversity loss is land use change (primarily for large-scale food production) which drives an estimated 30% of biodiversity decline globally. Second is overexploitation (overfishing, overhunting and overharvesting) for things like food, medicines and timber which drives around 20%.
Detailed explanation-2: -Natural disturbances include severe weather damage, fire, flooding, treefalls and even volcanic eruptions. Anthropogenic (human-caused) disturbances can alter or destroy natural habitat (like clearing land for agriculture) and/or ecological functions (like damming rivers for flood control).
